An ectopic thyroid (ET) involves numerous scenarios of detection and outcomes, while its current management is not standardised. A mediastinal ET (MET) represents a low index of suspicion. In this paper, we introduce a 47-year-old female who was accidentally identified with an MET, and a modern surgical approach was provided. An anterior mediastinal mass of 3.2 cm was found at CT upon a prior COVID-19 infection. Previous to the infection, she experienced non-specific complaints for a few months (intermittent night sweats, facial erythema, chest pressure, and dyspnoea). Also, CT identified a thymus-like mass and a left adrenal incidentaloma of 3 cm. The endocrine panel was normal, and the subject declined further investigations. She was re-admitted 12 months later: the MET had increased +1 cm (+45% volume) and was confirmed at a 99mTc pertechnetate scintigraphy. Noting the symptoms, mediastinal anatomy, and size change, the MET was removed via a minimally invasive trans-cervical approach (eutopic gland preservation) with the help of a Cooper thymectomy retractor (which also allowed for a synchronous thymus mass resection). No post-operatory complications were registered, the thyroid function remained normal, and the mentioned symptoms were remitted. A histological exam confirmed a benign MET and thymus hyperplasia, respectively. To conclude, this case pinpoints important aspects, such as the clinical picture became clear only upon thoracic surgery due to the complete remission of the complaints that initially seemed widely non-specific. The incidental MET finding was associated with a second (adrenal) incidentaloma, a scenario that might not be so rare, following multiple imaging scans amid the COVID-19 era (no common pathogenic traits have been identified so far). The co-presence of a thymus mass represented one more argument for surgery. Minimally invasive cervicotomy associated with eutopic gland conservation and the use of a Cooper thymectomy retractor highlight modern aspects in video-assisted thoracic surgery, which provided an excellent outcome, involving one of the lowest mediastinal thyroids to be removed by this specific procedure. Awareness of such unusual entities helps inform individualised, multidisciplinary decisions for optimum prognoses.

The COVID-19 pandemic brought into prominence several emergent medical and surgical entities, but, also, it served as trigger and contributor for numerous apparently unrelated ailments such as arterial and venous thromboembolic complications. Additional risk factors for these thrombotic traits may be concurrent (known or unknown) malignancies, including at hepatic level. Among these, cholangiocarcinoma (CCA), a rare cancer of intra- and extra-hepatic biliary ducts, represents a very aggressive condition that typically associates local and distant advanced stages on first presentation requiring a prompt diagnosis and a stratified management. This neoplasia has been reported to present a large spectrum of paraneoplastic syndromes in terms of dermatologic, renal, systemic, neurologic, endocrine, and cardiovascular settings, that, overall, are exceptional in their epidemiologic impact when compared to other cancers. Our aim was to introduce a most unusual case of CCA-associated distant thrombosis in a male adult who initially was considered to experience COVID-19-related thrombotic features while having a history of obesity and bariatric surgery. This is a hybrid type of paper: this clinical vignette is accompanied by two distinct sample-focused analyses as a basis for discussion; they each had different methods depending on their current level of statistical evidence. We only included English-published articles in PubMed, as follows: Firstly, we conducted a search of reports similar to the present case, regarding distant vein thrombosis in CCA, from inception until the present time. We performed a literature search using the keywords “cholangiocarcinoma”, “thrombosis”, and “Trousseau’s syndrome” and identified 20 cases across 19 original papers; hence, the current level of evidence remains very low Secondly, we searched for the highest level of statistical evidence concerning the diagnosis of venous thrombosis/thromboembolism in patients who underwent COVID-19 infection (key search terms were “COVID-19”, alternatively, “coronavirus”, and “SARS-CoV-2”, and “thrombosis”, alternatively, “thromboembolism”) and included the most recent systematic reviews and meta-analyses that were published in 2024 (from 1 January 2024 until 8 July 2024). After excluding data on vaccination against coronavirus or long COVID-19 syndrome, we identified six such articles. To conclude, we presented a probably unique case of malignancy with an initial manifestation consisting of recurrent superficial vein thrombosis under anticoagulation therapy, with no gastrointestinal manifestations, in a patient with a notable history for multiple episodes of SARS-CoV-2 infection and a prior endocrine (gastric) surgery. To our knowledge, this is the first identification of a CCA under these specific circumstances.

Background: Maximizing tumor resection is a key prognostic factor in glioma surgery. Intraoperative cerebral ultrasonography (IOUS) offers real-time, cost-effective guidance that can enhance the extent of resection (EOR) and gross total resection (GTR) rates, but data remain heterogeneous. Methods: We conducted a retrospective analysis of a prospective observational database including patients with gliomas undergoing surgery with or without IOUS guidance in one tertiary neurosurgical center. Inclusion criteria were preoperative magnetic resonance imaging-suspected gliomas, intended GTR, and available early postoperative imaging. Outcomes were compared using propensity score matching. In addition, a systematic literature review covering 2018–2024 was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: A total of 38 patients were included after matching, with 19 patients in each group. IOUS use significantly improved the mean EOR (85.0% vs. 66.2%, P = 0.028) and GTR rate (47.4% vs. 10.5%, P = 0.029). Benefits were more pronounced in tumors larger than 10 cm ³ . A learning curve effect was observed, with increasing resection rates over time. The literature review identified nine relevant studies, with GTR rates ranging from 42% to 91%, and recent studies showing improved outcomes with advanced IOUS techniques. These findings should be interpreted cautiously given the small sample size and single-center design. Conclusion: IOUS significantly enhances resection outcomes in glioma surgery and demonstrates a progressive benefit with surgeon experience. Given its versatility, low cost, and growing integration with technologies such as contrast-enhanced ultrasound and artificial intelligence, IOUS remains a fundamental tool in modern neurooncology. Future multicenter prospective studies are needed to standardize its use and assess long-term patient outcomes.

Background/Objectives: This study explores the micro-structure of celiac ganglia using two-photon microscopy (TPM) to highlight histological features in neurodegenerative conditions. Neurodegenerative diseases like Parkinson’s disease (PD) are linked to dysautonomia, impacting autonomic regulation and leading to significant gastrointestinal and autonomic symptoms. Our research compares imaging results from TPM and SHG microscopy, visualizing neuronal integrity, collagen distribution, and the architectural organization of celiac ganglia. SHG specifically allows detailed imaging of collagen fibers and neuronal structures, revealing alterations in collagen density and organization that correlate with dysautonomia. Methods: The cross-sectional study was conducted at “Dr. Carol Davila” Central Military Emergency University Hospital, Bucharest, Romania, involving 70 participants diagnosed with PD (Hoehn and Yahr stages 2–4), including 35 with dysautonomia and 35 without. We utilized samples from PD patients with and without dysautonomia, applying immunohistochemical markers for sympathetic neurons. Results: Our findings reveal significant pathological changes in neuronal structure and collagen architecture. Immunohistochemical markers (neuropeptide Y, neurofilament heavy chain (NF-H), and tyrosine hydroxylase) were employed to characterize sympathetic neurons, while TPM and SHG provided high-resolution imaging of neuronal integrity and extracellular matrix composition. Conclusions: These imaging techniques present a promising tool for early diagnosis and assessment of neurodegeneration and dysautonomia in PD patients. Moreover, these techniques may represent a critical bridge between histopathological findings and clinical manifestations, underscoring their role in enhancing our understanding of neurodegeneration and autonomic dysfunction in Parkinson’s disease.

Background: Ectopic organ-associated conditions belong to the larger panel of developmental ailments, and among this challenging medical and surgical chapter, ectopic endocrine glands-related picture is mostly focused on the presence of the ectopic parathyroid and thyroid. Ectopic thyroid tissue within mediastinum (ETTM) stands for a less common ETT site; while, globally, less than 1% of the mediastinum masses are ETTM. Objective: We aim to introduce a rare case of ETTM in a senior lady to whom one-time synchronous thyroidectomy with ETT removal was successfully performed via a minimally invasive modern procedure upon cervicotomy and intra-operatory use of the Cooper thymectomy retractor. Results: The panel of pros and cons with respect to providing endocrine thoracic surgery for ETTM resection in a 73-year-old subject is discussed amid a PubMed search of original English-language original reports from January 2000 until 15 August 2024 in order to identify similar distinct cases (individuals of 70 years or older who underwent surgery for ETTM). Conclusions: 1. We propose the term “three-leaf-clover thyroid” to capture the imaging essence of having an enlargement of both (eutopic) thyroid lobes and ETTM. 2. The modern surgical approach under these circumstances provided a rapid patient recovery with a low rate of complications and a minimum hospital stay. Hence, the procedure may be expanded to older patients after a careful consideration of their co-morbidities and of the need to releasing connected complaints (e.g., a 7-month history of intermittent dyspneea was found in this case with post-operatory remission). 3. The management remains a matter of individualised decision, and age may not be a limiting factor. 4. At the present time, this case adds to the very limited number of similar published cases in the mentioned age group that we could identify (seven patients, aged between 72 and 84; male-to-female ratio of 5 to 2; the rate of malignant ETTM was 3/7); of these cases, not all were reported to have a trans-cervical approach, and none reported the use of the Cooper thymectomy retractor to help the overall surgical procedure. This innovative surgical procedure offers the advantage of avoiding a sternotomy incision which has clear functional and aesthetic implications, while the video-assisted approach allows optimal visualization of the mediastinal anatomy and safe vascular sealing under visual control, without the risk of a major hemorrhage.

Poorly differentiated thyroid malignancy, a rare histological type of aggressive thyroid malignancy with associated difficulties and gaps in its histological and molecular characterization, might lead to challenging clinical presentations that require a prompt multimodal approach. This case study involved a 56-year-old, non-smoking male with a rapidly developing goiter (within 2–3 months) in association with mild, non-specific neck compressive symptoms. His medical history was irrelevant. A voluminous goiter with substernal and posterior extension up to the vertebral bodies was detected using an ultrasound and computed tomography (CT) scan and required emergency thyroidectomy. He had normal thyroid function, as well as negative thyroid autoimmunity and serum calcitonin. The surgery was successful upon “Y” incision, which was used to give better access to the retrosternal component in order to avoid a sternotomy. Post-operatively, the subject developed hypoparathyroidism-related hypocalcemia and showed a very high serum thyroglobulin level (>550 ng/mL). The pathological report confirmed poorly differentiated, multifocal thyroid carcinoma (with an insular, solid, and trabecular pattern) against a background of papillary carcinoma (pT3b, pN0, and pM1; L1; V2; Pn0; R1; and stage IVB). The subject received 200 mCi of radioiodine therapy for 6 weeks following the thoracic surgery. Whole-body scintigraphy was performed before radioiodine therapy and showed increased radiotracer uptake at the thyroid remnants and pre-tracheal levels. Additionally, single-photon emission computed tomography combined with CT (SPECT/CT) was performed, and confirmed the areas of intense uptake, in addition to a moderate uptake in the right and left pulmonary parenchyma, suggesting lung metastasis. To conclude, an overall low level of statistical evidence exists regarding poorly differentiated malignancy in substernal goiters, and the data also remains scarce regarding the impact of genetic and molecular configurations, such as the BRAF-positive profile, in this specific instance. Furthermore, multimodal management includes additional diagnosis methods such as SPECT/CT, while long-term multilayered therapy includes tyrosine kinase inhibitors if the outcome shows an iodine-resistant profile with a poor prognosis. Awareness remains a key factor in cases of a poorly differentiated carcinoma presenting as a rapidly growing goiter with substernal extension in an apparently healthy adult. A surgical approach, while varying with the surgeon’s skills, represents a mandatory step to ensure a better prognosis. In addition to a meticulous histological characterization, genetic/molecular features provide valuable information regarding the outcome and can further help with the decision to use new anti-cancer drugs if tumor response upon radioiodine therapy is no longer achieved; such a development is expected in this disease stage in association with a BRAF-positive configuration.
