Background: Crohn’s disease and ulcerative hemorrhagic colitis are forms of granulomatous inflammatory intestinal disease, which usually affects the gastrointestinal tract. There are also reported rare localizations at the skin, kidney, joints, liver and eye level. Pulmonary involvement is relatively rare, and it is most commonly reported in suppuration with bronchiectasis. On the other hand, sarcoidosis is, in principle, a thoracic localization of a granulomatosis disease, although bowel, skin and intestinal disorders are described. There is not a clear line to separate Crohn’s disease from sarcoidosis with, possibly because they are, in fact, considered to have the same inflammatory granulomatosis disease pathology. The diagnoses of the two entities, sarcoidosis and Crohn’s disease, are based on non-pathognomonic, inclusive clinical and paraclinical criteria, without elements of the mutual exclusion of typical locations. Case Report: We present a very rare case of a young male, already diagnosed with small-bowel Crohn’s disease. Granulomatous lung disease with major hemoptysis requires emergency surgery. An intraoperative assessment revealed a necrotic hemorrhagic lesion located in the left lower lobe and a lobectomy was performed. The final pathological report showed the presence of non-caseous granulomatous inflammation, with the identification of specific multinucleated giant cells. Conclusions: The identical diagnostic principles of Crohn’s disease and sarcoidosis, Crohn’s disease as a predecessor to pulmonary lesions, the clinical picture and the necrotico-hemorrhagic appearance of the unilateral pulmonary lesion, which are similar to aggressive necrotico-hemorrhagic or perforating intestinal forms, are arguments in favor of the diagnosis of pulmonary Crohn’s disease and not pulmonary sarcoidosis. At the same time, in general, the two diseases have overlapping elements, suggesting they are, in fact, not the same disease with different facets.

Background: Hydatid disease, caused primarily by Echinococcus granulosus, remains a significant public health challenge in endemic regions. While hepatic (80–85%) and pulmonary (15–20%) involvements are common, multi-organ dissemination involving rare sites such as the pericardium, diaphragm, and mediastinum occurs in less than 0.1–2% of cases. Case presentation: We present a rare case of a 26-year-old male, a farmer for 10 years, with occupational exposure to dogs and horses, with a personal history of multiple surgically treated abdominal cysts in 2016, admitted after abdominal computed tomography revealed liver cysts greater than 5 cm, as well as mediastinal and diaphragmatic cysts. Histopathological examination of the surgically resected hepatic cyst material confirmed echinococcosis. Serology was also positive for echinococcosis. Echocardiography revealed a pericardial cyst, posterior to the left atrium. Under these circumstances, antiparasitic treatment was initiated by an infectious disease specialist, followed by surgical treatment of the abdominal cysts, confirming the final diagnosis of hydatid disease, and subsequently, surgical treatment of the thoracic hydatid cysts was performed. The postoperative course was complicated by bronchial superinfection with Stenotrophomonas maltophilia, identified from bronchial aspirate culture after extended incubation and managed with trimethoprim–sulfamethoxazole. Conclusions: This case underscores the necessity of lifelong surveillance in hydatid disease, the potential role of postoperative antiparasitic therapy in preventing long-term recurrence, and the vital role of a multidisciplinary team in managing complex, disseminated relapses.

Background: Endobronchial tumors represent a heterogeneous spectrum of benign and malignant histopathological types. Selecting the optimal surgical strategy remains a multidisciplinary challenge. This study evaluates how the integration of spirometry, DLCO, and CPET can objectively stratify cardiorespiratory risk and guide surgical decision-making regarding resection type, postoperative complications, and perioperative mortality. Methods: A single-center, retrospective study was conducted between 2020 and 2025, evaluating an initial screening cohort of 93 patients with endobronchial masses. Following multidisciplinary tumor board review based on functional and anatomical criteria, 36 patients were excluded from major resection due to extensive disease or prohibitive functional risk, while 57 underwent tailored surgical interventions, including sleeve resections, lobectomies, bilobectomies, and pneumonectomies. Preoperative evaluation included spirometry, DLCO, cardiological assessment, CT, and autofluorescence bronchoscopy (AFB). Results: Spearman correlation analysis demonstrated that advanced age and higher ASA scores significantly correlated with reduced preoperative DLCO (p < 0.0001). The overall postoperative morbidity rate was 36.84% (n = 21) and perioperative mortality was 5.26% (n = 3). Stratified analysis by surgical magnitude demonstrated a significant escalation in overall complication rates from parenchymal-sparing sleeve resections (17.6%, 95% CI: 3.8% to 43.4%) to standard lobectomies (40.7%, 95% CI: 22.4% to 61.2%), bilobectomies (50.0%, 95% CI: 15.7% to 84.3%), and radical pneumonectomies (60.0%, 95% CI: 14.7% to 94.7%; p = 0.042). Severe morbidity (Clavien–Dindo Grade III–IV) was significantly lower in the sleeve resection subgroup (5.8%) compared to pneumonectomies (40.0%, p = 0.015). Fatal outcomes occurred exclusively following major resections and were attributable to ARDS and acute cardiovascular events. Conclusions: A multi-parametric preoperative protocol provides an informative framework for risk stratification in endobronchial tumor surgery, helping to describe baseline reserves and explore post-resection trends. However, the anatomical and hemodynamic magnitude of radical pneumonectomy constitutes an independent risk modifier that cannot be fully captured by preoperative functional testing alone, highlighting the exploratory nature of these single-center retrospective observations rather than a definitive algorithmic validation.

Introduction: Mediastinal lymphangiomas are rare, benign vascular malformations of the lymphatic system that are seldom diagnosed in adults. Due to their varied clinical presentation and heterogeneous imaging characteristics, they pose a significant preoperative diagnostic challenge, frequently mimicking other mediastinal masses. Materials and Methods: We conducted a thorough search of the PubMed/MEDLINE, PubMed Central, and Google Scholar databases. We included articles from 2000 to 2026. Our search yielded 150 articles, out of which we selected 45 articles. Inclusion criteria were strictly limited to adult patients with a solitary mediastinal lymphangioma. Cases involving diffuse systemic lymphangiomatosis, mixed histological features such as lymphangiomyomas or hemangiolymphangioma or studies on pediatric populations were explicitly excluded from the analysis. We also reported a case of mediastinal lymphangioma in a 42-year-old patient, which was surgically resected at the “Marius Nasta” National Institute of Pneumology in Bucharest, Romania. Case Description: An asymptomatic 42-year-old male presenting with exertional chest discomfort following minor trauma demonstrated a lower left hemithorax opacity on chest X-ray. Imagistic studies revealed a 13 × 9 × 6 cm cystic mass in the left supradiaphragmatic costophrenic recess. The patient underwent a complete radical excision. The postoperative recovery was uneventful. Histopathology confirmed a benign cystic mediastinal lymphangioma. Conclusions: Adult mediastinal lymphangiomas are rare entities that require a high index of clinical suspicion. While advanced cross-sectional imaging is invaluable for delineating their characteristics, definitive diagnosis relies on histopathological confirmation. Complete surgical resection, increasingly performed via minimally invasive approaches or standard thoracotomy, remains the therapeutic gold standard, offering an excellent long-term prognosis with virtually no risk of recurrence. For inoperable cases, several non-surgical approaches are available.
