Objectives: Spinal glioblastomas represent a rare entity accounting for ca 1-3% of all intramedullary tumors; data about survival, prognostic factors and therapeutic protocols are quite poor. Even with an aggressive multimodal management the spinal glioblastoma patients' survival remains poor, with rapid progression of the disease. This study reports our experience with the management of the primary intramedullary glioblastomas, also in regard to the current literature data. Patients and Methods: We retrospectively analyzed the medical records of 5 patients treated at the Department for Neuro-oncology and Spine Surgery of the Clinical Center of Belgrade, Serbia, between January 2007 and December 2016 for a primary intramedullary glioblastoma. Demographic characteristics, pre-operative data and post-operative results were then compared with previous literature regarding spinal GBMs and attempt to identify potential prognostic factors. Results: Gross total resection was achieved in two patients, while a subtotal resection was performed in the latter 3 cases; as per protocol, all patients underwent to surgery, followed by radio and chemotherapy. There were no intraoperative complications and no patients developed a new postoperative neurological defect; the median overall survival was 6 months. Progression or recurrence of disease was noted in all patients at the 3-months follow-up, despite the adjuvant treatments. Conclusions: To the date, there is a lack of consensus on specific management of spinal glioblastomas: the extent of resection can play an important role, but it appears to be not preeminent. A shorter interval between symptoms onset and treatment and a smaller extension of the tumor seem to be correlated with better outcomes and a longer overall survival. However, there is not an adjunctive viable standardized postoperative therapy yet, which results in concrete and persistent improvement of overall survival and progression free survival.

Hematological neoplastic mass lesions of the sellar region are rare. We identified five cases of hematological malignancy with first presentation in the sellar region from our departmental database of 1,405 patients (0.36%) with sellar lesions diagnosed over the 17-year period (2005–2021). All patients were females (mean age 55.2 ± 3.4 years). One patient had multiple myeloma (MM), one patient had acute myeloid leukemia (AML), while three other patients had lymphoma (intravascular lymphoma (IVL, n = 1) or non-Hodgkin’s lymphoma (NHL, n = 2). Most patients presented with ophthalmoplegia, and one patient with diabetes insipidus (DI), with short duration of symptoms (median 30 days). All patients had an elevated erythrocyte sedimentation rate and altered blood count, while patients with lymphoma had elevated lactate dehydrogenase (LDH). Sellar mass was demonstrated in three patients while the patient with IVL had an empty sella and in the AML patient posterior lobe T1W hyperintensity was lost. Two patients (IVL and NHL) presented with multiple anterior pituitary deficiencies and one patient (AML) had DI. All patients were treated with chemotherapy. Two patients responded well to treatment (one had reversed hypopituitarism), while three patients died. Differential diagnosis of sellar-parasellar pathology should include suspicion of hematological malignancy, particularly in patients with short duration of nonspecific symptoms, neurological signs (ophthalmoplegia), blood count alterations and LDH elevation, pituitary dysfunction and imaging features atypical for pituitary adenoma. Early diagnosis is crucial for timely initiation of hematological treatment aimed at inducing disease remission and partial or full recovery of pituitary function.

Background and Objectives: Before the introduction of griseofluvin, the use of X-ray radiation was the treatment of choice for tinea capitis. More than half a century later various types of tumors have been found to be associated with childhood irradiation due to tinea capitis, most commonly cancers of the head and neck, as well as brain tumors. The often unusually aggressive and recurrent nature of these tumors necessitates the need for repeated surgeries, while the atrophic skin with an impaired vascular supply due to radiation often poses an additional challenge for defect reconstruction. We present our experience in the surgical treatment of such patients. Materials and Methods: This is a retrospective cohort study. In this study, 37 patients treated for acquired defects of the scalp with a history of irradiation therapy due to tinea capitis in childhood were included in this study, 24 male and 13 female patients. The mean age at the first appointment was 60.6 ± 7.8, with the youngest included patient being 46 and the oldest being 75 years old. Patients’ characteristics, surgical treatment, and complications were analyzed and a reconstructive algorithm was developed. Results: Local flaps were used for reconstruction in 34 patients, direct sutures were used in 10 patients and 20 patients received split-thickness skin grafts for coverage of both primary and secondary defects for reconstruction of flap donor sites. One regional flap and one dermal substitute covered by an autologous skin graft were also used for reconstruction. Complications occurred in 43.2% of patients and were significantly associated with the presence of comorbidities (p = 0.001), aseptic bone necrosis (p = 0.001), as well as skin atrophy in frontal, occipital, and parietal region (p = 0.001, p = 0.042 and p = 0.001, respectively). A significant correlation between major complications and moderate skin atrophy was found only in the parietal region (p = 0.026). Conclusions: Unfortunately, many protocols developed for scalp reconstruction are not applicable in the setting of severe or diffuse scalp skin atrophy associated with high tumor recurrence rate and radiation-induced vascular impairment, such as in tinea capitis patients in Serbia. An algorithm has been developed based on the authors’ experience in managing these patients.

Background/Objectives: Endovascular embolization is an effective treatment option for cerebral arteriovenous malformation (AVM) and dural arteriovenous fistulas (DAVFs). The objective of this study was to assess the safety and efficacy of Menox^TM in patients with cranial dural arteriovenous fistulas. Methods: From January 2021 to January 2023, 19 patients with intracranial DAVFs underwent embolization procedures. All patients were treated by embolization with Menox^TM or/and in combination with other embolization products such as Onyx (Covidien, Irvine, California), PHIL (MicroVention, Tustin, California), and Squid (Balt Extrusion, Montmorency, France). Treatment approaches were selected depending on the anatomical location of the fistula. Patients were monitored and followed-up for 12 months. Results: The patients’ mean age was 56.26 ± 16.49 years. Of these 19 patients, 58% (n = 11) were treated with the Menox^TM liquid embolizing agent (LEA) alone or in combination with different LEAs, while n = 7 were treated with other LEAs and 1 patient was treated solely with coils. Complete occlusion of DAVFs with Menox^TM and other agents was evident in 68.4% (n = 13/19) of patients. Complete occlusion (100%) was observed in the sinus rectus, transverse sinus, and diploic veins of the orbital roof, while complete occlusion was observed in 50% of falcotentorial patients and 60% of superior sagittal sinus patients. The lowest rate of complete fistula obliteration was observed in the dural carotid cavernous fistula (CCF) group (25%). An intra-procedural adverse event occurred in one patient. No other post-procedural adverse events were noted. Furthermore, in patients treated with Menox^TM, total occlusion was achieved in 72.7% (n = 8) of patients, whereas the non-Menox^TM group had 62.5% (n = 5) of patients with 100% occlusion and 37.5% (n = 3) of patients with subtotal occlusion. Conclusions: Outcomes using Menox^TM alone and in combination with other agents were effective, and it is safe for the treatment of dural arteriovenous fistulas.

Background/Objectives: Spinal dural arteriovenous fistulas (sDAVFs) are the most common spinal vascular malformation and a treatable cause of progressive myelopathy, yet diagnosis and optimal management remain challenging. This study presents a nine-year institutional experience using a multidisciplinary treatment algorithm that prioritizes endovascular embolization, with surgery reserved for unsuccessful or contraindicated cases. Methods: We retrospectively analyzed 15 patients treated between 2015 and 2023, all diagnosed by MRI and confirmed by digital subtraction angiography. Endovascular embolization was attempted as the initial treatment modality in all patients using contemporary liquid embolic agents. Results: Three patients (20%) subsequently required surgical disconnection following unsuccessful or incomplete embolization. Lesions ranged from Th5 to L5, and most patients presented with varying degrees of motor deficits, gait disturbance, paresthesias, or sphincter dysfunction. Neurological improvement occurred in all but one patient, and no treatment-related complications were observed. Prior embolization attempts aided intraoperative localization in surgically treated cases, facilitating precise fistula identification. Conclusions: These findings demonstrate the feasibility and favorable outcomes of a multidisciplinary, stepwise treatment strategy in this single-center experience. Endovascular embolization served as the initial treatment modality, while surgical disconnection provided an effective complementary option in selected cases where embolization was unsuccessful or incomplete.
