We present the case of a 17-month-old male patient with a bilateral Duane syndrome type 1 associated to unilateral cochleovestibular dysplasia, perilymphatic fistula and recurrent meningitis. Diagnosis was carried out by MRI and CT scan. His management and treatment are described, as well as the postoperative evolution. We believe this is an exceptional case due to the low frequency of this syndrome, as well as to the otoneurological complications.

Primary cutaneous B-cell lymphoma (PCBCL) has three subtypes, among those, the leg type variant is the rarest with the highest rates of relapse and recurrence making it an intriguing focus for researchers. Nevertheless, prior to framing a diagnosis solely based on the lesion's location, it is prudent to reconsider whether it is genuinely a primary cutaneous B-cell lymphoma (PCBCL) or if it aligns more closely with the more prevalent lymphoma variants such as diffuse large B-cell lymphoma (DLBCL) with cutaneous involvement. We are reporting a case of an 85-year-old African American lady, who presented with unilateral left leg DLBCL with cutaneous involvement.

Introduction: Dural arteriovenous fistulas (dAVF) are abnormal anastomoses between meningeal arteries and dural venous sinuses. Typically, dAVF treatment involves an endovascular or microsurgical approach. Anterior ethmoidal artery (AEA) dAVFs pose unique challenges due to their anatomy and location.

Rationale: Ependymomas are commonly prevalent intramedullary neoplasms in adults, with hardly any cases of exophytic extramedullary ependymoma being reported. Meningiomas, on the contrary, are one of the most common intradural extramedullary (IDEM) tumors. However, the occurrence of both IDEM tumors simultaneously is extremely rare.

To investigate the value of preoperative MRI features and ADC histogram analysis for evaluating tumor-infiltrating CD8+ T cells in meningiomas. In this single-center cross-sectional study, we conducted a retrospective analysis of clinical, imaging, and pathological data from 84 patients with meningioma and performed immunohistochemical staining to quantitatively evaluate CD8+ T cells. Using X-Tile software, we divided the patients into high-and low-CD8+ T cells groups based on cut-off values.

Purpose: We used knowledge discovery from radiomics of T2-weighted imaging (T2WI) and contrast-enhanced T1-weighted imaging (T1C) for assessing relapse risk in patients with high-grade meningiomas (HGMs).
Methods: 279 features were extracted from each ROI including 9 histogram features, 220 Gy-level co-occurrence matrix features, 20 Gy-level run-length matrix features, 5 auto-regressive model features, 20 wavelets transform features and 5 absolute gradient statistics features. The datasets were randomly divided into two groups, the training set (~ 70%) and the test set (~ 30%).
