Review Case Reports
Intra-neural Ewing's sarcoma of the fibular nerve - Case report, radiological findings and review of literature.
Intraneural Ewing sarcoma (ES) was first described in 1918 by Stout in a tumor of the ulnar nerve. These tumors are in the category of ES family of tumors, together with ES of bone, extraosseous ES, and primitive neuroectodermal tumor. ES typically occurs in the second decade of life; only 20% of cases affect elder people. The most frequently involved sites are the craniospinal vault and cauda equina, while the peripheral nerve location is extremely rare (only 11 cases mentioned in the literature to date). ⋯ The challenge of intraneural extraosseous ES consists of the right balance between the necessity to consider a potential malignant nature of the lesion and perform adequate surgical excision in a relatively brief time from the first clinical examination and the fact that these are extremely rare pathologic entities among most frequent cases of completely benign tumors, which could even have the same clinical and radiologic presentation. For this reason, a multidisciplinary setting with a team of neurosurgeons, orthopedic specialists, radiologists, pathologists, and oncologists should manage these cases as soon as a pathologic diagnosis is available. More attention should be focused on other therapies that effectively manage microscopic pathologic involvement, without increasing the risk of postoperative morbidity.

Case Reports
Sellar Atypical Teratoid/Rhabdoid Tumor Presenting with Subarachnoid and Intraventricular Hemorrhage.
Atypical teratoid/rhabdoid tumors (ATRT) are uncommon malignancies of the central nervous system and are often difficult to distinguish radiographically and pathologically from other common tumors. We present the first case of sellar ATRT presenting with subarachnoid hemorrhage (SAH) and intraventricular hemorrhage (IVH). ⋯ To the best of our knowledge, although known to present with intratumoral hemorrhage, to date, no cases of sellar ATRT have presented with SAH or IVH have been reported. Considering our finding that ATRT can present with SAH and IVH, establishing the correct diagnosis using radiographic imaging, gender, pathological findings, and molecular markers is paramount for speedy treatment and management.

Primary lymphoma of the skull base (PLSB) is an extremely rare neoplasm and not much is known regarding the clinical features of, treatment strategies for, and prognoses of these lesions. We investigated the manifestations and clinical outcomes of Chinese patients with PLSB. ⋯ PLSB is a rare disease and a diagnostic challenge, with most cases in the Chinese due to diffuse large B-cell lymphoma. We found that the incidence peaked in middle and old age, and the cavernous sinus was usually affected. Multidisciplinary treatment involving surgical biopsy, chemotherapy, and radiotherapy was an effective therapeutic strategy.
