Abstarct: Remote cerebellar hemorrhage as a rare complication of supratentorial surgery was already first described in the 1970s by Yasargil. Its incidence ranges from 0.2% to 0.4% after supratentorial craniotomies. Although its incidence is low, the volume of reports with remote cerebellar hemorrhage in the literature has been growing in recent times. The authors report here a new case of a controlateral remote cerebellar hemorrhage after 24 hours of supratentorial craniotomy for a solitary brain metastasis of a pulmonary adenocarcinoma in a 59 year-old male patient with unbalanced high blood pressure.Supratentorial craniotomy, Remote cerebellar hemorrhage, CT scan

Thalamic astrocytomas are rare central nervous system tumors that account for 1%-1.5% of all brain tumors. Their Clinical features depend on anatomical involvement. For these tumors, gross total resection is so difficult due to their deep location and also the infiltration of the optic pathway or brain stem. Unilateral adult thalamic locations are rarely described in the literature. Their radiological features often suggest lymphoma. The authors report here a new case of a primary unilateral thalamic pilocytic astrocytoma mimicking lymphoma diagnosed after a stereotactic core biopsy in a 62-year-old male patient with von Recklinghausen's disease and which is responsible for Dejerine–Roussy syndrome. The authors will proceed with a comprehensive review of literature regarding this rare entity.

Cerebellar liponeurocytoma or lipomatous medulloblastoma is a rare oncological entity. Knowledge regarding the management and outcomes of these rare tumors are still evolving. Very few cases have been described previously in the literature. The authors report a case of a middle-aged woman operated on twice, 8 years apart, with uneventful postoperative follow-ups. Radiological characteristics were revealed atypically on the computed tomography scan and magnetic resonance imaging. Histopathological study supported a cerebellar liponeurocytoma with classic immunohistochemical features. Through this report, the authors aim to describe atypical radiological and histopathological features of this rare entity with good outcome by going through a comprehensive review of the existing literature.
