Radiology, 1991
The authors describe the magnetic resonance (MR) findings in seven patients who developed severe cerebellar symptoms and atrophy of the contralateral red nucleus following removal of unilateral neoplasms in the deep nuclei of the cerebellum. For most patients, pre- and postoperative spin-echo MR images were obtained with long repetition times (TRs) at ...

Cortical cerebellar degeneration with testicular neoplasm
Acta Neuropathologica, 1985Cortical cerebellar degeneration was found in a 28-year-old man with testicular neoplasm. The patient, who had undergone a left orchidectomy for the testicular tumor, developed progressive cerebellar symptoms with mental changes 7 months later. The autopsy revealed the spread of a malignant germ cell tumor of the testis, and cortical cerebellar ...

Cerebellar neoplasm of mixed mesenchymal and neuroepithelial origin
Journal of Neurosurgery, 1983✓ A 3½-year-old boy had a neoplasm of mixed mesenchymal and neuroepithelial origin in the cerebellar vermis. The tumor was composed of rhabdomyosarcoma and medulloblastoma. There was additional differentiation within the neuroepithelium, including neoplastic neurons, neuroblasts, astroglia, oligodendroglia, ependymal cells as well as foci of ...

BACKGROUND Deep-seated, subcortical tumors represent a surgical challenge. The traditional approach to these lesions involve large craniotomies, fixed retractor systems, and extensive white matter dissection, each with their own associated morbidity.

Cerebellar T-cell lymphoma: an unusual primary intracranial neoplasm
Neuroradiology, 1992Primary T-cell lymphoma within the central nervous system is extremely rare. Imaging characteristics appear indistinguishable from the more common B-cell lymphoma. A case of such a primary tumor is discussed and the MRI and CT findings presented.

Cerebellar glioblastoma in an NF1 patient. Is it surgical debulking really necessary?
British Journal of Neurosurgery, 2019Introduction: Neurofibromatosis type 1 is an autosomal dominant tumour syndrome with an increased risk of developing central nervous system neoplasms, mostly benign low-grade gliomas involving the optic pathway and the brainstem.

Dysplastic gangliocytoma (Lhermitte-Duclos disease) is a rare disorder, characterized by a slowly progressive unilateral tumour mass of the cerebellar cortex. The fundamental nature of this apparently benign entity and in particular its pathogenesis remain unknown. The debate, whether it represents a neoplastic, malformative or hamartomatous lesion, is

BACKGROUND Hemangioblastomas (HBMs) are benign vascular neoplasms that most commonly arise within the cerebellum. Although other vascular lesions should be considered in the differential diagnosis, HBMs rarely resemble aneurysms on neuroimaging and only ...
