To our knowledge, less than 20 cases have been related up to now under different names like as "lipomatous medulloblastoma, lipidized medulloblastoma,(More)
Cerebellar liponeurocytoma, a rare, newly identified CNS neoplasm of adults, is characterized by advanced neuronal/neurocytic and focal lipomatous differentiation, low proliferative potential and a favorable clinical prognosis. Despite the different age distribution and benign biological behavior, the cerebellar liponeurocytoma shares several features with(More)
The authors report two cases of amyotrophic lateral sclerosis (ALS) misdiagnosis (a craniocervical junction disorder, and a cervical spinal cord ependymoma). They review some causes of ALS-like syndrome and propose a protocol to be adopted for the study of all patients who present clinical abnormalities suggesting ALS.

The existence of an interaction between mast cells and different fibrotic conditions has long been observed. Tryptase, the most abundant protein product of human(More)
Subependymomas are benign tumors that occur predominantly in the ventricular system. We describe a case of a 57-year-old man with a large cerebellopontine angle (CPA) tumor which expanded into the jugular foramen. Complete surgical excision of the tumor was achieved through a retrosigmoid approach and the histopathological diagnosis was subependymoma.(More)
The authors report a case of paraplegia caused by a lumbar intraspinal paracoccidioidomycosis (PCM) granuloma. Clinical neurological diagnosis of a compressive spinal cord lesion was confirmed by spinal magnetic resonance imaging (MRI). Patient was submitted to surgery with total excision of the lesion. Histopathological analysis confirmed the diagnosis of(More)
