RESUMO
INTRODUCTION: Vascular malformations are uncommon causes of aqueductal obstruction. To our concern, only one case of hydrocephalus caused by a venous varix draining an unruptured arteriovenous malformation has been described in the literature. CASE REPORT: We report the case of a 70-year-old woman presenting with progressive cognitive impairment, gait disturbance and urinary incontinence. Magnetic resonance imaging and magnetic resonance angiography revealed a large venous varix draining an unruptured arteriovenous malformation causing hydrocephalus. CONCLUSION: Although uncommon, it is necessary to consider the presence of a vascular malformation in adults who presented with signs of aqueductal obstruction.

A cavernous malformation involving the Gasserian ganglion, 2nd and 3rd divisions of the trigeminal nerve on the left side was resected via an extradural route in a 54 year old male. Cavernous malformations of the cranial nerves are rare. Specific origin from the trigeminal nerve has not been previously reported.

Una malformación cavernosa afectando el ganglio de Gasser, la segunda y tercera divisiones del nervio trigémino fue resecada por vía extradural en un varón de 54 años. Las malformaciones de los nervios craneales son raras. Su origen específico en el nervio trigémino no ha sido descrito previamente

A case of conventional intramedullary osteosarcoma (epithelioid subtype) with 10 years of evolution and another of high grade surface osteosarcoma of the chondroblastic type, both in the skull, gave rise to several diagnostic and therapeutic difficulties. Key points concerning the definition, classification, imaging, clinical series data and treatment options available for skull osteosarcoma are highlighted.

Six cases of cavernous abducens nerve schwannoma have been reported. A new case of a 39 year old female with abducens nerve paresis, exophtalmos, chemosis and headache due to a 1,36 x 2,58 cm cystic right cavernous abducens nerve schwannoma is presented and discussed. The cavernous sinus was opened between the trochlear and ophthalmic nerves. A portion of the tumor capsule adherent to the internal carotid artery was not resected. No deficits were added by surgery. After 30 months of follow up there is no evidence of relapse and only abducens nerve paresis persists.
