[Intramedullary schwannomas. Report of two cases].

Intramedullary schwannomas are benign tumors that arise from clusters of Schwann cells embedded in the medullary parenchyma. They are very rare and account for 0.3 to 1.

[Remote cerebellar hemorrhage after lumbar spinal fluid drainage. Report of two cases and literature review].

Remote cerebellar hematoma, a cerebellar hematoma occurring after performing a surgical procedure in an anatomical distant area from the cerebellum, is a rare complication. It has been reported after supratentorial surgery and, less often, after spinal surgery with dural opening with important loss of cerebrospinal fluid. We report the occurrence of remote cerebellar hemorrhage after lumbar spinal fluid drainage in two patients with suspected normal pressure hydrocephalus.

[Pseudo-emesis gravidarum caused by complicated cerebral venous angioma].

Introduction: Emesis gravidarum is a common pathology rarely requiring hospitalization to control hydroelectrolytic and metabolic alterations. Although it is typical in the first quarter of pregnancy, it can appear in any moment of the gestation. On the other hand, venous angioma (VA) is the most frequent cerebral vascular malformation.

[Cocaine abuse as precipitating factor of tumoral bleeding in an oligoastrocitoma].

Cocaine abuse has been associated with a variety of intracranial haemorrhagic disorders, such as intracerebral, subdural or subarachnoidal haemorrhage. Frequently, these patients harbour underlying vascular malformations, like cerebral aneurysms or arteriovenous malformations (AVM). To the best of our knowledge only two cases of tumoral haemorrhage induced by cocaine abuse have been previously reported.

[Anterior cervical interbody fusion with treathed cylindrical bone versus bak-cace: a comparative study].

The authors conducted a prospective and randomized study in 44 consecutive patients requiring cervical interbody fusion following anterior cervical discectomy to compare the efficacy of heterologous threaded cylindrical bone (Unilab Surgibone) versus titanium implant (Bak-C; Spine-Tech, Minneapolis ). The patients were evaluated between two and five years postoperatively and the objectives of the study were to assess the potential differences in implant shifting, interespace collapse, angulation, maintenance of cervical alignment and lordosis, and clinical and radiographic fusion success rates between the two fusion substrates. Clinical results were satisfactory with both types of implant.

[Carpal tunnel syndrome? Case report].

A patient with an initial misdiagnosis of carpal tunnel syndrome is presented. The clinical manifestations were suggestive of such diagnosis, but there were some anamnesis and exploratory aspects requiring to establish a differential diagnosis. Painful syndrome was caused by a brachial plexus compression at the costoclavicular region due to a subclavicular hematoma in a patient under anticoagulant treatment.

[Spinal extradural lipomatosis. Revision of 108 cases. Case induced by exogenous contribution of ACTH].

Authors present a male patient with Spinal Extradural Lipomatosis, previously treated of a cerebral astrocytoma with surgery and radiotherapy, after which he received ACTH for a long period of time. Clinical manifestations were rachialgia, paraparesia with pain and dysestesias in both lower extremities. Diagnosis was carried out by Magnetic Resonance imaging.
