ABSTRACT
Two new cases of extraventricular neurocytoma are reported. The first concerns an 18-year-old female with a left frontal lobe lesion and the second occurred in a 54-year-old female in the thoracic spinal cord. The first patient is free of disease after 18 months of follow up. The second patient is stable after 16 months of follow up. Both were operated - total excision in Case 1 and partial resection in Case 2. The latter underwent adjuvant radiotherapy due to atypical histological features. Cases of extraventricular neurocytoma are reviewed. Differences and similarities between extraventricular and central neurocytoma are outlined.

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.

An intra-conical histologically malignant solitary fibrous tumor of the orbit presented in a 28 year-old female with intact vision and exophthalmos. Total resection was achieved by means of a frontal craniotomy and orbital roof osteotomy. Evidence of a beneficial role for adjuvant treatments in this particular tumor is controversial and vision impairment is a possible side effect. Therefore they were not employed. The patient is well after two years of follow-up.

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

Seventy-two patients submitted to meningioma surgery at Pedro Hispano Hospital from 1997 to 2001 were reviewed to analyze the association between size (largest diameter of the lesion obtained from imaging examinations) and other variables regarding the biological behavior and clinical outcome of these patients. Statistically significant associations were found between tumor size and location, type of first symptom, type of physical examination, histological grade, surgical complications, postoperative CSF bursae and the need for blood transfusion. Patient's age, gender, duration of first symptom, clinical status at discharge and persistent complaints were not associated to tumor size. There was a trend towards a statistically significant association between tumor size and both grade of resection and persistent deficits. The causes and implications of the findings are discussed. Tumor size is a parameter that may interfere with the neurosurgeon's capacity to treat these patients as well as with their recovery.

Se han revisado setenta y dos enfermos sometidos a cirugía de meningioma en el Hospital Pedro Hispano entre 1997 y 2001, para evaluar la asociación entre el tamaño (mayor diámetro de la lesión obtenido a partir de los exámenes de imagen) y otras variables concernientes a la caracterización y comportamiento de la lesión. Se han encontrado asociaciones, con significación estadística, con la localización, tipo de primer síntoma, tipo de examen físico, grado histológico, aparición de complicaciones, bolsas de LCR y transfusiones de sangre. La edad, el sexo, la duración de primer síntoma, el estado al alta hospitalaria y los síntomas persistentes no se relacionan con el tamaño. Se encontró alguna relación con el tipo de exéresis y señales persistentes. Se discuten las causas e implicaciones de los hallazgos. El tamaño es un parámetro que puede interferir en la capacidad del neurocirujano para tratar estos pacientes y en la capacidad de recuperación de los mismos

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.
