ABSTRACT

Hemorragia intracraniana de ocorrência em pós-operatório é grave complicação das cirurgias intracranianas. O aparecimento de foco hemorrágico em regiões distantes ao sítio operatório original é considerado incomum, e muitas vezes ignorado pelos médicos assistentes. A fisiopatologia envolvida no processo não é de todo compreendida, apesar das diversas teorias já propostas. São apresentados três casos de hemorragia á distancia da área cirúrgica, no pós-operatório de dois pacientes portadores de meningeoma do seio cavernoso e de um submetido à clipagem de aneurisma intracraniano.

ABSTRACT

We report a case of cellular schwannoma, a rare benign nerve-sheath tumor in a 27 year-old woman. It was presented as a voluminous lesion in the paraspinal region that caused lumbar vertebral body destruction. These features, in association to the microscopic aspects of a hypercellular, pleomorphic neoplasm may lead to a false impression of a malignant tumor. Therefore, it is important to have an accurate examination to confirm the benign nature of this tumor thus avoiding unnecessary therapy
