ABSTRACT
ABSTRACT To our knowledge, we report the first case of an extraconal orbital cystic schwannoma in Brazilian literature. The tumor grew slowly and progressively and was associated with minimal eccentric proptosis and diplopia. The radiologic study (orbital computed tomography) revealed a rounded, encapsulated, and extraconal cystic mass in the superior medial region of the right orbit in the supraorbital and supratrochlear nerve topography. An anterior orbitotomy with full excision of the tumor was performed, and the histopathology examination revealed that the tumor was a schwannoma. After the surgery, the patient experienced total remission of his symptoms.
RESUMO
RESUMO Os autores relatam o primeiro caso de schwannoma orbitário extraconal cístico relatado na literatura brasileira. O tumor apresentou aparecimento lento e progressivo, associado a proptose excêntrica e diplopia leves. O exame de imagem (tomografia computadorizada de órbita) revelou uma lesão nodular, arredondada, capsulada, extracônica, cística, na região súpero-medial de órbita direita, na topografia do nervo supraorbitário e supra-troclear. O paciente foi submetido à orbitotomia por via anterior, com exérese integral da tumoração. O exame histopatológico revelou o diagnóstico de schwannoma. Após a cirurgia, o paciente teve regressão total dos sintomas.
