Microsurgical resection of a cavernous angioma that involves the optic pathway using a pterional approach: a case report and literature review

British Journal of Neurosurgery
Xi-Yan Sun, Feng Yu

Abstract

Cavernous angiomas affecting the optic pathway are rare. This report describes the case of a 12-year-old girl who presented with a 10-month history of right-sided blurred vision caused by a cavernous angioma affecting the right side of the optic chiasm. The computed tomography (CT) scan demonstrated a hyperdense image with calcifications. T1-weighted magnetic resonance imaging (MRI) showed a sellar mass with uneven isointensities and hyperintensities, while T2-weighted showing a heterogeneous signal, which was initially misdiagnosed as a craniopharyngioma. The patient underwent complete resection of the mass using a pterional approach, which rapidly decompresses and protects the optic nerve function, rather than conservative treatment or cranial irradiation. Postoperative histopathology confirmed the diagnosis of a cavernous angioma.

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.
