A cystic haemorrhagic lesion located in the cerebellopontine angle cistern

Abstract

A 74-year-old female presented with progressive left-sided hearing loss, tinnitus, and vertigo. Her audiometric tests indicated severe left-sided sensorineural hearing loss and the neurological examination revealed left-sided horizontal nystagmus and cerebellar disturbance. A CT scan was performed on admission (Fig. 1A, B). An MRI was also performed, which included T1-weighted (Fig. 1C), T2-weighted (Fig. 1D), and constructive interference in steady state (CISS) images (Fig. 1E).

A cystic haemorrhagic lesion located in the cerebellopontine angle cisternJournal of Clinical NeuroscienceVol. 19Issue 11PreviewA cavernous angioma (CA) in the cerebellopontine angle (CPA) represents a neurosurgical challenge because of the surrounding structures, present in a restricted surgical field. Most of the reported CA in the CPA extend from the internal acoustic meatus (IAM).1,2 CA arising in the CPA without involving the IAM and the dura around the skull base are extremely rare. The few reports available on these lesions3–11 are summarized in Supplementary Table 1. Adachi et al.3 classified CA of the CPA into two categories: the IAM and the cisternal types. Full-Text PDF
