OBJECT Medial acoustic neuroma is a rare entity that confers a distinct clinical syndrome. It is scarcely discussed in the literature and is associated with adverse features. This study evaluates the clinical and imaging features, pertinent surgical challenges, and treatment outcome in a large series of this variant. The authors postulate that the particular pathological anatomy with its arachn...

Surgical Approaches for Resection of Acoustic Neuromas A neuromas are the most common tumors of the cerebellopontine angle. Most are benign lesions that grow from the transition point between the central and peripheral myelin. They cause a wide variety of symptoms such as hearing loss, tinnitus, and balance abnormalities. Large lesions compress the contents of the posterior fossa and may cause ...

It is widely accepted that giant acoustic tumors (4 cm or more in diameter) require surgical treatment. However, this is a demanding technical procedure, with possible postoperative neurological dysfunction and complications. Giant tumors are frequent in specialized centers, representing about 15% of the total number of acoustic neuromas. The size of the tumor is an important factor concerning ...

A detailed analysis of the CT findings in 75 cases of acoustic neuroma is presented. The method of examination included plain and enhanced CT, metrizamide CT cisternography (M-CTC), and gas CT cisternography (gas-CTC). The common CT appearances of acoustic neuromas were as follows: 93.6% appeared as isodense or hypodense on precontrast scan; homogeneous enhancement was observed in 53.8% on post...

BACKGROUND Facial nerve neuromas are extremely rare and are often mistaken for acoustic neuromas when located near the vestibular nerve. Usually presenting with facial weakness and hearing loss, facial nerve neuromas of the cerebellopontine angle have commonly been managed by surgery. We present the first reported case of a facial nerve neuroma treated with fractionated stereotactic radiotherap...
