“…This is in accordance to literature stating majority of the acoustic neuromas appear after 50 years of lif. 27 In this study, out of 55 patients 35 (63.6.0%) were females and 20 (36.4%) were males. This is also in accordance with the literature, which states that the acoustic neuroma is commoner in females with female to male ratio 3:2.…”

“…This is also in accordance with the literature, which states that the acoustic neuroma is commoner in females with female to male ratio 3:2. 27 Most of the acoustic neuromas in this study were better visualized after contrast enhancement. This fact is supported by a studywhich states that contrast enhanced T1-W MR image enhances the capacity to visualize the tumour margins and its intrameatal component.…”

ABSTRACT… Objectives: To determine the diagnostic accuracy of magnetic resonance imaging in the detection of acoustic neuroma taking histopathology as gold standard. Study Design: Cross-sectional survey. Setting: The Department of Diagnostic Radiology, Lahore General Hospital, Lahore. Duration of Study with Dates: Study was completed in six months after approval of synopsis from 14-07-2009 to 14-01-2010. Subjects & Methods: This study comprised of 55 patients with clinical suspicion acoustic neuroma. Magnetic resonance imaging on a 1.5-T Philips whole body magnetic resonance system was performed. The cases were operated and histopathological results were recorded. The results of magnetic resonance imaging and histopathology were compared taking histopathology as gold standard. Results: Out of 55 patients, 43 patients (78.2%) had acoustic neuroma on magnetic resonance imaging. After comparison of results of magnetic resonance imaging with histopathology, the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of magnetic resonance imaging were 97.7%, 91.7%, 97.7%, 91.7% and 96.4% respectively. Conclusion: Magnetic resonance imaging is a highly accurate, non-invasive, safe and convenient imaging modality for the evaluation of acoustic neuromas and is valuable for guiding surgical biopsies thereby decreasing unnecessary intervention. It allows detection of small tumours which is very useful in tumour characterization and plays an integral role in early detection, planning management and estimating patient's prognosis.

Introduction Vestibular schwannoma (also known as acoustic neuroma) is a benign tumor whose cells are derived from Schwann sheaths, which commonly occurs from the vestibular portion of the eighth cranial nerve. Furthermore, vestibular schwannomas account for ∼8% of intracranial tumors in adults and 80 to 90% of tumors of the cerebellopontine angle. Its symptoms are varied, but what stands out most is a unilateral sensorineural hearing loss, with a low index of speech recognition. Objective Describe an atypical manifestation of vestibular schwannoma. Case Report The 46-year-old woman had vertigo and binaural hearing loss and fullness, with ear, nose, and throat examination suggestive of cochlear injury. After 6 months, the patient developed worsening of symptoms and onset of right unilateral tinnitus. In further exams the signs of cochlear damage remained, except for the vestibular test (hyporeflexia). Magnetic resonance imaging showed an expansive lesion in the right cerebellopontine angle. Discussion This report warns about the atypical manifestations of vestibular schwannoma, which must always be remembered in investigating and diagnosing hearing loss.

We present a case of a fifty-year-old male patient who was referred to the Oral Medicine Department with a complaint of a salty taste. History taking subsequently revealed that the patient was also experiencing intermittent numbness of his left lower lip, tinnitus, and a feeling of fullness in the left ear. Magnetic resonance imaging was performed which revealed a large vestibular schwannoma affecting the left vestibulocochlear nerve, which was treated surgically. This case shows the importance of taking a detailed history in a patient presenting with an initial complaint of oral dysgeusia. It also highlights the possibility of significant underlying pathology, presenting with initial low level, nonspecific complaints such as an altered taste, and the rationale for imaging patients who report unilateral facial hypoesthesia.
