Sciatic Nerve Schwannoma at Sciatic Foramen: Importance of Transvaginal Sonography Guided Biopsy and Magnetic Resonance Imaging in its Diagnosis
Journal Title: Journal of Clinical and Diagnostic Research - Year 2018, Vol 12, Issue 6
Abstract
ABSTRACT Schwannomas are truly encapsulated benign tumours associated with the nerves arising from the schwann cells. Schwannomas arising from the sciatic nerve is of rare occurrence and is estimated to be less than one in hundred cases of schwannomas detected. Generally sciatic nerve schwannomas symptomatically mimic sciatica due to herniated disc or sometimes it may be asymptomatic and incidentally detected. In this case report, we are describing a case of asymptomatic middle aged female patient, who is a follow up case of hysterectomy and bilateral salpingo-oophorectomy for a gyanecological malignancy around 5 years back. During routine follow up sonography (TVS), a mass was detected deep within the pelvis, which was further investigated with MRI and found to be a possible nerve sheath tumour of sciatic nerve at the left sciatic foramen. Further TVS guided biopsy and histopathological correlation, confirmed it to be an ancient schwannoma (neurilemmoma).
