Role of MRI in non-traumatic orbital lesions

Abstract

A descriptive study of 50 patients was conducted for evaluation of non-traumatic orbital lesions. The most common presenting symptom was diminution of vision (66%) followed by proptosis (50%). Most commonly encountered lesions were infective and inflammatory lesions, contributing 42% of total lesions. MRI was 100% specific in cases of orbital cysticercosis as scolex could be identified easily. Various other non-traumatic orbital lesions included were Coloboma, retinoblastoma, lacrimal gland pathologies, vascular hemangiomas etc. MRI is the imaging modality of choice for suspected non traumatic orbital lesions except where MRI is contraindicated.
