Computed Tomography in Orbital Pathology with Clinicopathological Correlation

Abstract

Introduction: Computed Tomography (CT) is the first-line modality for radiologic evaluation of the orbit in the acute setting. Aim of our study was to determine the role of multi detector CT in orbital pathologies, to find the characteristics of CT in orbital pathologies and to correlate the CT findings with histopathological findings wherever possible Material and methods: The study was conducted in Department of Radiology and Imaging Sciences, Chettinad Hospital and Research Institute, Chennai. Patients with complaints related to traumatic and various non traumatic pathologies were included in our study. All CT examinations were performed using helical CT and reconstructed in appropriate planes Results: Among 102 patients included in our study, trauma constituted the most common etiology, followed by inflammatory and neoplastic. Lesions were analyzed for calcification, bony and paranasal sinus involvement, enhancement characteristics, lacrimal gland and optic nerve involvement. Conclusion: CT gives excellent details about bony anatomy in fractures and helps assessing presence or absence of foreign bodies. CT describes the extent of lesions in inflammatory and neoplastic etiologies, accurately assess bony destruction in neoplasms helping in the management of the orbital lesions
