Retinoblastoma Pseudotumour Haemangioma.

Orbital problems can be of great concern to the patient, family and the physician. For the patient there can be permanent cosmetic deficit, ophthalmological deficit with loss of vision or the eye, and even loss of life. Many a times the diagnosis of orbital tumors is not clear even after thorough clinical examination. CT is useful to characterize: the precise location of the lesion- the intraconal space (including the muscle and optic nerve), extraconal space or the eye ball; the features of the lesion (density, calcification and enhancement). CT is also useful to demonstrate the precise extension of the orbital lesion, the involvement of the adjacent para nasal sinuses and nasal cavity, the evidence of the bone erosion and intracranial extension which helps in the pre treatment evaluation and post treatment follow up. The main aim of our study was to characterize orbital tumors with respect to their location, density, enhancement, calcification and bony changes and to correlate the findings of computed tomography with histopathology/surgical findings where ever applicable. A prospective study was conducted between December 2013 to December 2015 on 51 patients with suspected orbital tumors. Patients were evaluated with computed tomography using Toshiba Activion 16 and findings were correlated with histopathology / surgical findings / clinical follow up where ever applicable. Fifty one patients with orbital masses were evaluated in this study. A female predominant affection was noted (21 males and 29 females). The various tumors we came across in this study were Cavernous and Capillary Haemangioma, Pseudotumour, Retinoblastoma, Optic nerve glioma, Meningioma, Lymphoma, Lacrimal gland tumor, Thyroid orbitopathy, Plexiform neurofibroma, Dermoid and Choroid melanoma.
