A variety of non-neoplastic and neoplastic conditions involving the nasal cavity, paranasal sinuses (PNS), and nasopharynx are commonly encountered in clinical practice. The objectives of the study were to identify various pathological conditions that present with sinus or nasal mass, to understand their varied clinical behavior, to know the distribution of various lesions among the different age and sex groups, and to study the management of sinonasal masses and its outcome on follow-up. A prospective study was carried out from September 2013 to August 2015, in the Otorhinolaryngology Department of Hi-Tech Medical College & Hospital, Bhubaneswar, Odisha. The study included patients of any age and sex presenting with nasal symptoms (suspected of a sinonasal mass). This study included all cases seen during the above duration. Complete history was taken and full clinical examination was carried out. Majority of the patients with sinonasal masses were in the age group 41-50 years. Male:female ratio was about 1.2:1. Nasal obstruction was the most common presentation. Most common non-neoplastic lesion was rhinosporidosis and most common benign lesion was hemangioma. Most common malignant lesion was maxillary carcinoma. The presenting features of all sinonasal lesions may be indistinguishable and pose diagnostic dilemma. Correlation of clinical, radiologic, and most importantly pathologic modalities is of utmost importance for accurate diagnosis.

ARTICLE INFO ABSTRACT The purpose of the study is to establish the role of magnetic resonance imaging (MRI) in the evaluation of various causes of compressive myelopathy, characterization of compressive lesions and to classify the lesions based on location into extradural / intradural compartments. Seventy patients who were clinically suspected to have compressive myelopathy were subjected for MRI. In this study, extradural compression due to degenerative changes (54.3%) was found to be the most common cause of compressive myelopathy, followed by infectious spondylitis (14.3%), post traumatic compressive myelopathy (12.8%), primary neoplasms & metastases (12.8%) and other causes (5.8%). There were 6 cases of intradural extramedullary pathology, remainder (64 cases) of the cases showed extradural location of pathology. MRI detected cord changes in 97% of cases with cord compression and also assessed the integrity of spinal cord, intervertebral discs and ligament after acute spinal trauma. MRI is very definitive, sensitive, accurate, though costly but very specific, non-invasive, radiation free modality for evaluation of compressive myelopathy.
