Clinicopathological Correlation of Sinonasal Masses with Pre-operative Computed Tomography Findings

ABSTRACT

Aim of the Study The aim of the study was to study the clinical, radiological, and histopathological correlation of sinonasalmasses.Materials and Methods: This was a descriptive study conducted on 72 patients with sinonasal masses at Government T DMedical College, Alappuzha, over a period of 18 months from January 01, 2014, to June 30, 2015.Results: Age group was from 13 to 85 years with a male to female ratio of 1.31. Nasal obstruction was the most commonsymptom followed by nasal discharge and headache. Of the 72 cases, 59 belonged to the non-neoplastic group and 13 to theneoplastic group of sinonasal masses. Clinically, nasal polyp was the most common presentation. Sinonasal polyps (65.3%)formed the majority of the non-neoplastic lesions, vascular lesion (6.9%) was the most common benign neoplastic mass, andmalignancy was seen in 6.9% of cases. After clinical examination and computed tomography scan of the nose and paranasalsinuses, patients underwent surgery. Finally, clinical, radiological, and histopathology correlation of all the sinonasal masseswere done. The clinical diagnosis with computed tomography (CT) scan correlation was the same except in three cases andin one case with histopathology. Histopathology and CT scan result correlated well except in three cases. It was found thatthere was a significant association between the clinical, radiological, and histopathological diagnoses (P < 0.05) and that thesemodalities were complementary to each other. It was also possible to classify the lesions as non-neoplastic, neoplastic benign,and malignant using these modalities. This was important because even though initial presentation of these masses was similar,management of each of them varied significantly.Conclusion: Histopathology still remains the gold standard in the diagnosis of sinonasal masses, while CT scan is indispensablein studying the anatomical variants and providing the route map before and during endoscopic sinus surgeries.
