EVALUATION OF PAROTID GLAND PATHOLOGY BY ULTRASONOGRAPHY AND COMPUTED TOMOGRAPHY IMAGING
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2019, Vol 8, Issue 10
Abstract
BACKGROUND Ultrasonography (USG) is the first diagnostic procedure to evaluate suspected parotid lesions. USG is capable of differentiating benign and malignant parotid masses. Computed Tomography (CT) is essential for confirmation of diagnosis and preoperative workup in staging of malignancy. Aims and Objectives: 1. To evaluate role of ultrasound and computed tomography in imaging of different parotid gland pathology. 2. To know role of ultrasound and computed tomography imaging in the identification of different parotid gland tumours. MATERIALS AND METHODS A retrospective descriptive study of 80 patients was done. Study group consists of patients with parotid gland enlargement, who underwent ultrasonography with or without CT scan. Patients with normal parotid gland on USG are not included in our study. Out of 80 patients of ultrasonography having parotid gland enlargement, 36 patients underwent CT scan. RESULTS Out of 80 patients, most common pathology was infective or inflammatory origin and 98% sensitivity and specificity was seen. Second most common pathology was benign neoplasm where sensitivity was 88%, while specificity was 84%. 43 patientswere found to have infective or inflammatory aetiology. 31 patients had neoplasm, among them, 22 patients had benign masses and 8 patients had primary malignant masses and 1 patient had intraparotid metastatic lymph node. Only 1 patient had congenital vascular pathology. In malignant masses, sensitivity and specificity were 80%. CONCLUSION Ultrasonography is the basic modality for parotid gland pathology and CT scan is the investigation of choice for parotid masses to confirm benign nature by the pattern of vascular enhancement and staging of malignancies of parotid gland.
