Organizing Hematoma of the Maxillary Sinus Mimicking Malignancy Diagnosed by Fluorodeoxyglucose Positron-Emission Tomography (FDG PET/CT): A Case Report

Abstract

Organizing hematoma of the paranasal sinuses is a diagnostic dilemma clinically and radiographically, mimicking benign or malignant neoplastic processes. Although the diagnostic rate of this disease has increased as characteristic imaging findings are somewhat elucidated, endoscopic examination, preoperative biopsy, and computed tomography (CT) imaging do not give helpful information in differentiating these lesions from malignant neoplastic processes.
