Bottom Line: The clinical, radiological, and histopathologic findings of the patient are presented.In this report, we have presented (18)FDG-PET findings of organized hematoma of the maxillary sinus (OHMS) that showed an increased FDG uptake in the peripheral rim of the mass with central photopenia.Careful interpretation of metabolic (FDG-PET/CT) and anatomic (CT and MRI) images should be performed to accurately characterize the expansile lesion of the maxillary sinus in order to increase specificity and reduce equivocal findings significantly.

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. A 55-year-old man presented with a 4-month history of recurrent nasal bleeding. He also complained of a left-sided nasal obstruction. CT findings were highly suggestive of a malignant tumor of the maxillary sinus. However, based on fluorodeoxyglucose F(18) positron-emission tomography (PET/CT) and magnetic resonance imaging (MRI), the provisional diagnosis of benign tumor rather than malignancy was made. Complete resection of the mass was achieved by simple transnasal endoscopic surgery using the Caldwell-Luc approach. Organizing hematoma of the maxillary sinus was diagnosed by histopathologic evaluation. The clinical, radiological, and histopathologic findings of the patient are presented. In this report, we have presented (18)FDG-PET findings of organized hematoma of the maxillary sinus (OHMS) that showed an increased FDG uptake in the peripheral rim of the mass with central photopenia. To our knowledge, this is the first case report in the literature reporting FDG-PET/CT findings of OHMS. Careful interpretation of metabolic (FDG-PET/CT) and anatomic (CT and MRI) images should be performed to accurately characterize the expansile lesion of the maxillary sinus in order to increase specificity and reduce equivocal findings significantly.

Integrated 18F-FDG-PET/CT images show moderate uptake only at the peripheral rim (black arrows) of the mass with negative FDG uptake in the central portion (asterisk). The maximum standardized uptake value (SUVmax) of this lesion is 3.80. Other signs of abnormal uptake suggesting a malignant lesion are not observed.
