Bottom Line: PSH is often asymptomatic and presents as a solitary or multiple pulmonary nodules on radiologic imaging studies.The authors describe an interesting but uncommonly encountered cause of false positive FDG PET scan in the thorax in a 25-year-old woman, a known case of arteriovenous malformation of oral cavity who underwent embolization and presented with incidental detection of bilateral lung nodules.She is asymptomatic and is on follow-up.

ABSTRACT
Pulmonary sclerosing hemangioma (PSH), or the alternative name of "sclerosing pneumocytoma," is a rare benign neoplasm. PSH is often asymptomatic and presents as a solitary or multiple pulmonary nodules on radiologic imaging studies. Few articles have been reported to describe the fluorodeoxyglucose positron emission tomography (FDG PET) findings about PSH. The authors describe an interesting but uncommonly encountered cause of false positive FDG PET scan in the thorax in a 25-year-old woman, a known case of arteriovenous malformation of oral cavity who underwent embolization and presented with incidental detection of bilateral lung nodules. She is asymptomatic and is on follow-up.

Mentions: The present case report is about a 25-year-old female patient, already a known case of Arteriovenous malformation of oral cavity and she underwent embolization of the lesion, presented with incidental detection of bilateral multiple pulmonary nodules on CT scan. CT showed round or oval pulmonary nodules, with smooth margin associated with marked enhancement. She was referred for whole body positron emission tomography/computed tomography (PET/CT) for detection of primary site and to differentiate between benign and malignant nodules. PET/CT showed an intense uptake in the bilateral pulmonary nodules [Figure 1] with largest nodule located in right lower lobe with a standardized uptake value (SUVmax) of 10.5. Some of the lesions did not show FDG uptake patient underwent minithoracotomy and wedge biopsy of the lesion [Figure 2] and biopsy confirmed PSH [Figure 3]. A diagnosis of bilateral multiple PSH was made and she was advised follow-up.
