Endobronchial Chondroma: A Rare Case of Benign Tumor With Atypical High Standardized Uptake Value

Chondroma is a rare benign tumor of the cartilage and occurs in the tracheobronchial tree, either isolated or as part of the Carney triad. It has been sparsely described in the literature, and some were mislabeled as hamartomas. We herein report a case of a 63-year-old female who was initially treat...

Description
Summary:Chondroma is a rare benign tumor of the cartilage and occurs in the tracheobronchial tree, either isolated or as part of the Carney triad. It has been sparsely described in the literature, and some were mislabeled as hamartomas. We herein report a case of a 63-year-old female who was initially treated for community-acquired right middle lobe pneumonia. However, the patient's symptoms persisted warranting further workup, which confirmed the diagnosis of post-obstructive pneumonia. Whole-body positron emission tomography (PET) scan showed a hypermetabolic soft tissue lesion within the middle lobe bronchus, with a standardized uptake value (SUV) of 5.4, which is highly concerning for a primary or a secondary lesion. Since no distant lesions were identified, the patient underwent bronchial sleeve lobectomy of the right middle lobe under the assumption of localized disease. Pathology revealed chondroma, which had an unexpectedly high SUV on the PET scan; follow-up imaging denied any recurrence. Our case presents a rare entity of bronchial tumors with high SUV that presented with post-obstructive pneumonia. The patient's consent for writing this report was obtained.
