We present a case of a 66-year-old female patient with thyroid papillary carcinoma. On the fluorine-18 fluorodeoxyglucose (F18-FDG) positron emission tomography/computed tomography (PET/CT) performed for thyroglobulin elevation accompanied by negative radioiodine whole-body scan, there was an intense 18F-FDG uptake in the polypoid soft tissue invading the tracheal cartilage and extending into the lumen. Dedifferentiated tumor with high metabolic rate can be easily detected by 18F-FDG PET/CT.

    ABSTRACT: Endotracheal metastasis is a rare situation, usually associated with malignancies of breast and gastrointestinal tract, specially colon. Papillary carcinoma of thyroid commonly disseminates through lymphatic channels and tracheal involvement through vascular route is rarely reported. Here, we report a case of tracheal metastasis from papillary carcinoma of thyroid. The patient responded to external beam radiation therapy with cobalt 60 beams in a dose of 44 Gy followed by a 16 Gy boost. The patient is under followup and is presently asymptomatic. This paper adds to the repertoire of evidence in treatment of endotracheal metastasis.

    ABSTRACT: Endotracheal infiltration by lymphoma is uncommon. We present 2 cases of endotracheal infiltration by non-Hodgkin lymphoma. One case had a solitary lesion in the middle trachea. Bronchoscopic biopsy of the lesion revealed diffuse large B-cell lymphoma. The tumor showed focal FDG uptake with SUVmax of 15. The other case had diffuse endotracheal lesions. Bronchoscopic biopsy revealed diffuse submucosal infiltration by natural killer/T-cell lymphoma. The thickened trachea showed diffuse FDG uptake with SUVmax of 8.4. These 2 cases indicate lymphoma should be included in the differential diagnosis of focal or diffuse endotracheal FDG accumulation.
