Increased Uptake of 68Ga-DOTA-IBA in Lung NUT Carcinoma

Nuclear protein in testis gene rearrangement-associated midline carcinoma (NUT carcinoma) is a rare and highly invasive tumor. Here, we are reporting the image findings of a 38-year-old woman with lung NUT carcinoma. To evaluate the bone metastases, she underwent 68 Ga-labeled DOTA-ibandronic acid ( 68 Ga-DOTA-IBA) PET/CT examination. Surprisingly, the patient’s lung primary focus and subcutaneous nodule on the left side of the lower back region showed increased uptake.
