Detection of Esophageal Tuberculosis, a Rare Cause of Abdominal Pain, on ¹⁸F-FDG PET/CT

(A) ¹⁸F-FDG PET maximum-intensity projection shows abnormal hot spot in midline lower thoracic region. (B–G) Corresponding transaxial (top) and sagittal (bottom) contrast-enhanced CT (B and E), PET (C and F), and PET/CT (D and G) images reveal ¹⁸F-FDG–avid (SUV_max, 9.8) heterogeneously enhancing soft-tissue-density lesion (∼1.3 × 1.2 × 1.5 cm) in posterior wall of lower thoracic esophagus (arrowheads). Lesion was causing mild narrowing of esophageal lumen.
