Radioiodine-Avid Paravertebral Bronchogenic Cyst Mimicking Neurofibroma: A Diagnostic Pitfall.

Abstract

ABSTRACT:

The whole-body postablation scan of a 38-year-old man, with history of papillary thyroid cancer, revealed a focus of intense 131I accumulation about the lower thoracic vertebrae. SPECT/CT revealing a soft tissue lesion adjacent the T9 to T10 vertebrae, which was reported as neurofibroma on the subsequently performed MRI. However, the lesion was confirmed as a bronchogenic cyst on biopsy. Respecting that unlike neurofibroma, immunohistochemistry studies have confirmed Na-I symporter expression in bronchogenic epithelium; our case highlights that, although rare, paravertebral bronchogenic cysts should be considered in differential diagnosis of radioiodine-avid paravertebral lesions.
