An Exceptional Presentation of Hutch Diverticulum on Bone Scintigraphy.

Abstract

Hutch diverticulum (HD) is a rare congenital condition characterized by the herniation of the bladder’s mucosa and submucosa through the detrusor muscle fibers, encountered more commonly in children. An association between HD and situs inversus totalis (SIT) in an elderly patient has not been reported previously in the literature. We present the case of a 70-year-old male referred for routine bone scintigraphy as part of staging for lung carcinoma; thoraco-abdomino-pelvic computed tomography confirmed the staging and revealed a total transposition of the thoracic and abdominal organs, confirming SIT. This case highlights the exceptional association of HD and SIT, which was discovered incidentally in an elderly patient during metastatic staging for lung cancer. It underscores the importance of careful interpretation of scintigraphic findings, particularly when unusual radiotracer uptake is observed.
