Incidental FDG PET Finding of Situs Inversus: A Case Report

罕見正子攝影發現:完全內臟異位

摘要


完全性內臟異位(situs inversus totalis)是一種罕見的先天性變異,其內臟排列如同正常排列次序之鏡像。一位43歲男性因三個月來有右側頸部腫塊就診,之後證實爲鼻咽癌。病患接受氟-18-去氟葡萄糖正子攝影以分期。除了鼻咽部與右側頸部的高代謝病灶外,正子攝影顯示異位的心臟、肝臟、脾臟與胃臟,符合完全性內臟異位的診斷。胸部X光攝影與腹部超音波也顯示相符合的發現。

並列摘要


Situs inversus totalis is a rare congenital condition in which the viscera are transposed as a mirror of normal arrangement. We present a 43-year-old man with nasopharyngeal carcinoma who had right neck mass for 3 months. In addition to hypermetabolic lesions in the nasopharynx and right neck, the FDG-PET scan for initial staging showed transposed heart, liver, spleen and stomach, suggestive of situs inversus totalis. The chest X-ray film and abdominal sonography showed compatible findings.
