Abstract

A 63-year-old man with a history of right plantar malignant melanoma (T3bN0M0, IIb) developed multiple metastases in bilateral lungs 19 months after surgery. Subsequent F-FDG PET/CT revealed multiple pulmonary metastases with intense FDG uptake and detected a hypermetabolic lesion in the lateral wall of the left ventricle, which was considered to be a cardiac metastasis of malignant melanoma. This lesion was later confirmed in the dynamic myocardial perfusion MR. This case demonstrates the effectiveness of F-FDG PET/CT in detecting occult cardiac metastases of malignant melanoma.

摘要

一名63岁男性，有右足底恶性黑色素瘤病史（T3bN0M0，IIb期），术后19个月出现双肺多发转移。随后的F-FDG PET/CT显示多发肺转移灶伴FDG摄取增高，并在左心室侧壁检测到一个代谢增高的病灶，考虑为恶性黑色素瘤的心脏转移。该病灶后来在动态心肌灌注磁共振成像中得到证实。本病例证明了F-FDG PET/CT在检测恶性黑色素瘤隐匿性心脏转移方面的有效性。
