Solitary Scapular Metastasis as the First Presentation of Prostate Adenocarcinoma Identified on 99mTc-MDP SPECT/CT.

ABSTRACT: Metastases of prostate carcinoma in the skeleton are usually multiple. Solitary metastasis in appendicular skeleton is extremely rare. We present bone scan findings of solitary scapular metastasis from prostate adenocarcinoma as the initial presentation of his malignancy in a 62-year-old man. The 99mTc-MDP SPECT/CT demonstrated intense activity in the coracoid process of left scapula, whereas the tracer uptakes in other bones were not typical of metastases. The subsequent pathological results of the punctured left scapula confirmed as metastasis from prostate adenocarcinoma.
