Role of SPECT/CT in sentinel lymph node detection in patients with breast cancer.

Aim: The purpose of this study was to conduct a systematic review of the published literature to assess the role (indications, advantages, and limitations) of SPECT/CT for the detection of sentinel lymph node (SLN) in breast cancer.

Methods: The authors searched PubMed for published literature in English addressing this topic.

Results: Eleven studies, published since 2006, focused on the role and value of SPECT/CT for SLN detection (SLND).

Radioiodine accumulation in a giant ovarian cystadenofibroma detected incidentally by 131-I whole body scans.

Ovarian cystadenofibroma is a relatively rare tumor; it is usually asymptomatic and is found incidentally. We present the case of a 24-year-old female patient, who had undergone total thyroidectomy for thyroid papillary carcinoma, with an asymptomatic giant cystadenofibroma, incidentally discovered by diagnostic (131)I-SPECT/CT WBSs. We summarize the clinical history, imaging data, and histopathological study on a rare case of radioiodine accumulation in cystadenofibroma, and we discuss the mechanism of uptake of radioiodine in this case.
