18F-FDG PET-CT in Cutaneous Metastases in Breast Carcinoma: An unusual presentation.

Cutaneous and subcutaneous metastases are an exceedingly rare presentation in various malignancies. These represent poor prognosis and disease progression. Early detection of such findings helps in changing the management plan.

"Superscan" on F18‑fluorodeoxyglucose Positron Emission Tomography - Computed Tomography [18‑F] FDG PET-CT.

"Superscan" features have been described in 18F FDG PET-CT (F18 fluorodeoxyglucose Positron Emission Tomography‑Computed Tomography) scan; characterized by significantly increased uptake in one or more organ systems resulting in absent or decreased uptake in the organs which normally show physiological uptake. The importance of the awareness has evolved over the years in order to avoid false interpretation of scan findings as well as in determination of a high tumour burden. We present images of three patients who underwent 18F FDG PET-CT scan showing findings consistent with FDG PET-CT superscan.

Hypermetabolic Sister Mary Joseph's nodule in pancreatic carcinoma.

Metastasis to umbilicus is often defined as Sister Mary Joseph's (SMJ) nodule. These nodules may be a manifestation of various underlying malignancies, about 50% arising from abdominopelvic cavity most frequently from the gastrointestinal tract. Pancreatic cancer is the predisposing cause in only about 6% of cases and the most common histopathology is adenocarcinomas.

Incidental findings on a DXA scan: the unattended innocents.

Dual energy X-ray Absorptiometry (DXA) scan is the gold standard for assessing and monitoring bone mineral density. Clear guidelines are given by ISCD and other societies as to the appropriate use of this modality. However, as with other imaging modalities, a DXA scan can reveal incidental findings that must be mentioned in the report.
