Abstract

An alpha-fetoprotein-producing gastric cancer is rare, making up only about 3% of all gastric cancers. Further, gastric cancer with metastasis to the scrotum via a transperitoneal route is extremely rare. We report a case of metastatic scrotal mass in a 68-year-old man who had undergone a subtotal gastrectomy and gastroduodenostomy due to signet ring cell type gastric cancer with a description focusing on the radiologic findings.

Figure

• 

  Fig. 1 Ultrasonography of right scrotum. Multilobulated and heterogeneously hyperechoic masses (M) are noted in the posterolateral aspect of testis (T) with hydrocele in the right scrotum.

• 

  Fig. 2 Pelvic CT scan of right scrotum. A. Axial CT scan image shows the lobulated and contrast-enhanced masses (arrows) along the posterolateral inner wall of right scrotum with hydrocele and congested veins. B. Coronal reformat CT image shows the lobulated enhancing mass in the right scrotum with large amount of hydrocele. A small enhancing nodule (arrow) is also seen in the distal portion of right spermatic canal, indicating metastatic seeding nodule from peritoneal carcinomatosis.

• 

  Fig. 3 Abdomen CT scan of the liver. About 3 cm size lobulated low density mass is seen in right posterior perihepatic space with peritoneal nodules (arrow) and small amount of ascites.

• 

  Fig. 4 Follow-up pelvic CT scan after 8 months. Axial CT scan image shows near complete disappearance of previously noted extratesticular masses in the right scrotum with normal appearance of testis (T), minimal fluid collection and intrascrotal peripheral enhancement.
