Extrapelvic and extraperitoneal spread of recurrent stomach cancer: two case reports.

We report two cases of unusual combined extrapelvic and extraperitoneal extension of recurrent gastric adenocarcinoma and describe the imaging findings of the preferential anatomic pathway of disease spread. Extrapelvic and extraperitoneal extension of recurrent gastric adenocarcinoma is rare, and its symptoms may be vague and nonspecific. If patients with a surgical history of gastrointestinal neoplasm present with diffuse abdominal pain or painful swelling of the lower extremities, disease spread to the extrapelvic and extraperitoneal spaces should be suspected.
