A 36-year-old woman was hospitalized for a palpable 10-cm firm immobile mass in the
left hypogastrium. Laboratory tests revealed carcinoembryonic antigen (CEA) was 94.69
ng/ml (normal range: 0-6 ng/ml). An abdominal enhanced-computed tomography (CT) scan
showed a large solid-cystic mass, measuring 22.7 × 8.9 × 18.7 cm3, with heterogeneous gradual enhancement in the left intraperitoneal region (Fig. 1 A, B). Laparotomy was performed, and the tumor, whose capsule protruded out of the
small intestine, was excised entirely. No invasion or attachments to adjacent organs
were observed. Pathological analysis confirmed the diagnosis of an extrapancreatic
solid pseudopapillary neoplasm. She successfully recovered. She was hospitalized three
years later for a palpable abdominal mass again. An enhanced CT scan revealed a large
solid-cystic mass, measuring 11.0 × 8.9 × 7.8 cm3, with heterogeneous reinforcement in the right intraperitoneal region (Fig. 1 C, D). Laparotomy was repeated, the tumor adhered to the mesentery and transverse
colon, with poor mobility. Pathological findings suggested an extrapancreatic solid
pseudopapillary neoplasm. Postoperatively, the patient successfully recovered and
is currently in remission at her two-year follow-up.
