Solid pseudopapillary neoplasm of the small intestine with abdominal cavity metastasis

Published:February 14, 2023DOI:
      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.
