Solid pseudopapillary neoplasm of pancreas with distant metastasis during pregnancy: a diagnostic and treatment challenge.

Solid pseudopapillary neoplasms (SPNs) are rare pancreatic cystic neoplasms occurring predominantly in young women and diagnosis is often a challenge. This report describes the case of a 23-year-old primigravida who presented with abnormally elevated liver blood tests at 24 weeks of gestation. Imaging studies were suggestive of SPN with metastatic liver disease. A multidisciplinary team approach decided on a preterm caesarean delivery of a healthy female child at 36 weeks of gestation. Subsequently, a CT-guided biopsy was performed, with confirmation of SPN in the anatomopathological study. Subpartial pancreatectomy, partial gastrectomy, cholecystectomy, total splenectomy and partial hepatectomy were successfully performed. A 3-month control CT scan and positron emission tomography-CT studies revealed disease recurrence with pulmonary and liver metastatic disease. The patient was started on a palliative chemotherapy protocol with good tolerance. To our knowledge this is the first case of a SPN described in pregnancy with distant metastasis and disseminated recurrence after surgical treatment.
