HERNANDEZ BENEDICTO, René et al. Malignant insulinoma with splenic metastasis: an infrequent observation. AMC [online]. 2009, vol.13, n.4. ISSN 1025-0255.

The second case of malignant insulinoma reported in our country is presented. A 41-years female patient is admitted with the predominant clinical picture of neuroglycopenic manifestations due to severe hypoglycemias mimicking seizures and psychiatric disorders. Positive results are obtained in tests of tolbutamide, glucagon, intellectual performance and prolonged fasting. In this patient, the insulinoma is not revealed through ultrasonography and CT scan. She is undergone a distal pancreatectomy with splenectomy, procedures that demonstrate the insulinoma and splenic metastasis. After surgery, the patient is free of neurologic symptoms.

Palabras clave : malignant insulinoma; splenic metastasis; neuroglycopenic symptoms.
