RESUMEN
A 72-year-old Japanese woman was admitted because of vomiting and abdominal pain. An enhanced computed tomography scan showed a small intestinal obstruction due to ileal wall thickening and multiple liver metastases. Her serum alpha-fetoprotein (AFP) level was high at 1671.9ng/ml. An ileocecal resection was performed. The histological diagnosis was AFP-producing small intestinal cancer resembling the primitive gut epithelium of a fetus. The present case suggested that even intestinal cancer could produce AFP.

We present the gray-scale ultrasonography (GSUS), power Doppler ultrasonography (PDUS), abdominal computed tomography (CT), and magnetic resonance imaging (MRI) findings for a case of splenic hamartoma in a 27-year-old man, showing a phi 50 mm homogeneous, iso- and hypo-echoic splenic mass with evidence of a small plural cystic lesion. This splenic hamartoma showed increased vascularity on power Doppler sonograms. PDUS showed multiple circular blood flow signals inside the mass (i.e. a basket pattern), which was consistent with the small plural cystic lesion shown by GSUS. Spectral analysis also confirmed arterial and venous flow. CT scans showed that the mass had low-density relative to the normal spleen and MRI showed that the mass was isodense, relative to the normal spleen. Therefore, CT and MRI are not useful for the diagnosis of splenic hamartoma. Ultrasonography can be used to diagnose splenic hamartoma without administration of a contrast material and therefore is an indispensable method for the diagnosis of splenic hamartoma.
