Congenital absence of the portal vein complicating hepatic tumors.
Congenital absence of the portal vein (CAPV) is a rare malformation that is often accompanied by other anomalies such as cardiac and skeletal malformations and/or hepatic tumors. We describe here a case of CAPV complicating hepatic tumors in a 16-year-old Japanese girl. Abdominal ultrasonography revealed a hyperechoic tumor in the liver and dilatation of the portal vein that appeared to be connected directly with the inferior vena cava. Subsequent abdominal computed tomography (CT) revealed tumors and magnetic resonance angiography confirmed that the portal vein entered directly into the inferior vena cava just above the liver. In addition, there was absence of the right portal vein and the left intrahepatic branch except for the presence of left portal vein only within the porta hepatis. These findings led to a diagnosis of CAPV complicated hepatic tumors. Careful monitoring of these hepatic tumors is ongoing due to the possibility of malignant transformation.

Severe strongyloidiasis complicated by meningitis and hydrocephalus in an HTLV-1 carrier with increased proviral load.
We report a 47-year-old Japanese man who was a human T-cell leukemia virus type 1 (HTLV-1) carrier with strongyloidiasis, and who was born in an area endemic for both Strongyloides stercoralis ( S. stercoralis) and HTLV-1. He presented with edema of both legs. Laboratory examination on admission revealed hypoalbuminemia, and S. stercoralis rhabditiform larvae were found by stool microscopy. Purulent meningitis, which was suspected to be due to disseminated strongyloidiasis, developed during the first and second treatment for S. stercoralis infection. After the meningitis was alleviated, hydrocephalus with gait disturbance developed, and these features were attenuated by a ventriculo-peritoneal shunt. Impaired immunity and increased HTLV-1 proviral load, with an increased titer of HTLV-1 antibody, were observed in this patient. These results suggest that HTLV-1 proviral load and/or antibody titer of HTLV-1 can be used for the identification of carriers who are at increased risk of developing severe strongyloidiasis among those patients who are infected with both S. stercoralis and HTLV-1.
