We report the case of a 65-year-old man with blunt abdominal trauma following a fall from a three-meter-high roof. Contrast-enhanced abdominal computed tomography (CT) obtained in early phase showed intense contrast enhancement in the urinary tract as dense as artery. This finding was considered characteristic of traumatic communication between artery and collecting system. In cases of blunt abdominal trauma, contrast-enhanced CT should be obtained in the early phase to diagnose this disorder. When the diagnosis is made, prompt treatment should be initiated.

Imaging findings of hepatic lesions of visceral larva migrans are reported. A 44-year-old man presented with chills, eruptions, marked leukocytosis (31,400/microlitter), and eosinophilia (eosinophil, 72%). Multiple liver nodules were detected as low-density lesions on computed tomography (CT). They were visualized as high signal intensity lesions on T2-weighted, and as low signal intensity lesions on T1-weighted magnetic resonance imaging (MRI). The patient was diagnosed as having visceral larva migrans due to Toxocara canis, by Toxocara immnoserological test. After antihelmintic therapy, multiple liver nodules disappeared on CT. We consider that the differential diagnosis of multiple liver nodules should include visceral larva migrans.
