Pre-treatment CT images of a 46-year-old woman with UTI-induced ovarian vein thrombosis. A coronal image (A) shows multifocal striated nephrogram (arrowhead) of the left kidney. An axial image (B) and oblique coronal images (C, D) show enhancing wall thickening of the left ureter (arrow) and hypoattenuated filling defect with enhancing wall of the left ovarian vein (arrowhead). Also, inflammatory fat infiltration around the ureter and ovarian vein is observed.

CT scan showed multifocal striated nephrogram of the left kidney (Figure 1A), suggesting acute pyelonephritis. A round, hypoattenuated filling defect with peripheral enhancing wall of the left ovarian vein and perivenous inflammatory fat infiltration were also observed (Figure 1B-D).
Follow-up CT images taken after 30 days. An axial image (A) and an oblique coronal image (B) show normalization of the left ureter (arrow) and recanalization of the left ovarian vein (arrowhead).
