Patient Data

Age: 60 years
Gender: Female

An incidental finding of left renal vein thrombosis.

Evidence of a linear hypodense filling defect noted in the proximal aspect of the left renal vein (relative to the hilum of the left kidney). Evidence of narrowing of the proximal part of the left renal vein noted in between the aorta and the superior mesenteric artery. The angle between the aorta and the SMA is reduced. The left renal vein, prior to its drainage to the narrowed portion, appears slightly dilated

Hepatic hemangioma and cholelithiasis are noted.

Case Discussion

A case of a long venous filling defect highlighting the asymmetry of the anatomy of the renal veins.

With the increased use of CT, often for very general clinical indications, one needs to keep their eyes open for an array of incidental findings.

The incidental findings vary greatly in their significance.

Left renal vein thrombosis, with features as described. Clinical correlation to rule out any evidence of nutcracker syndrome is recommended.
