Inferior Vena Cava Aneurysm in an Infant Presenting With a Renal Mass

Abstract

Aneurysm of the inferior vena cava is a rare finding in the pediatric population. We report the case of a 5-month-old infant presenting with anemia, hypertension, and dehydration in the emergency room. A renal mass was found with ultrasound and MRI and a renal tumor was first considered. Histopathologic review of the surgical specimen led to the diagnosis of aneurysmal dilatation of the vena cava.

Isolated inferior vena cava aneurysm: a case report

“…16 Unzueta-Roch et al reported a case of IVC aneurysm mimicking right renal mass in a five-month old infant which was managed by surgery. 17 Similar cases of surgical management of IVC aneurysms have been reported by Deshpande et al 18 and Lochbuehler et al 19 Tansel et al reported another case of IVC aneurysm in a 14-year old boy who was followed-up periodically without surgery. 20…”

Multiple inferior vena cava aneurysms mimic a retroperitoneal tumor: a case report

“…Because the symptoms are non-specific, imaging tests like ultrasonography, contrast-enhanced CT, magnetic resonance imaging and cavography play a vital role in the diagnosis of IVC aneurysms [ 6 ]. However, some IVC aneurysms could be confused with retroperitoneal tumors, such as renal carcinoma, sarcomas, enlarged lymph nodes, neurogenic tumors and primary IVC tumors [ 7 – 9 ], especially when the lumen of the aneurysm is completely thrombosed [ 8 ]. Therefore, comprehensive consideration of various imaging tests results can increase the accuracy of diagnosis.…”
