Abstract

Background Renal artery pseudoaneurysm (RAP) is a rare renal vascular abnormality but a life-threatening condition that requires multiple imaging modalities for diagnosis and successful management. It can occur as a complication associated with a percutaneous renal biopsy procedure, renal surgery, and trauma. Asymptomatic spontaneous RAP is also a rare entity and not reported in literature.

Case Presentation A 28-year-old patient presented to the outpatient department for ultrasound of the breast for mastalgia and routine ultrasound of the abdomen. Ultrasound breast was normal; however, a cystic lesion with color uptake with a yin–yang pattern and to-and-fro spectral waveform was seen in the lower pole of left kidney suggesting a pseudoaneurysm. A computed tomography renal angiogram confirmed the diagnosis. The patient was completely asymptomatic with no history of any renal surgery or intervention or any trauma to the abdomen. Her general and systemic examinations were unremarkable. Digital subtraction angiography and coil embolization of the pseudoaneurysm were performed. Absent of flow in the lesion was demonstrated in postembolization angiography images and ultrasound images.

Conclusion RAP has always been described in patients after renal biopsy, surgery, interventions, or trauma. However, we present a case of asymptomatic spontaneous RAP, which was incidentally discovered and effectively treated with coil embolization.
