“…We report 2 instances of delayed renal artery pseudoaneurysm after renal artery intervention, adding to a small literature on late complications after renal artery intervention. Our first case has some similarities to one reported by Deitch et al, 4 whose patient developed a Staphylococcus aureus infection in a hemodialysis catheter after renal artery stenting. Three months later, she presented with severe back pain, elevated white cell count, and bacteremia; a renal artery pseudoaneurysm and juxtarenal aortic aneurysm were found, both presumably infected.…”

“…Less common causes include medial fibroplasia, pregnancy, and mesenchymal diseases such as neurofibromatosis and Ehlers-Danlos syndrome. Renal pseudoaneurysms are usually posttraumatic or inflammatory (eg, Behçet's disease, mycotic aneurysm) (35,36). The prevalence of renal artery aneurysms is reported to be 0.01%-0.1% (37).…”

Computed tomography (CT) plays an important role in evaluation and management of primary renovascular disease. Nonenhanced CT is useful for demonstrating renal hemorrhage, renal parenchymal or vascular calcifications, and masses. Contrast material-enhanced CT is essential to identify global or regional nephrographic abnormalities resulting from the vascular process (eg, renal infarcts, ischemia secondary to renal artery stenosis, arteriovenous communications). In addition, renal manifestations of a systemic disease (eg, vasculitis, thromboembolic disease) can be seen at CT. In trauma, occlusion of the main renal artery can be accurately diagnosed with contrast-enhanced CT. In cases of spontaneous renal hemorrhage without an apparent cause (eg, vasculitis, coagulopathy), a careful CT study should be performed to exclude renal cell carcinoma. The presence of fat in a hemorrhagic renal mass larger than 4 cm in diameter is characteristic of angiomyolipoma complicated by hemorrhage. Acute renal vein thrombosis appears as a clot in a distended renal vein, whereas renal vein retraction with collateral vessels is highly indicative of chronic thrombosis. Helical CT, especially with multiplanar two-dimensional and three-dimensional reconstruction following an intravenous injection of iodinated contrast material, has greatly improved our ability to directly image the proximal renal arteries and detect vascular lesions.

“…21 Another report demonstrated that a pseudoaneurysm was diagnosed at 30 mm, whereas a CT scan performed 2 months before was normal. 22 Given that ruptures have also been reported in smaller aneurysms if left untreated, it was decided that an intervention on the RAP would decrease the risk of ultimate rupture. 23 In our case, the size of the pseudoaneurysm was larger and was arising from a large posterior segmental renal artery.…”

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.
