“…US is the initial imaging test of choice for diagnosing SVA, demonstrating either a saccular or fusiform, and hypo- or anechoic splenic vein dilatation 20,34–36. For extrahepatic portal vein aneurysms, which include SVAs (near its confluence with the superior mesenteric vein), a diameter that is greater than or equal to 2 cm is considered the diagnostic standard for cirrhotic patients, whereas it is at least 1.5 cm for the non-cirrhotic patients, based on the study by Doust and Pearce 37,38.…”

“…SVA will simultaneously enhance with the portal and superior mesenteric veins on CT, whereas they will appear as hypointense lesions on T1-weighted MRI 34. MRA is also a promising non-invasive tool that has replaced the conventional invasive angiography in the diagnosis of SVA, especially for patients undergoing surgery 39.…”

Vascular diseases of the spleen are relatively uncommon in the clinical practice. However, the reported incidence has been progressively increasing, probably due to advances in the imaging modalities used to detect them. This disease condition often presents with non-specific clinical manifestations, but can be associated with significant morbidity and mortality. This review article aims to provide updated clinical information on the different vascular diseases of the splenic vasculature—splenic vein thrombosis, splenic vein aneurysm, splenic artery aneurysm, splenic arteriovenous fistula, and spontaneous splenorenal shunt—in order to aid clinicians in early diagnosis and management.

Extrahepatic portal vein aneurysm is a rare disorder. From 1956 to 2008, we found only 43 published English-language reports, including 67 cases, using Pub Med. We report a case of a 77-year-old woman who had complaints of lower abdominal fullness and residual urine. We performed ultrasonography (US), which demonstrated a congenital extrahepatic portal vein aneurysm. She had no obvious symptoms of the extrahepatic portal vein aneurysm. She had undergone gastrectomy without blood transfusion for gastric ulcer more than 20 years ago. Physical examination revealed no abnormal findings. US revealed a 2.2 × 1.8 cm, round shaped hypoechogenic lesion at the hepatic hilum. Color Doppler US showed bidirectional colors due to circular flow within this lesion. 3D-CT and CT angiography demonstrated that the saccular aneurysm at the hepatic hilum was 3.0 cm in diameter and was enhanced equal to that of portal vein.Twenty-six months after the diagnosis, the aneurysm had not grown in size. Since our patient had no serious complaints or liver disease, surgical procedures had not been employed. US and 3D-CT are noninvasive diagnostic techniques and are helpful in the diagnosis and follow-up of extrahepatic portal vein aneurysms.

“…Due to their infrequency, there is no literature consensus on the etiology, appropriate management, and clinical and imaging follow-up of portal vein aneurysms. The greater utilization of abdominal cross-sectional imaging in recent years has led to a growing number of cases describing portal vein aneurysm [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ], and as such, proper handling of this lesion is increasingly relevant to both diagnostic and interventional radiologists. As such, we present the case of a 61-year-old patient with no history of liver disease and a portal vein aneurysm incidentally found on abdominal CT examination, and review the nature, significance, treatment strategies, and imaging surveillance of this vascular abnormality.…”

Portal vein aneurysms are rare vascular abnormalities, many of which are incidentally discovered on routine imaging studies. The etiology of portal venous aneurysms is poorly understood, and the management of these lesions is debatable. We report the case of a 61-year-old woman with extrahepatic portal vein aneurysm. We review the nature and significance of this abnormality and discuss appropriate clinical, imaging, and treatment approaches.
