Spontaneous nontraumatic intrasplenic pseudoaneurysm: Causes, sonographic diagnosis, and prognosis

“…In reported cases, intrasplenic pseudoaneurysms seem to be associated with a risk of secondary delayed splenic rupture; therefore, the diagnosis of intrasplenic pseudoaneurysm is an indication for splenectomy, 5,6,8 which was performed in 3 of our patients.…”

“…4,5 Sonography is a valid and reliable method for detecting focal splenic lesions, 4 and color Doppler sonography (CDS) permits the identification of vascular pathologic conditions such as pseudoaneurysms. 1,2,6 We undertook this study to describe the incidence, causes, sonographic features, and prognosis of NTISP in patients with spontaneous splenic rupture seen in our clinic.…”

Spontaneous Rupture of an Intrasplenic Aneurysm After Pancreaticoduodenectomy for Pancreatic Ductal Adenocarcinoma

“…Spontaneous rupture of intrasplenic aneurysm is extremely rare, mostly occurring as a complication of malignant diseases, infectious diseases, or portal hypertension (2). In our case, as also mentioned by Gupta et al, there were several risk factors present that could have caused rupture of an aneurysm besides enoxaparin, including pancreatic adenocarcinoma, chemoradiotherapy, and surgical stress (3).…”

Intrasplenic Arterial Aneurysms during Pregnancy

“…Nontraumatic intrasplenic pseudoaneurysms (NTISPs) are rare complications of splenic infarction, infiltration by malignant systemic disorders, infectious process, chronic pancreatitis, and arteritis [19, 20]; they are known to cause spontaneous nontraumatic splenic rupture with hemoperitoneum and they can be single or multiple, are more common in men, and are extremely fragile.…”

“…In case they develop as a complication of nonoperative management of splenic trauma, they can be diagnosed during follow-up prior to rupture with the use of US, colour Doppler US, or CT scan screening [13]. NTISPs may present with splenic rupture or with splenic infarction as a result of thrombosis of the pseudoaneurysms [19]. …”
