Hemangioma of the spleen: radiologic-pathologic correlation in ten cases.

Abstract

Ten cases of hemangioma of the spleen were reviewed. Plain abdominal radiographs and scintigrams are helpful in specifying the splenic location. Calcification, either central punctate or peripheral curvilinear, can be detected on radiographs or computed tomographic (CT) scans. The spectrum form solid to cystic change observed in the pathologic specimens is reflected in analogous patterns on CT scans and sonograms: predominantly solid mass; mass with cystic spaces. The angiographic findings are nonspecific. It is possible to suggest the diagnosis of hemangioma of the spleen when an asymptomatic patient presents with a discrete splenic mass, particularly if there is evidence of calcification and cystic change within the lesion.

Splenic hemangiosarcoma with massive calcification

“…Calcification can be seen in splenic hemangioma [13][14][15]. Splenic hemangiomas are usually small but may become large and distort the splenic contour [16]. Occasionally, hemangiosarcoma can resemble capillary hemangioma both clinically and radiologically, as seen in our case.…”

Sclerosing angiomatoid nodular transformation (SANT) of the spleen: Sonographic finding

“…2,3 According to autopsy data, the prevalence of splenic hemangioma ranges from 0.3-14% in adults aged between 29 and 50. 4 Other vascular lesions of the spleen include the rare hamartomas of the red pulp, also called splenomas, with a prevalence of 0.024-0.13%, 5 lymphangiomas, 6 littoral cell angiomas, 7 hemangiopericytomas 8 and hemangioendotheliomas, 9 and the inflammatory pseudotumor. 10 Primary malignant vascular tumors of the spleen are extremely rare, the most common within this group being the angiosarcoma.…”

Beyond hepatic hemangiomas: the diverse appearances of gastrointestinal and genitourinary hemangiomas

“…Also, diffuse involvement of the spleen, termed hemangiomatosis, can rarely occur and may cause anemia, thrombocytopenia, coagulopathies, and portal hypertension [24]. The average size reported for splenic hemangiomas is 2.4 cm [25], although lesions up to 17 cm have been reported [28].…”

“…On radiographs, focal calcifications in a punctate or curvilinear peripheral pattern may be seen, which represent calcium deposition in fibrous parts of the lesion [28]. If the lesion is particularly large, generalized splenomegaly may be apparent [28]. Imaging features on sonography are often nonspecific and variable [27].…”

“…Imaging features on sonography are often nonspecific and variable [27]. They may appear as complex cystic lesions or hyperechoic lesions [28] (Fig. 6).…”
