Are splenic hemangiomas common?

Splenic hemangioma is a rare disorder but remains the most common benign neoplasm of the spleen. It often has a latent clinical picture; however, spontaneous rupture has been reported to occur in as many as 25% of this patient population.

What is hemangioma of the spleen?

Splenic hemangiomas are rare lesions, but they are the most common benign primary tumor of the spleen. In addition to hematopoietic disorders, the spleen can be involved by other processes including nonhematopoietic lesions such as hamartomas, pseudotumors, metastatic tumors, cysts, and vascular tumors.

What causes lesions in the spleen?

Etiologies for multifocal splenic lesions include infectious and inflammatory processes, primary vascular and lymphoid neoplasms, metastatic disease, vascular processes, and systemic diseases. There is often overlap in the imaging appearance alone, so the clinical setting is very helpful in differential diagnosis.

Can spleen hemangioma cause pain?

Most of the patients are asymptomatic, rest of the patients presenting with pain and a lump in the abdomen. Majority of the splenic hemangiomas (SH) remain small in size rarely reaching a large size. Small hemangiomas can be observed safely but large, symptomatic hemangiomas can be treated by splenectomy.

What is splenic cyst?

Splenic epithelial cysts, also known as splenic epidermoid cysts or primary splenic cysts, are unilocular fluid lesions with thin and smooth walls and no enhancement. They represent ~20% of cysts found in the spleen, and are usually an innocuous incidental imaging finding.

What is a hemangioma on the spine?

Spinal hemangiomas are benign tumors that are most commonly seen in the mid-back (thoracic) and lower back (lumbar). Hemangiomas most often appear in adults between the ages of 30 and 50. They are very common and occur in approximately 10 percent of the world’s population. Most cases show no symptoms.

Are splenic lesions cancerous?

The majority of such solid splenic nodules and masses are benign, with hemangioma being the most frequent diagnosis (8,9). However, CT imaging characteristics of benign and malignant splenic masses often overlap, making definitive differentiation difficult (8,10).

What is splenic lesion?

A splenic hamartoma is typically a well-defined, solid, nodular lesion that compresses the surrounding splenic tissue. In some cases, it is cystic or contains calcifications.

Do splenic cysts go away?

Small asymptomatic splenic cysts are common and do not require treatment or follow-up. Axial CECT demonstrates a splenic cyst with a thick peripheral rim of calcification in a patient with a prior history of trauma. Splenic cysts often result from prior trauma or splenic hematoma.

Can a splenic lesion be seen as a hemangioma?

Small splenic lesions, which meet the radiologic criteria for hemangiomas, may be safely observed. Fingerprint Dive into the research topics of ‘Hemangioma of the Spleen: Presentation, Diagnosis, and Management’.

How are calcified splenic lesions used in differential diagnosis?

Whereas most calcified splenic lesions are presumed to be sequel-ae of prior granulomatous infection, there is a broader differential diagnosis for these lesions. An algorithmic approach to splenic lesions according to their characteristic calcification patterns can therefore narrow the differential diagnosis and help guide management.

Which is a pathological differential diagnosis of splenic hamartoma?

The pathological differential diagnosis includes hemangioma, Littoral cell angioma, lymphangioma, hemangioendothelioma, sclerosing angiomatoid nodular transformation (see terminology), angiosarcoma.

When to use pattern recognition for splenic lesions?

In cases in which splenic lesions on CT may not have a characteristic pattern of attenuation or enhancement, the morphologic features and pattern of calcifications can help the differential diagnosis [ 2 ].
