MDCT of the Spleen: Splenic Calcifications


 Focal calcifications

Calcifications of the spleen are common and usually benign. Calcifications may be punctate, curvilinear or diffuse. Punctate splenic calcifications are typically the sequela of healed infection/inflammation. This is often due to fungal or granulomatous infection such as Candidiasis in immunocompromised hosts, or histoplasmosis in asymptomatic individuals.

Curvilinear calcifications

Curvilinear calcifications occur in the wall of cysts or cystic lesions. Evolution of an abscess may leave a peripherally calcified wall. Hydatid disease partially calcifies along its rim or may contain diffuse and punctate calcifications.

Peripheral calcification

Peripheral calcification develops in cystic lesions during evolution of hematomas, infarcts, and other processes leading to psuedocyst formation.

Diffuse calcifications

Diffuse calcification is most commonly present in sickle cell patients. The ongoing infarctions damages splenic tissue resulting in fibrosis, producing an atrophic calcified spleen. This processes is referred to as auto-splenectomy. A mimicker of diffuse calcification is Thoratrast, giving the spleen a diffuse high-density appearance on noncontrast CT.
