Splenic cyst is developmental in origin.

True nonparasitic splenic cyst, also called congenital cyst and epidermoid cyst, is defined by the presence of an inner endotheial lining.

• Inflammatory (abscesses, hydatid cyst)
• Vascular (infarction], peliosis)
• Posttraumatic (hematoma, false cyst)
• Neoplastic (hemangioma, lymphangioma, lymphoma, metastasis)

• Anechoic well-defined, round mass.

• CT typically shows a large, low-attenuation,unilocular mass with imperceptible walls;
• HU are in the range of that of water.
• No enhancement is seen after the administration of contrast material

• Magnetic resonance (MR) images show a well-defined, round mass.
• On T2-weighted images, the mass has markedly high signal intensity, a characteristic finding of a cyst.
