There are number of splenic lesions and anomalies:

Congenital anomalies

Mass lesions

Benign mass lesions

splenic cysts: see cystic lesions of the spleen
splenic haemangioma: commonest benign splenic lesion
splenic epidermoid cyst
splenic lymphangioma
splenic hamartoma
sclerosing angiomatoid nodular transformation (SANT) of the spleen: fibrosing variant of hamartoma ?
splenic abscess ~~- sonographically characterized~~: sonographically characterised by multiple “target” lesions

Indeterminate mass lesions

Littoral cell angioma of the spleen

Malignant mass lesions

lymphoma: commonest malignant tumour with splenic involvement ²
angiosarcoma of spleen: commonest primary malignant splenic tumour³
haemagiopericytoma of spleen
splenic metastases ~~- 50~~: 50% ~~melenoma~~malignant melanoma

Diffuse infiltrative processes

Usually manifests as splenomegaly

~~Some~~. Some can present as distinct lesions, e.g. granulomas

Other abnormalities

splenic rupture:
- traumatic: spleen is the most frequently injured ~~intraabdominal~~intra-abdominal organ in blunt trauma ²
- non traumatic
splenic infarction
splenosis
