[edit] Discussion of Littoral cell angioma

  • Littoral cell angioma of the spleen is a rare vascular tumor
  • First described in 1991.
  • Biologic behavior has not been firmly established.
  • Littoral cell angiomas may occur at any age and have no gender predilection.
  • Typically, patients with littoral cell angioma are found to have a splenic abnormality when they are being evaluated for laboratory evidence of anemia or thrombocytopenia.
  • Splenomegaly is almost always present.
  • An association between littoral cell angioma and other malignancies, including colorectal, renal, and pancreatic adenocarcinoma and meningioma, has been described.
  • In most patients, because symptomatic hematologic problems are present and because the imaging findings are nonspecific, splenectomy is typically performed for definitive evaluation and treatment.

[edit] Imaging Findings for Littoral cell angioma

  • Littoral cell angioma should be considered in the differential diagnosis of multiple splenic lesions in patients with evidence of hypersplenism.
  • Sonograms, CT scans, and MR images usually demonstrate splenomegaly and multiple lesions of similar size and appearance.
