Solitary perihepatic splenosis mimicking liver lesion: a case report and literature review.
Hepatic splenosis, one type of manifestation of ectopic spleen tissue, is rarely reported. It cannot be distinguished from hepatic malignancies because of lack of significant radiological features. By means of this case report and 31 literature reviews, potential treatment modalities concerning clinical diagnostics, patient's management could be discussed.The report presents the case of a 33-year-old man with a liver lesion. Finally, after a mini-incision laparotomy, the lesion was resected and the diagnosis confirmed it as hepatic splenosis. A literature search for case reports published between January 1, 1900, and August 1, 2014, was performed on PubMed.Approximately 80% (27/34) of patients diagnosed with hepatic splenosis had a history of splenectomy. The mean time interval between splenectomy and hepatic splenosis detection was 25 (1.5-47) years. The median size of reported hepatic splenosis is 30  mm in diameter. Technetium-99m-labeled heat denatured red-blood-cells scintigraphy or superparamagnetic iron oxide-enhanced magnetic resonance imaging is now considered to be the optimal method of diagnosing splenosis.Hepatic splenosis requires no treatment in most cases. Operation should be performed if it is accompanied by hypersplenism in hematological diseases. When the diagnosis remains unclear, further biopsy or laparoscopy is recommended. If hepatic splenosis is confirmed, careful follow-up is beneficial.
