Littoral cell angioma (LCA) of the spleen is a rare vascular tumour. It was thought to be a benign and incidental lesion. Given the relative lack of specific symptom in many cases, these tumours are found incidentally during abdominal surgery during a non-related procedure. Clinical manifestation of a huge adnexal mass and the atypical appearance of splenomegaly, explains the often misguided diagnosis. To the best of our knowledge, there has been no case of incidental finding of LCA disguised as a huge ovarian cyst in Malaysia. We present a case report of a focal solitary LCA incidental finding after splenectomy.
