Vo QD Monnard E Hoogewoud HM 2013 We report the case of a patient with a palpable mass and abdominal pain in the left upper quadrant. A physical examination revealed tenderness in this region. An ultrasound performed initially showed a large cystic structure. A CT examination revealed a large cyst originating in the spleen with loculations in its upper part and focal calcification in the wall. On MRI, the cystic mass showed high signal on T1-weighted and T2-weighted images. The carbohydrate antigen 19-9 (CA 19-9) was measured at 88 U/ml (standard <37.1 mUI/l). According to the imaging examinations and laboratory tests performed, it was impossible to determine if the splenic cyst was parasitic or non-parasitic. Given the most important risks of complications encountered in parasitic cysts, it was decided to treat this splenic cyst as a parasitic cyst. For this reason, an elective laparoscopic splenectomy with preoperative embolisation of the splenic artery was performed. The histological diagnosis was a primary epidermoid splenic cyst with inner lining epithelial cells. application/pdf https://sonar.ch/global/documents/89561 eng info:eu-repo/semantics/altIdentifier/doi/10.1136/bcr-2013-009707 info:eu-repo/semantics/altIdentifier/pmid/23667225 info:eu-repo/semantics/openAccess BMJ case reports. - 2013 Abdominal Pain Adolescent Animals CA-19-9 Antigen Calcinosis Epidermal Cyst Epithelial Cells Female Humans Parasites Spleen Splenectomy Splenic Artery Splenic Diseases Epidermoid cyst of the spleen. http://purl.org/coar/resource_type/c_6501
