脾臟囊腫並不是常見之疾病,比其他腹腔內器官囊腫要少見,但比脾臟腫瘤要多見。自1829年Andral首次於剖檢中發現第一例脾臟非寄生蟲性囊腫,至今約有600例報告。 脾臟囊腫以有無內襯表皮分為真性或偽性囊腫,寄生蟲性脾囊腫佔全部脾囊腫之三分之二。先天性真性脾囊腫却只佔百分之十,先天性脾囊腫中以血管瘤佔最多,以皮樣囊腫為最少,而脾臟囊性淋巴管瘤在兩者之間。 我們經驗有一位67歲榮民,因其他病情住院,而腹部超音波偶然發現貏臟有三個高回音之腫塊,經電腦斷層掃描、核酸掃描、血管攝影、皮下穿刺細胞學檢查均無法診斷出病情,最後經開刀後證實是脾臟囊性淋巴管瘤。特將此病例提出報告以供參考,並討論每項檢查之結果及回顧文獻以討論之。
Nonparasitic splanic cyst is not a common clinical and pathologic entity. In this study, a 67 year-old male patient was found to have 3 hyperechoic masses in the spleen incidentally during a routine examination of abdomen by sonography. A correct diagnosis of splanic cyst could not be made preoperatively using either ultrasound, Tc-99 phytate liver spleen scintigraphy, heat-damaged red blood cell splanic scintigraphy, computed tomography, or angiography and percutaneous fine needle aspiration cytology. Discussions of failures of each investigation and review of splanic cysts will be presented.
