Quiste mesotelial primario esplénico como causa infrecuente de dispepsia: a propósito de un caso

Mesothelial cyst of the spleen mimicking a metastasis: a case report

“…Most primary splenic epithelial cysts are clinically silent and are often found incidentally or due to an abdominal mass or abdominal pain on imaging techniques, such as ultrasound (USG) or CT. 1 , 5 , 10 They are typically well-defined hypoechoic and hypodense lesion, with a thin or imperceptible wall, on USG and CT, respectively. 1 , 5 , 6 , 10 On magnetic resonance imaging, the cysts are hypointense on T1-weighted images and hyperintense on T2- weighted images, without reinforcement after contrast injection. 11 – 13 However, the signal intensity may vary depending on the contents of the cyst.…”

“… 14 Mesothelial cysts of the spleen have been described in the literature as unilocular with smooth and well-defined margins, without enhancing portions. 1 , 6 , 8 , 10 However, there are a few reports on multilocular mesothelial cysts, some of which were misdiagnosed as hydatid cysts due to their shape. 5 , 15 , 16 The imaging findings and clinical characteristics of previously reported cases of splenic mesothelial cysts are detailed in Table 1 .…”

“… 8 The accepted indications for treatment of splenic cysts include symptomatic cysts and cysts that are ≥ 5 cm due to a high risk of complications, such as rupture, bleeding and infection. 10 There are high rates of recurrence and complications with percutaneous treatment, such as aspiration and treatment with alcohol. 10 Surgery includes total or partial splenectomy, decapsulation (complete membrane extirpation) and fenestration (resection that puts the cavity of the cyst in contact with the peritoneum).…”
