Location
Imaging findings (US, CT, MRI, MRCP)
Lewis et al[9], 1988Left lobe (5), right lobe (8), porta hepatis (1), central (2)US demonstrated fluid-filled lesions with internal septation and nodularity consistent with the papillary infoldings. CT revealed a smooth, thick walled cyst with thin internal septations
Stoupis et al[3], 1994Right lobeCT showed a large septate, hypoattenuating mass with enhancement of the septations. MRI showed multilocular lesion with different signal intensities in the locules
Hara et al[11], 2001Left lobeCT demonstrated a multiple low density mass. MRI showed multilocular cysts, with homogeneous signals on T1WI and T2WI
Kazama et al[6], 2005Right lobeCT demonstrated a giant, well-circumscribed, low-density mass with internal septa
Lewin et al[15], 2006Left lobeMRI revealed a homogeneous cystic lesion in the six BCAs. Three BCAs showed a hypointensity on T1WI and an isointensity in the other three. A fluid/fluid level consistent with internal hemorrhage was found in one BCA. MRCP showed ductal dilatation upstream to cystic lesion in two BCAs
Yu et al[8], 2008Left lobeMRI showed a cystic mass in the left hepatic lobe. MRCP showed diffuse dilatation of the biliary tree with different signals in the bile ducts
Left lobeCT revealed a large cystic mass with septations and multiple papillary projections
Delis et al[5], 2008Left lobe (3), right lobe (1)US revealed various sizes of cysts with septations and infolding projections originating from the cystic wall. CT revealed cysts with internal septations and mural nodules with contrast enhancement
Romagnoli et al[13], 2011Segments 4 and 8CT and MRI revealed a cystic mass with septations in its caudal portion, lying on the Glissonian bifurcation, causing dislocation of the portahepatis and compression of the main right and left hepatic ducts with peripheral bile duct dilatation
Gonzalez et al[1], 2009 Left lobeCT showed a large water density mass with internal septa and without calcifications
Sang et al[10], 2011CT and MRI revealed fluid-containing, well-defined, lobulated, multilocular, thick walled cystic masses with enhanced internal septation and convex papillae
Williamson et al[7], 2013Left lobe (2), central lobe (1)CT confirmed a large hepatic cyst with calcification. MRI showed a cystic lesion containing proteinaceous fluid or blood, which had a solid component with papillary projections
Yang et al[4], 2013Left lobeCT revealed a hypoattenuating shadow with internal septae and enhanced after intravenous administration of contrast medium
Li et al[2], 2018Left lobeCT revealed a hypoattenuating shadow with slight enhanced internal septations. Fluid on MRI revealed a low signal intensity on T1WI and high signal intensity on T2WI without enhancement
This caseCT revealed multiple sizes of hypoattenuating shadows with nodular calcification and internal septations and slight enhancement. MRI showed that internal septation separated the fluid-filled spaces and was enhanced
