Fig. 1A —Intraperitoneal hydatid disease (HD) in 20-year-old woman with
history of liver HD. Axial sonogram of abdomen through level of gallbladder
shows cyst (arrow) compressing gallbladder (star). Cyst has
split wall in its posterior (arrowhead). This appearance is caused by
separation of laminated membrane from pericyst and is characteristic for
hydatid cysts.

Fig. 1B —Intraperitoneal hydatid disease (HD) in 20-year-old woman with
history of liver HD. Axial T1-weighted MR image shows cyst near gallbladder
and double rim is seen on posterior surface, with hyperintense pericyst
located more externally (black arrow) and hypointense middle membrane
situated internally (white arrow).

Fig. 3B —Disseminated intraperitoneal hydatid disease in 17-year-old girl who
presented with constipation and bilateral flank pain. Sagittal reformatted CT
image reveals unilocular, thick-walled retrovesical cyst (arrowhead)
displacing distal ureter causing hydronephrosis.

Fig. 4A —Intraperitoneal hydatid disease (HD) in 20-year-old man complaining
of epigastralgia. Axial sonogram of epigastrium shows large cystic lesion
(arrow) containing multiple peripheral rounded smaller cysts and
solid part (arrowhead), which settles in dependent part of cyst
pointing matrix or detached membrane, consistent with hydatid cyst
("wheel spoke" pattern).

Fig. 4B —Intraperitoneal hydatid disease (HD) in 20-year-old man complaining
of epigastralgia. Axial T2-weighted MR image shows large epigastric hydatid
cyst (arrow) containing multiple daughter cysts displacing stomach
and liver HD (arrowhead). There is also heterogeneous hypointense
lesion in splenogastric space (star).

Fig. 4C —Intraperitoneal hydatid disease (HD) in 20-year-old man complaining
of epigastralgia. Coronal contrast-enhanced CT image reveals rupture of
splenic hydatid cyst (arrow) into splenogastric space
(star). HD of liver (arrowhead) is also seen.

Fig. 5 —Disseminated abdominal hydatid disease in 17-year-old girl with
abdominal pain. Axial contrast-enhanced CT image shows intraperitoneal
uniloculated and multiloculated cysts (black arrowheads) and multiple
liver (white arrowheads) and spleen (thick white arrows)
cysts. Pancreas (thin white arrows) has thickened and heterogeneous
appearance as consequence of hydatid involvement.

Fig. 7 —Retroperitoneal hydatid disease in 25-year-old woman with right
flank pain. Axial contrast-enhanced CT image shows cystic mass
(arrow) extending to right lumbar region with barely seen central
hydatid matrix (star) in right posterior pararenal region. Large
hydatid cyst is also seen in liver (arrowhead).

hydatid disease (HD). Contrast-enhanced axial CT shows hypoattenuating lesion
(black arrow) in spleen with speck of calcification (black
arrowhead) on lateral wall and epigastric (white arrow) and
liver HD (white arrowhead).

with flank pain. Axial unenhanced CT image through upper pole of right kidney
shows large cyst (arrow) with daughter cyst (arrowhead) in
