The hydatid cyst stages are a cyst with a visible cyst wall (stage 1), multiseptated, multivesicular cysts (stage 2), a cyst with a detached floating endocyst membrane (stage 3a), a unilocular cyst with solid or mucinous matrix and internal daughter cysts (stage 3b), a heterogeneous solid cyst with a degenerative internal canalicular structure (stage 4), and a degenerated cyst with heavily calcified wall (stage 5) [17].
Incision on the pelvic peritoneum and the cyst wall revealed a white endocyst.
Within the pericyst lies the external layer of the cyst itself (ectocyst) and the inner germinative membrane or the endocyst.
Subsequent to this, the classical imaging appearance of daughter cysts within the mother cyst caused by endocyst invagination may develop, giving rise to a wheel-spoke or rosette appearance.
A follow-up CXR was performed after a few months of medical treatment, which showed the endocyst membranes in the process of detaching from the pericyst (Fig.
The cyst may also rupture into the bile ducts and release daughter cysts, resulting in biliary colic and jaundice; Infection is another complication, which occurs when both the pericyst and the endocyst perforate, allowing bacteria to pass easily into the cyst.
