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.
Cyst is composed of endocyst, ectocyst and pericyst.
The hydatid cyst was laid open after instillation of the cetrimide solution, fluid aspirated, and the endocyst were removed (Figure 3).
MICROSCOPIC EXAMINATION: Sections from the both cysts showed outer laminated hyaline membrane the ecto cyst and inner granular germinal layer the endocyst, focally attached to the endocyst are brood capsules containing scolices within.
** endocyst: inner germinal layer gives rise to brood capsules (daughter vesicles), scolices
Smaller daughter cysts arise from the germinal epithelium which is the endocyst Cyst size may vary from 1 to 20 cm, in endemic areas all liver cysts are considered to be hydatid unless proven otherwise.
Liver hydatidosis is characterized by progressive growth of the hydatid cyst, which in its mature form is a fluid filled cavity, delineated by an external host derived layer called PERICYST and two internal parasite derived layers called ENDOCYST. The hydatid cyst grows slowly and remains asymptomatic for many years.
liver showed red coloring brownish and friable consistency with the presence of several endocysts. Macroscopically, these cysts were whitish and were situated in the hepatic parenchyma near the organ surface, producing infection both in the central and peripheral regions, and in some samples, there was perforation of organ stroma, allowing externally viewing of the cyst.
Computed tomography (CT) scan of the abdomen showed atypical lesions, suggesting a tumor, but magnetic resonance imaging revealed well-defined cysts with internal structure suggestive of CE, with detached endocysts (Figure 1, panels A, B).
