CECT Upper abdomen:

• Well-defined, rounded hypodense cystic lesion in right lobe of liver. Multiple collapsed thin membranes are seen within it (yellow arrows).
• Loculated collection in perihepatic region and involving the right abdominal wall. It is communicating with the above cystic lesion (white arrow).

NONE! This is an Aunt Minnie.

• Urgently inform the referring clinician and refer to surgical team on call.
• Urgent surgical intervention is the mainstay of treatment  – removal of cyst membrane and closure of tract.
• Supplementary treatment with anti-helminthic drugs.

• Hydatid disease is caused by the parasitic infection of Echinococcus.
• Echinococcus is a tapeworm found in dogs (definitive host), pigs (intermediate host), sheep, goats and cattle. Humans are accidental hosts. Infection occurs by ingestion of food which is contaminated by Echinococcus eggs.
• Liver is the most involved organ followed by lungs and spleen. Cerebral and spinal hydatid cysts have also been reported.
• Cyst wall is made up of 3 layers, namely:
  • pericyst
  • exocyst
  • endocyst.
• Calcified hydatid cysts can be seen as rounded opacities on radiographs.
• PAIR procedure (Puncture, Aspiration, Injection and Re-aspiration) is usually performed for treatment of un-ruptured hydatid cyst.
