Abstract
Hydatid disease is endemic in Tunisia and has been considered as one of the most common surgical pathology. Several localizations have been described, but hydatidosis of the liver is the most frequent clinical entity. Primary hydatid cyst of the gallbladder is very rare. We report in this observation a new case of primary hydatid cyst of the gallbladder diagnosed by Magnetic Resonance Imaging (MRI).
Highlights
Human hydatid disease is a frequent in Tunisia where echinococcosis is endemic
To eliminate gallbladder neoplasm; a CT abdominal scan was performed showing inflammatory gallbladder wall which is free of suspect lesions (Figure 2). Against this diagnosis difficulty; it has been decided to practice a magnetic resonance abdominal imaging. This examination showed many daughter cysts in the lumen of the gallbladder (Figure 3-A,B); while hepatic parenchyma proved absolutely normal (Figure 3-C) Antiechinococcal antibodies were not found in serum
Many hypotheses are proposed to explain the exact pathogenesis of the primary gallbladder hydatid cysts
Summary
Human hydatid disease is a frequent in Tunisia where echinococcosis is endemic. To eliminate gallbladder neoplasm; a CT abdominal scan was performed showing inflammatory gallbladder wall which is free of suspect lesions (Figure 2). Against this diagnosis difficulty; it has been decided to practice a magnetic resonance abdominal imaging. This examination showed many daughter cysts in the lumen of the gallbladder (Figure 3-A,B); while hepatic parenchyma proved absolutely normal (Figure 3-C) Antiechinococcal antibodies were not found in serum. It has been found a cyst of the body of the gallbladder which is inflammatory and deformed. At six month follow up, the patient has had no recurrence of hydatid disease
