PRIMARY HYDATIDOSIS IN THIGH, AN UNUSUAL LOCATION.

Abstract

Hydatidosis is a zoonotic infestation,
which generally involves the liver and the
lungs. Primary muscle hydatidosis is an
uncommon finding, accounting for only
less than 5 percent of hydatid cyst locations.
Clinical symptoms are insidious
and non-specific causing a frequent delay
in diagnosis. Intramuscular hydatid
disease can cause a variety of diagnostic
problems, especially in the absence of
typical radiologic findings.We report the
observation of a 58 year old woman consulting
for two swellings in back of left
thigh. CT and MRI thigh showing two
cystic lesions, to consider hydatid cyst or
Cysticercosis. En block surgical excision
of the cysts was undertaken. Histopathologic
findings confirmed the diagnosis
of hydatid cyst. Skeletal muscle hydatidosis
should be considered in the differential
diagnosis of limb masses. A meticulous
history taking and MRI imaging
are essential, while pericystectomy is an
effective method of treatment.
