Hydatid Cystic Disease of Lumbar Paraspinal Muscles

The larva of the tap worm Echinococcus Granulosus causes Hydatid Cystic disease in humans which is a common public health problem in many countries of the Middle east, Mediterranean, Australia and New Zealand [1,2]. The cyst of the tapworm can be found anywhere in the body but liver (55 to 70%) and lungs (20 to 30%) are more commonly affected by the tape worm.1 The viscera of the body like heart, kidneys, spleen and brain and are very rarely affected by the disease and even rarer are the skeletal muscles which are affected in only 1 to 4% of the cases [3]. We present a case report of hydatid disease which involved the paraspinal muscles of the lumbar back without any involvement of liver or lungs.
