Abstract
Echinococcal cysts are mostly found in the liver followed by the lungs, spleen, ovaries, kidneys, brain, bones and heart, but rarely elsewhere in the body. Disease can take place either directly from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Skeletal disease is rare and is usually due to secondary extension after haematogenous spread of the infection.
We present a case of hydatid cyst involving superior and inferior pubic ramus and retrorectal space in a 22 years old male patient, which is not a common site for the occurrence of this disease. Total cystectomy was performed for retrorectal cyst, curettage and bone cementing was done for the bony involvement.
He was well after 1 year follow up. Diagnosis is usually difficult and MRI is a good tool for reaching diagnoses. Curettage and bone cementing can be a treatment option for decreasing bony recurrences.
