Echinococcus Disease of the Bone.
—Coley24 reported 2 cases of echinococcus disease of the bone. Both involved the bones of the pelvic girdle. In both cases the diagnosis was arrived at late in the disease and after the patients had been treated with high voltage roentgen therapy without benefit. In each case the diagnosis was made by biopsy. One patient is still alive, but the other died of complications following biopsy. Two forms of treatment are discussed. One consists in evacuation of the large cystic cavity and treatment with phenol or formaldehyde in the hope of producing fibrosis and subsequent obliteration of the cavity. The other, more ideal one consists in wide excision or amputation of the bone involved. The author stated that only 3 cases of osseus hydatid disease had been reported in this country up to 1930.
