✓ From among 1500 patients who underwent computerized tomography (CT) during an 18-month period, five cases of hydatid disease of the brain were diagnosed. The preoperative diagnosis is of paramount importance as the cyst has to be removed unruptured. The CT features of this condition are practically pathognomonic. The authors discuss the CT findings in these cases and differential diagnosis with other cystic lesions of the brain. The help that this safe and sure method of investigation gives to attain preoperative diagnosis is emphasized.

✓ Seventeen cases of aneurysmal bone cyst of the spine are reported. Clinical manifestations, methods of investigation, differential diagnosis, treatment, and pathogenesis are discussed. The condition is essentially a benign lesion, affects a young age group, and grows rapidly, often producing a paravertebral mass. Occasionally it becomes acutely exacerbated, causing irreversible damage to the spinal cord. For these reasons, prompt diagnosis and timely treatment are important. Excision of the lesion is the treatment of choice but, if not feasible, thorough curettage and radiotherapy not exceeding 2000 rads are indicated. With a two-stage operation, excision of the lesion is often possible, and the stability of the vertebral column is assured with bone-graft fusions.
