Vertebral hydatid cysts are rare and found in less than 1% of all the cases of hydatidosis. Neural compression is common in vertebral hydatidosis. The prognosis is generally regarded as very poor. This paper examines the natural history and complications which may arise during the treatment of vertebral hydatid cyst, and discusses their treatment. Thirteen cases of hydatid disease a ecting the vertebrae are presented. The patients were admitted with symptoms of spinal cord compression. Twelve were treated by laminectomy and one by costotransversectomy. Low back pain radiating to the legs and lower extremity weakness were the predominant symptoms. Di erent degrees of pareses were present in 12 patients. Nine patients had impaired sensation in lower extremities. In 13 patients, 27 operations were performed. The major complication of surgery was the death of one patient due to the formaline irrigation. The surgical goal should be an extensive removal of the cysts and a ected bone. The surgical area needs to be irrigated with hypertonic saline. Mebendazole or albendazole therapy seems to retard the recurrences and control the disease.
The incidence of growing skull fractures ranges from less than 0.05% to 1.6%. We reviewed 22 growing skull fracture patients retrospectively. There were 15 boys and seven girls ranging in age from newborn to 6 years (mean: 12.4 months) at the time of injury. Falling was the most frequent cause of injury. In total, 17 patients presented with a scalp mass. The scalp was sunken over the bone defect in three patients. Other symptoms and signs were seizure in five patients, hemiparesis in four, recurrent meningitis in one, and pulsatile exophthalmus in one. The most common location was the parietal region. The extent of dural defect was always greater than that of bony defect, except in one case that had been previously shunted for hydrocephalus. In another patient with a growing fracture in the posterior cranial fossa, the dural edges could not be exposed, although a wide craniotomy was performed. Therefore, a cystoperitoneal shunt was inserted. Gliotic tissue was present in all the patients. Cyst or cystic lesions were observed in only nine patients, duraplasty was performed in 21, 16 were neurologically intact, and six had minor deficits. All patients under the age of 3 years with a diastatic skull fracture should be closely followed up. A sustaining diastatic fracture and brain herniation through the skull defect shown on CT or MRI imply a growing skull fracture.
Brain involvement in hydatid disease occurs in 1 to 2% of all Echinococcus granulosus infections. Fifty to 75% of intracranial hydatid cysts are seen in children. This study included 19 children who underwent surgery for intracranial hydatid cysts between January 1979 and September 1992. There were 12 boys and 7 girls, ages 3 to 16 years (mean, 8.1 yr). Headache and vomiting were the predominant symptoms. Papilledema was present in 16 patients, and 2 patients had secondary optic atrophy. A round, cystic lesion without perifocal edema and rim enhancement was detected on the computed tomographic scans of 13 patients. The cystic lesions with rim enhancement and perifocal edema were noted on the computed tomographic scans of 3 patients. Of these three patients, two subsequently had a recurrence. Total removal of the cyst without rupture was achieved in 12 patients. Only a 3-year-old boy in whom the cyst ruptured at surgery died. Seven patients in whom either the hydatid cyst ruptured at surgery or there was systemic hydatid disease received mebendazole therapy. Mebendazole seems to be effective in hydatid disease. Cerebral hydatid cysts should be removed in toto without rupture. The preoperative diagnosis is very important in planning surgery. When a cystic lesion is detected on computed tomographic scan, hydatid disease should be taken into consideration in countries where hydatid disease is endemic.
