The appearance of epileptic seizures in the early postoperative period (first 10 days) after neurosurgery is an uncommon complication. A retrospective study of 600 patients operated on for glioma, meningioma, metastatic tumor, hydatid cyst, cerebral hemorrhage and head injury (100 cases each) is the subject of this report. In 6% of the total group, seizures were found during the first 10 days following surgery. They usually appeared during the first 48 hours. In most cases (78%), fits were of the partial motor type, originating in the frontoparietal (central) region. The clinical course was benign in most cases. Good control of seizures was usually obtained by common anticonvulsants and except for a few cases, the prognosis was not worsened by the appearance of these early fits. The pathophysiology of early seizures, which are not related to cerebral scarring, is discussed. It is concluded that they are related to biochemical alterations produced by surgery, similar to what happens in early post traumatic epilepsy or in cases of seizures appearing in the early stages of cerebrovascular accidents.

A 29-year-old man, a vegetarian, agriculturist and resident of a village near Pondicherry, presented with focal seizures with secondary generalization. EEG showed a right frontoparietal focus, the blood eosinophil count was 25%, the indirect haemagglutination titre was more than 1:2048 for Echinococcus protein and Casoni's skin test was strongly positive, the CT scan showed an isolated rounded lesion in the right frontoparietal area partially enhanced with contrast media. He was subjected to surgery with complete removal of the cyst which confirmed the diagnosis of echinococcal disease of the brain. Post operatively he took only anticonvulsant drugs and was free of seizures during the two-year post-operative follow-up period. The CT scan is a superior neurodiagnostic tool to blood serological tests in the diagnosis of brain echinococcal disease.

The authors present 27 cases of cerebral hydatid cyst (CHCy) treated between 1980 and 1992. These cases of CHCy represent 2.8% of all cases of expansive nontraumatic lesions in children. Most of the patients were between 6 and 10 years of age. There was a substantial prevalence of male patients-18 cases (66.6%). Most of the children with CHCy were from rural areas. The cysts were all located in the cerebral hemispheres (none in the posterior fossa). Usually two or three lobes were affected and the cysts were most often retrorolandic. Only 8 patients (29.6%) also had pulmonary or hepatic infestation. All patients were operated on immediately the diagnosis was established. Operative mortality was very low (1 patient died immediately after surgery). There have been 11 cases of recurrence; all these patients have been reoperated on. Neurological sequelae were mainly partial and general seizures. Epilepsy developed postoperatively in five patients. Paresis, which usually disappears in time, was the most common motor disturbance. Two other important postoperative complications were subdural effusion and ventricular dilatation (six cases). There have been five cases of multiple recurrences (four of these patients have since died). Treatment with albendazole was used in three cases without significant results.

A series of 30 documented cases of intracranial hydatid cyst out of 33 pediatric and 45 total patients admitted to the Department of Neurosurgery of the School of Medicine at Istanbul University within the years 1952-1996 is presented. The pediatric population consisted of 73% of the series. Twenty patients (66%) are alive and well after a follow-up period of 8-45 years (mean 21.5 years). Six patients (20%) died and 4 (13%) were lost to follow-up. There were 3 early postoperative deaths (10%), 2 being in the pre-CT era. In 4 cases (13%), brain involvement was secondary, and 2 cases (7%) had multiple intracranial hydatid cysts. Age ranged from 4 to 16 years, with a mean of 10.4. There were 5 intraventricular (17%) and 2 (7%) intracranial extradural settlements. No children with posterior fossa hydatid cyst, primary skull hydatidosis or concomitant spinal involvement were detected. One patient (3%) presented with "rhinorrhea" which in fact was a hydatid fluid leak. Preoperative pseudocerebellar syndrome, convulsion and extrapyramidal signs were seen in 6 patients each (20%). Five patients (17%) had permanent visual deficits, 3 being in pre-CT era. Out of 29 patients operated on, hydatid birth with intact cyst removal was achieved in 18 cases (62%), with no other manipulation needed. This rate has increased to 70% in the CT era. Intraoperative accidental rupture occurred in 8 cases (28%), of which 7 were localized frontally or had a frontal involvement (88% of the ruptured cases). Of the patients with intraoperative rupture, 5 are dead (63%) and they were all primary. In contrast, all 3 cases alive with intraoperative rupture are secondary. Three cases were punctured on purpose (10%). Four of the operated patients (14%) required long-term antiepileptic therapy, 3 having no preoperative seizures. Only 1 patient required a shunt (3%). Four cases had recurrence, all with intraoperative cyst rupture (14%). The long-term evaluation of the results yielded an overall mortality rate of 21%. Routine use of CT after the 80s decreased the rate to 14%. With the analysis of 50 years of data, it is strongly concluded that brain involvement in pediatric hydatid disease is a primary process if delayed diagnosis and insufficient treatment of extraneural hydatidosis are prevented.

Hydatid cyst of the brain is more common in children than adults. The cyst is always solitary unless the primary site is the brain. Cerebral hydatid cyst (CHCy) is most frequently supratentorial involving the territory of the middle cerebral artery, especially the parietal lobe. This study included 16 patients who were treated for CHCy. They were 11 male patients (68.75%), and 5 female patients (31.25%), ranging in age from 6 to 40 years with an average age of 14.7 years. Most of the patients were children-12 patients (75%), between 6 to 16 years of age. All patients were from rural areas. Headache, vomiting and seizures were the predominant symptoms. Papilloedema was present in 12 patients (75%). CT and MRI were performed in all patients. The cysts were all located in the cerebral hemispheres, except one in the posterior fossa, (Rt. cerebellar hemisphere). One lobe alone was affected in 7 patients (43.8%), two lobes in 6 patients (37.5%) and 3 lobes in two patients (12.5%). Round, or oval well defined cystic lesions isointense to the CSF in T1 and T2WI, with hypointense walls in T2WI and no surrounding perifocal edema or evidence of contrast enhancement were seen in 12 patients (75%) and were classified as simple or non-complicated CHCy. Cystic lesions with surrounding, T2 hyperintense area of perifocal edema, complete and incomplete (segment) rim of contrast enhancement were seen in 4 patients (25%), and were labeled as complicated or infected cysts (cysts with superadded pyogenic infection). All patients were treated surgically, hydatid birth (delivery of unruptured cyst) was achieved in 10 patients, cyst rupture occurred in 6 patients (37.5%), with subsequent recurrence (3 patients with recurrent multiple cysts and 3 patients with recurrent solitary cysts). All the recurrent cysts were surrounded by perifocal edema and showed ring enhancement. MRI has proved to be an excellent means of studying CHCy. It will be more widely used for diagnosis and surgical planning. It provided information about the exact cyst localization, cyst contents and presence or absence of superadded cyst infection.

The authors describe the first indigenous case of hepatic hydatid disease in Thailand. A 58-year-old female presented with progressive right upper quadrant abdominal discomfort over a 6-month period. Ultrasonography and computed tomography showed a solitary cystic lesion 11 x 12 x 13 centimeter in size at the left lobe of the liver. She had never been abroad and had no livestock exposure. The first operation was complicated by spillage of the parasite which required a combination of albendazole and praziquantel and a second operation for intracystic instillation of hypertonic saline solution. Unfortunately, uncontrolled generalized seizures developed due to severe hypernatremia. She never regained consciousness and expired 3 weeks after admission. In addition, the authors also reviewed previous reports of hydatid disease in Thailand. To date, only 9 cases have been reported since 1932.

Hydatid cysts are rarely located in the brain (1 to 3% of all cases), and these are even more rarely in calcified form. We report one case of a 20-year-old woman. She had undergone surgery for a pulmonary hydatid cyst at the age of four years. She had been subject to general epileptic seizures refractory to standard anticonvulsive drugs for the past four years. Cerebral computed tomography showed calcification in the left occipital region. A calcified hydatid cyst was discovered and removed during surgery. Subsequent course has been good and the epileptic seizures have disappeared. A calcified hydatid cyst in the brain is very rare and presents diagnostic and therapeutic problems.

We are presenting magnetic resonance spectroscopy (MRS) findings of a known case of hydatid cyst operated twice in the past. A 22-years-old male patient had presented with recurrent symptoms of generalized seizures and raised intracranial tension. MRI with MRS of the lesion was performed that showed a recurrent loculated cystic lesion in right parieto-occipital lobe. MRS through the lesion was performed using repetition time (TR) of 1500 ms and time to echo (TE) of 135 ms using 2 x 2 x 2 cm voxel, from the margin of the lesion. MRS showed mildly elevated choline (Cho), depressed creatine (Cr) and N-acetyl aspartate (NAA), a large peak of lactate, pyruvate and acetate peaks.

Cerebral hydatidosis accounts for approximately 1 to 3% of all cases of hydatid disease. Generally, cerebral hydatid cysts are single lesions located in the watershed of the middle cerebral artery. Primary intracranial extracerebral hydatid cysts are extremely rare. Only 2% of hydatid cysts are localized in the skeleton, and of these 3 to 4% are found in the skull. The authors describe the case of a 10-year-old boy who was admitted to their clinic with headache and unilateral focal epileptic seizures. Computerized tomography scanning revealed a right parietal intraosseous hydatid cyst. A case of cranial intraosseous hydatid disease is presented, and the differential diagnosis and treatment are discussed in the light of literature.
