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.

A parasitic tapeworm, called Taneia Echinococcus, causes hydatid disease. Hydatid disease is endemic in sheep and cattle-raising areas of the world. Hydatid disease of the central nervous system constitutes 2%-3% of all reported cases of hydatid cysts. In our institution, 23 children underwent surgery for intracranial hydatid cysts between 1979 and 1995. There were 14 boys and 9 girls, aged between 3 to 16 years (mean 8.8 years). Signs and symptoms were related to the site and size of the cyst. Headache and vomiting due to increased intracranial pressure were the most common presenting symptoms. A round cystic lesion without perifocal edema and rim enhancement is the characteristic appearance on a computed tomography (CT) scan. A magnetic resonance image visualizes cyst location better than CT. Associated systemic hydatidosis in four of our patients involved kidney, liver, lung, and liver and lung, respectively. Intact cyst removal was achieved in 14 patients. In three patients with infected or inflamed hydatid disease, the ruptured cyst capsule was totally resected. Aspiration and extirpation were performed in only one patient. Eleven patients were treated with chemotherapeutic agents such as albendazole or mebendazole due to cyst rupture during surgery or associated systemic hydatid disease. Hydatid disease can also be seen in Western countries because of travel and migration. Cerebral hydatid cyst should be kept in mind for the differential diagnosis of cystic lesions.

Cystadenomas of the pancreas are rare tumors. They represent about 10% of the pancreatic cystic masses. Several hundred cases seem to have been reported so far. These tumors appear as serous and mucinous. Over 13 years period (1983-1996) we treated 22 patients for cystadenoma of the pancreas. All patients were women. There were 6 serous and 16 mucinous cystadenomas. The average age in the serous group was 31 years (ranging from 23 to 42 years) and 43 years (ranging 17-64) in mucinous group. Two patients had tumor in the head, 20 others in the tail and body of the pancreas. The diameter of these tumors varied from 3.5 to 17.0 cm (average 9.6 cm). The leading symptoms were epigastric or left subcostal pain in 19 patients, palpable mass in 10, weight loss in 5, vomiting in 5, and melena in one patient. Tumor was accidentally found in a women undergoing abdominal operation for enteric fistula after hysterectomy. Serum amylase was moderately elevated in two patients. Diagnosis of pancreatic cystadenoma was proposed preoperatively in 16 patients (72.7%). In other cases, diagnoses of pancreatic cysts in 5 patients or hydatid cyst in 1 patient were made. An ideal operative removal (excision) was done in 7 patients, both excision of the tumor and splenectomy in 2, while distal pancreatectomy and splenectomy were carried out in 13 others. There was no mortality. One female patient developed left subphrenic abscess and left pleural effusion which were successfully treated by drainage and thoracocenthesis. One patient developed transient pancreatic fistula. All patients have been under close follow-up from 6 months to 13 years and all stayed symptom free so far.

A 49 years old woman was admitted to the hospital for abdominal pain with vomiting. At the examination, there was a deep and hard epigastric mass. The diagnosis of pancreatic cyst was established by ultrasonography and CT Scan. The hydatid cyst was recognized before surgery on the basis of the epidemiological data and the existence of calcified shell. The treatment consisted in the resection of the protruding dome with epiplooplasty. The postoperative evolution was simple. From this observation and reported data, complications and treatment of this uncommon localization were discussed.

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.

We report herein an unusual case of primary mesosigmoidal hydatid cyst that presented as acute left colonic obstruction mimicking sigmoid colon cancer. A 61-year-old man with a 3-day history of abdominal pain, distention, obstipation, vomiting, and fever was admitted to the emergency department of our hospital. Surgery was performed under a presumptive diagnosis of acute left colonic obstruction. The intraoperative findings were highly suggestive of sigmoid colonic carcinoma and Hartmann's procedure was performed. Histopathological examination of the pathological specimen revealed an isolated hydatid cyst embedded in mesosigmoid which had caused mechanical sigmoidal obstruction. Primary extrahepatic, intra-abdominal localization of a hydatid cyst is not unusual. Therefore, as a hydatid cyst may cause a wide variety of clinical syndromes, it should be kept in mind in the differential diagnosis of mechanical bowel obstruction, especially in endemic regions.

The hydatid cyst of the adrenal gland is still an exceptional localization. Only eleven cases have been described in the literature. A new case of isolate suprarenal hydatidosis is reported in one 28 years old patient, that the signs consisted in pains of the right flank and vomiting. The diagnosis has been based on the imagery, particularly the computed tomography associated to the hydatid serology, confirmed during the operation and by the pathologic examination of the resected piece. The treatment consisted in a simple cystectomy with conservancy of the gland, the operative sequelae have been simple. The interest of this cases lies in the rare feature of this hydatid localization that the diagnosis is difficult. Among the various suggested surgical methods, the simple resection of the cyst is still the best treatment that permits to keep the gland.

Echinococcosis is a human parasitary disease. In 2002, 29 new cases of liver echinococcosis were recorded in Croatia. Liver is the most common site of hydatid cysts. Nine patients with echinoccocal liver disease were operated in our department in 2002. Here we present a case where a patient with verified hydatid cyst in the left liver lobe developed high fever, jaundice, nausea, vomiting and pain in the upper abdomen. The symptoms were initially ascribed to the acute cholangitis. After unsuccessful antibiotic treatment, computerized tomography and endoscopic retrograde cholangiopancreatography (ERCP) were performed, demonstrating daughter cysts in the common bile duct. During ERCP, papilotomy was made and daughter cysts were extracted. Hydatid cyst was surgically removed, and a communication between the cyst and left hepatic duct was noted during surgery. Pericystectomy, choledochotomy, removal of remaining daughter cysts from the common bile duct, and sutures of left hepatic duct were performed. The patient recovered fully after the surgery. One of the possible complications of the liver hydatid cysts is the communication between cyst and the biliary tree. Such communications are usually asymptomatic, but symptoms can also mimic acute cholangitis and jaundice, which may lead to the misdiagnosis of the patient's condition.

Hydatid disease is a parasitic infestation caused by a tapeworm of the genus Echinococcus, and it is common in Mediterranean regions. Cystic lesions cause symptoms via compressing adjacent organs or may be totally silent. Morbidity is usually secondary to free rupture of the echinococcal cyst with or without anaphylaxis, infection of the cyst or dysfunction of affected organs. The cyst of Echinococcus granulosus is commonly located in the liver and frequently causes no symptoms. Anaphylactic reactions as a result of cyst perforation generally occur during interventions such as needle aspiration or open surgery; however, the spillage of cyst fluid with intravascular spread resulting from trauma may also trigger anaphylaxis, and rare case reports of this kind are present in the literature. We report the case of a 17-year-old man who was admitted to the public hospital with a sudden onset of nausea, vomiting and fainting. After a short period of intervention in the emergency department he died. As the cause of his sudden death was unknown, a forensic autopsy was carried out by the Forensic Council of Turkey. The autopsy revealed a macroscopically non-ruptured hydatid cyst in the liver and laryngeal oedema. In histopathological examination, two scolices in the pulmonary artery and inflammatory infiltration mainly composed of mast cells in the larynx were detected. Sudden death in this case was attributed to anaphylactic shock caused by intravascular spread of the cyst contents.

The cerebral localization of the hydatid disease is rare, under 2%, and it primarily affects children. We report 4 cases of children presenting with a cerebral hydatid cyst (2 boys and 2 girls, mean age 9 years). Clinical symptoms were very progressive, the disease was frequently diagnosed several months (1-12 months) after onset of symptoms most often headaches and vomiting. One patient presented with a right tonic-clonic seizure 3 days before hospitalization. The diagnostic was confirmed in all cases by Cerebral CT scan. All the patients were screened for other localizations. One patient also presented with pulmonary and hepatic hydatid cysts. Hydatid blood tests were positive in only one case. The treatment was surgical for all the patients (using hydropulsion) without complications in 2 cases. One child presented with meningitis, and the other child with signs of secondary ICHT related to residual mass which required its puncture.
