“…Analysis of records showed that out of 9 pediatric cases, only 4 cases had unruptured evacuation, giving a 44% rate of hydatid birth. Comparing this rate in the pre-CT era with a 70% intact removal rate (14 patients) in 20 pediatric cases operated on within the next 20 years – mostly in the CT era – reveals the invaluable place of high-technology diagnosis in neurosurgery [49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65]. Only 1 case out of 14 with CT had a misdiagnosed preoperative lesion (extradural retroclival hydatid cyst), as published in 1994 by Canbolat et al [33].…”

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.

“…Orbital hydatids are typically unilocular, hypodense, nonenhancing cysts [7,8,13,14] and these diagnostic studies demonstrate a well-circumscribed cystic mass in all patients. Fine peripheral rim enhancement following contrast administration is often well documented in CT and MRI [7,8,13,14] . At present, orbital MRI has proved to be a very useful diagnostic tool to rule out other cystic lesions with less water content in spite of its limited use due to high cost in endemic areas [2] .…”

Retrobulbar hydatid cysts are extremely rare while non-orbital forms constitute a still frequently encountered disease in underdeveloped countries. This report concerns a patient with a primary hydatid cyst in the orbit. A 22-year-old female patient was admitted to our hospital with proptosis of her right eye, conjunctival edema, hyperemia and headache. The family and patient's own past history were significant for continuous contact with sheep. The neurological examination revealed a retrobulbar mass and limited ocular motility in lateral direction on the right side. The papilledema was found in ophthalmoscopic examination and loss of vision was fixed. The eyeball was non-reductible and non-pulsatile. A frontoparietal craniotomy and orbitotomy was performed and then the mass was removed totally. This case was accepted as a primary infection because of no findings and previous history of liver or lung cysts. In the treatment of orbital hydatid cysts; early diagnosis, surgical excision and then systemic use of albendazole are suggested. Although cyst rupture is rather common, it sometimes results in severe anaphylactic reaction anaphylaxis, incomplete removal or secondary implantation. To avoid of a cyst rupture, intraoperative aspiration is recommended.

“…Immunodiagnostic tests for an isolated orbital hydatid cyst are almost always negative [13]. In this case, though the age of the patient was atypical, there was a typical clinical presentation and location of the cyst, an eosinophilia, a positive indirect haemagglutination test for hydatid disease and disseminated, similar, anechoic cystic masses in the liver, lung, spleen and orbit on imaging studies; based on these findings, the diagnosis of disseminated hydatid cyst was seriously considered before surgery.…”

Orbital hydatid disease is rare, even in endemic areas. We present a case of disseminated hydatid disease involving the orbit, spleen, lung and liver in a lady aged 35 years. Based on a typical clinical presentation, presence of eosinophilia, a positive indirect haemagglutination test for hydatid disease and presence of similar disseminated, anechoic cystic masses in the liver, lung, spleen and orbit on imaging studies, the diagnosis of hydatid cyst was seriously considered before surgery. Aspiration of the cyst, followed by cryo-extraction of the cyst wall through transconjunctival route was safely performed. Histopathological examination confirmed the diagnosis. In conclusion, multisystemic involvement of liver, lung and spleen in a case of orbital hydatid cyst has never been reported before. The surgical technique adopted in this case is safe and effective.
