“…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].…”

“…Besides the classical CT appearance, which shows a cystic lesion spherical in shape with a sharply defined border and absorption value similar to that of cerebrospinal fluid [33, 34, 50, 59, 63], and characteristic magnetic resonance image [58, 61, 62, 64]revealing a cyst with a low-intensity rim, by the advance of new technologies, the characteristic features of in vivo proton magnetic resonance spectroscopy in intracranial hydatid cysts are described [65]. A large resonance for pyruvate was observed, besides lactate, alanine and acetate, and Kohli et al [65]concluded that in vivo magnetic resonance spectroscopy may be used as an adjunct to imgaing in the diagnosis of intracranial hydatid cysts and may also have a role in monitoring the drug therapy, i.e.…”

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 disease is one of the common parasitic infestations in many parts of the world with involvement of any organ inside the human body. Ocular hydatid cyst is one of such locations and is a relatively rare entity. However, with the help of MRI imaging and super added benefit of MRI Spectroscopy, the diagnosis of hydatid cyst can be reached to with great confidence, which dictates the proper line of management in such patients.

Hydatid disease (HD), already known by Hippocrates, is prevalent and widespread in most sheep-raising countries in Asia, Australia, South America, Near East, and southern Europe. The disease is most commonly due to Echinococcus granulosus and may occur in any organ or tissue. The location is mostly hepatic (75 %) and pulmonary (15 %), and only 10 % occur in the rest of the body [1]. Imaging modalities such as US, CT, and MR imaging are helpful in diagnosing the disease. The reliability of each method depends on the cyst's location in the body [2-5]. The purpose of this essay is to illustrate the use of CT in depicting some unusual locations of HD besides the liver and lung.
