Intraventricular hydatid cyst in a child

Abstract

Hydatid disease is caused by the infestation of the larvae of tapeworms of the genus Echinococcus. The definitive hosts of Echinococcus are various carnivores, the common being the dog. All mammals (more often sheep and cattle) are intermediate hosts. Humans get infected through the feco-oral route by ingestion of food or milk contaminated by dog feces containing ova of the parasite or by direct contact with dogs. The most common sites of infestation are the liver (75%) and lungs (15%). Various authors state a frequency of hydatidosis of the brain ranging between only 0.2-4% of cases. [1],[2],[3] The prognosis following surgical intervention is good, especially in pediatric age. [2],[3] Hence early diagnosis of this condition is crucial. We report a rare case of a child with a large intraventricular hydatid cyst that had an excellent recovery following surgery.

Intracranial hydatid cyst is a rare cause of midbrain herniation: A case report and literature review

“…[6] Hydatid cysts typically involve the middle cerebral artery territory, with other less common sites being the skull, cavernous sinus, eyeball, pons, cerebellum, ventricles, and interpeduncular cistern. [15] Cerebral hydatid cysts usually grow slowly and present clinical symptoms when they increase in size and produce a mass effect. This may be due to the elastic structure of the cranial bones,[1617] open sutures, and compressibility of the neural tissue.…”

“…[131519] A study using cranial CT showed fluid that was generally the same as the CSF without perilesional edema[1]; however, Yis et al . reported perilesional edema,[17] which was also observed by Karak et al ., around the cyst in the presence of active inflammation.…”

“…Otherwise anaphylactic shock, chemical meningitis, or recurrence may occur due to the rupture of the hydatid cyst. [17151921] In literature review, we found two cases that received an urgent operation for a cerebral hydatid cyst. While Onal et al .…”

Intact protoscolices and hooklets in cytospin preparation of intra‐operative cyst fluid allow rapid confirmation of rare cerebral intraventricular hydatid infestation

“…The liver and lungs are the common sites of infestation. Cerebral or intraventricular hydatid cysts are rare manifestations, usually encountered in children and young adults 1–4 . They have been reported in patients with patency of the ductus arteriosus 1…”

“…The incidence of intracranial hydatid disease in India is approximately 0.2% 3 . Diagnosis depends upon the presentation, clinical history with corroborative imaging, serology and operative findings.…”
