The Dowling-Orlando technique in a giant primary cerebral hydatid cyst: a case report.

Hydatid cyst disease is a parasitic illness that is rarely located in the brain. We present a case of a 26-year-old female who complained of headache, nausea, and vomiting. The diagnosis was intracranial hydatid cyst disease and was confirmed with radiological and serological tests. Neurological examination revealed papilloedema and left-sided pyramidal signs. She was operated on using the Dowling-Orlando technique. The cyst was removed without rupture, and therapy was completed with albendazole for a period of four weeks. In this article, we discuss the application of the Dowling-Orlando technique, microsurgery, the Valsalva manoeuvre and the positioning of the patient such that gravity could facilitate surgical removal of a giant cerebral hydatid cyst.
