Hydatid cyst excision using Dowling's technique of hydrodissection

Neurohydatidosis is a rare zoonotic disease in nonendemic areas and a differential diagnosis of intracerebral cysts workup. Appropriate imaging modalities with serology are required for proper diagnosis. The gold standard surgical intervention is the Dowling-Orlando technique.

We provide a detailed description, with key surgical steps, for total excision of hydatid cysts with intact capsules by hydrodissection. We also describe the relevant surgical anatomy, with indications, limitations, and possible complications.

Hydrodissection allows safe resection of hydatid cysts without further damage to the surrounding parenchyma and reduces the risk of cystic wall rupture.
