Primary hydatid cyst of the posterior cervical triangle

Abstract

Hydatid cysts in the cervical region are extremely rare. We report herein a case with a hydatid cyst that was primarily located in the posterior cervical triangle without any pulmonary or hepatic involvement. A hydatid cyst of the neck should be considered in the differential diagnosis of lesions in the cervical region, in endemic areas, so as to avoid any dangerous complications such as contamination and a fatal anaphylactic reaction.

Primary Large Hydatid Cyst of The Neck

“…Only a few case reports are found in the literature [1,2]. Most hydatid cysts in the head and neck are asymptomatic, and symptoms depend on the location and size of a cyst.…”

“…Lesions are characteristically slow growing. A past medical history, family history, patient's occupation, and patient's residence may suggest a diagnosis of a hydatid cyst in differential diagnosis, but unless suspected or demonstrative radiologic findings are available, preoperative diagnosis may be missed [2]. When hydatid disease is found, patients must undergo careful complete systemic examination, especially to define hepatic and pulmonary lesions and other sites of involvement [3,4].…”

“…In previously reported cases of hydatid cyst of the neck, cystotomy and subsequent excision of the pericystic tissue was performed. In parenchymal diseases such as a cyst of the lung, pericystic tissue can be left behind as a parenchyma-sparing procedure [1,2]. Combination of medical therapy with imidazole derivatives has been used in the management of patients with recurrence and high-risk contamination.…”

“…The primary host is the dog. Occasionally hosts are man [1,2]. Hydatid disease has its highest incidence in sheep-and cattle-rearing regions, such as the Mediterranean countries, the Middle East, South America, New Zealand, Australia, and Southeast Asia [3].…”

“…In the intermediate host, the embryos enter the portal circulation in the intestines and most of them are caught in the liver, whereas some reach the pulmonary arteries. Those entrapped within the lung parenchyma develop cysts in the lungs, whereas some may even pass through the lungs and reach the systemic circulation [1,2]. The most frequently involved organ is the liver (65%) because most of the embryos are trapped within it [5].…”
