RESUMO
Hydatid cyst disease is a rare parasitic infestation caused by larvae of Echinococcus granulosus. Although larval stage of this parasite can thrive in any part of the body, especially lungs and liver; head and neck involvement is rare. Pterygopalatine fossa involvement is reported in two cases in the literature. In this report we represent a case with solitary, secondary pterygopalatine fossa hydatid cyst extending in to the maxillary sinus, orbita, sphenoid sinus and skull base.

OBJECTIVE: We report a very rare case of a hydatid cyst in the infratemporal fossa, causing visual loss over a 10-day period, which disappeared with rapid surgical and medical treatment. CASE REPORT: A 14-year-old girl presented with right exophthalmos and visual loss. Over a 10-day period, her visual acuity had decreased to detection of hand motion only, due to pressure on the optic nerve caused by a parapharyngeal cyst pressing through a inferior orbital fissure on the right side. A craniotomy had previously been performed for a right frontoparietal hydatid cyst. The patient had been treated intermittently with albendazole. The patient was primarily diagnosed with hydatid cyst, on the basis of her previous medical history and radiological findings, and underwent surgery. Three cysts were carefully removed from the right maxillary sinus, via a standard Caldwell-Luc approach, and the surgical area was irrigated with hypertonic saline. CONCLUSION: Infratemporal hydatidosis is very rarely reported in the world literature, although hydatid cysts are endemic in many countries, including Iran. We discuss the common presenting features, investigation and treatment options for infratemporal hydatosis. Constant evaluation of adjacent organs is necessary, with treatment as required, due to the propensity of hydatidosis to recur in essential organs. Immediate surgery is recommended, both to prevent the development of disease and to improve the prognosis.

Myiasis is a term derived from the Greek word "myia", meaning invasion of vital tissue of humans or other mammals by fly larvae. The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions, alcoholism and senility. Its diagnosis is made basically by the presence of larvae. This paper reports a case of oral and maxillofacial myiasis involving 273 larvae in a patient with epidermoid carcinoma without physical or neurological deficiency. The patient's management was antisepsis, larval removal and general care, before death after three months.

The writers give an account of a cervicofacial hydatid dissemination case, provoked by iterative ponctions of hydatid cyst initially isolated in the left maxillary sinus. They state diagnostic and therapeutic difficulties sometimes found and they insist on the role that must be played by immunologic tests in diagnostic approach and treatment monitoring of this disease which is unfortunately current and serious.
