RESUMEN
Hydatid cyst disease is a rare parasitic disease caused by the larval stage of Echinococcus. This parasite in the larval stage can thrive in many parts of the body, most frequently in the liver. Head and neck involvement of the disease is rare. Herein, we present a case of primary hydatid cyst occurring in the infratemporal fossa, which is an extremely rare localization.

This paper presents a patient with echinococcosis of infratemporal fossa invading intraorbital and basicranial sites. With the excellent collaboration between doctors and nurses, the patient received total resection of hydatid asci and internal capsules and anti-echinococcosis therapy. Then, the patient significantly improved and was discharged from hospital successfully.

We describe a case of human lagochilascariasis, with skull-base involvement and a chronic and relapsing course after treatment. This rare parasitic infection is usually manifested in the head and neck area, characterized by progressive granulomatous inflammation and the formation of abscesses. Transmission to humans most likely occurs by the consumption of undercooked meat of wild rodents. On the basis of literature studies, we propose the most likely life cycle of the parasite that involves wild feline and rodent species, with humans as accidental hosts. Even in endemic areas, it is very difficult to recognize the disease at an early stage. Progression will eventually lead to involvement of the (central) nervous system, as described in our case. Treatment is often difficult and involves resection and prolonged treatment with anthelmintic drugs. Recurrences are not uncommon and at present, long-term oral administration of ivermectin seems to be the most effective treatment.

Hydatid disease is caused by the parasitic tapeworm Echinococcus. This parasite in larval stage can thrive in many parts of the body, most commonly in the liver and the lung. Hydatid disease in the head and neck is uncommon and hydatid cyst presents rarely as a cervical mass. Cervical vertebral echinococcosis is rare. We report a 14-year-old girl with multiple cervical spine hydatid cysts of the C1-C2 vertebrae that spread into the surrounding paravertebral tissues and involve the nasopharynx and the skull base particularly the left jugular foramen. This process has caused a progressive swelling in the left side of the neck located in the retrostyloid compartment of the parapharyngeal space with paralysis of cranial nerves (VI, IX, X, XI, XII). The diagnosis was made based on the image obtained from CT and MRI examinations. Characteristics of this rare disease, diagnosis and treatment difficulty are discussed.

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.

Hydatid disease has a high incidence in the countries of the temperate zones such as Turkey. Only few cases in the head and neck region have been reported in the literature. Our case, an unusual localization of hydatidosis, i.e. hydatid disease of the infratemporal fossa of a 9-year-old male patient suffering from a swelling of the left maxillary region which was diagnosed by CT, is presented. The lesion visualized on CT images was compressing the neighbouring structures. The possible diagnosis was made based on the images obtained from CT examination.
