“…This case report describes a 65-year-old Gurung Nepalese woman with primary hydatid cyst of the infratemporal fossa. The uniqueness of this case is that our patient presented with unilateral ophthalmological signs and symptoms including proptosis due to the extension of the lesion into the orbit and the orbital bones unlike previously reported cases of hydatidosis of the infratemporal fossa where most of the patients presented with swelling of the maxillofacial region [ 6 , 14 , 16 , 17 ].…”

“…Sahin et al . reported hydatidosis of the pterygopalatine fossa extending into the infratemporal fossa [ 14 ]. Orbital and osseous hydatidoses are rare comprising < 1% and 0.5–2.5% respectively of all cases of hydatid disease [ 12 , 24 , 25 ].…”

“…Head and neck involvement of echinococcosis is a rare entity and involvement of the infratemporal region is extremely rare even in endemic areas. Very few cases of hydatid cysts located in the infratemporal fossa have been reported in the literature [ 14 – 17 ]. Here, we highlight a rare case of primary hydatid cyst of the infratemporal fossa with extension into the orbital region and involving the surrounding orbital bone.…”

Hydatidosis of infratemporal fossa with proptosis – an unusual presentation: a case report and review of the literature

BackgroundHydatid disease is one of the common zoonotic diseases caused by the larval stage of Echinococcus granulosus. It is endemic in sheep-raising and cattle-raising areas worldwide and humans are an accidental intermediate host following the ingestion of the larvae. Head and neck involvement of echinococcosis is a rare entity and involvement of the infratemporal region is extremely rare even in endemic areas. Only a few cases of hydatid cysts located in the infratemporal fossa have been reported in the literature. Moreover, extension of the hydatid cyst into the intraorbital region and infiltrating into the surrounding orbital bone is even rarer.Case presentationWe present a case of a 65-year-old Gurung Nepalese woman with painless proptosis of her left eyeball of 2 months’ duration with recent progressive diminution of vision for 15 days. Radiological findings showed a cystic mass in the left infratemporal fossa extending into the left orbit and involving the surrounding orbital bone. Surgical removal was carried out. On histopathological evaluation, it was reported as hydatid cyst infiltrating into the bone. She was prescribed albendazole and discharged after surgery. However, she was lost to follow up and returned after 15 months with recurrence and proptosis of the same eye. Repeat excision of the lesion was carried out and postoperatively she was administered tablet albendazole. She was found to be disease free after 6 months of follow up.ConclusionsClinical and radiological findings are important but may not be sufficient in the preoperative diagnosis of hydatid disease especially if rare sites are involved. Proptosis may be seen in several conditions and orbital or infratemporal hydatidosis, although rare, should be considered a differential diagnosis.

“…Pterygopalatine fossa masses are rare and have a broad differential diagnosis including epidermoid cyst, meningocele, mucosal carcinoma, schwannoma, chordoma, teratoma, and neurofibroma. 7 The majority of these masses are benign in nature, although they can be locally invasive. The workup of pterygopalatine fossa lesions generally consists of nasal endoscopy, CT scan, and contrast-enhanced MRI.…”

Perivascular epithelioid cell tumors (PEComas) are a rare group of mesenchymal tumors associated with tuberous sclerosis. These tumors are typically treated with resection and rarely recur or exhibit malignant behavior. A 78‐year‐old woman presented with an incidentally discovered pterygopalatine fossa/retroantral mass. Excisional biopsy was performed and revealed pathology consistent with PEComa. Upon review of the literature, there have been 43 reported cases of PEComa of the head and neck. There is only one previously reported case of PEComa in the skull base, and none reported in the pterygopalatine fossa. Of note, the previously reported case of skull base PEComa involved an aggressive tumor with widespread metastasis. Here, we report the first case of a PEComa of the pterygopalatine fossa/retroantral region, which was treated conservatively. This rare pathology should be considered in the differential diagnosis for atypical skull base tumors.

“…However, the situation especially in early stage may force physicians. Hydatid cyst should be considered in the differential diagnosis of the following pathologies: Simple cysts, non-organize hematoma, necrotic tumor, cystic metastatic carcinoma, hemangioma, pyogenic abscesses, Amoeba abscess, Tuberculosis, fungal infections [40,41].…”

Uncomplicated Hydatid Cysts of the Liver: Clinical Presentation, Diagnosis and Treatment

Hydatid cyst of the liver is zoonosis caused by the larval stages of taeniid cestodes belonging to the genus Echinococcus and is still endemic in the South European regions, Asia, South America, North Africa, Australia, New Zealand and several Asian and European countries. The diagnosis of non complicated hydatid cyst of the liver depends on clinical suspicion. They appear in two ways as general (systemic) symptoms, and local symptoms based on the site and organ on which larva settles. While cysts sometimes recover spontaneously, more severe clinical presentations are observed in immunosuppressive individuals. Ultrasonography is the gold standard diagnostic tool and E. Granulosus antigen 5 (Ag5) and antigen B (Ag B) obtained from cyst fluid are used as a serologic diagnostic method in combination with the imaging method. The current treatment of hydatid cyst of the liver varies from surgical intervention to minimally invasive treatments (percutaneous drainage) or medical therapies. Surgery is still the best treatment tool. Percutaneous drainage and treatment of the cyst is a good option to surgery in selected cases. Multiple, superficial single cysts are the most suitable ones for surgical treatment. Also for complicated infected cysts pressing biliary tree and vital organs, surgery should be the first choice of treatment coming to mind. We believe that the laparoscopic approach should be safe to uncomplicated cysts. The purpose of our article is to provide a current review of clinical, diagnostic, and therapeutic features of hydrated cyst diseases.
