Synovial sarcomas (SS) account for 7-8% of soft-tissue cancers and 3-5% of all cases with head and neck involvement. Synovial sarcoma of the infratemporal fossa is very rare In this article, we report the fourth case of SS of infratemporal fossa and the first case with intracranial extension via the foramen ovale. A 31-year-old man admitted with a one-year history of intense pain in his right j...

There are some difficulties in approaching and removing the lesion in infratemporal fossa because of its anatomical location. After wide excision of tumor lesion, it is also difficult for reconstruction of mandibular condyle and cranium base on infratemporal fossa. Besides, there are some possibilities of cerebrospinal fluid leakage, intracranial infection and bone resorption. It is also challe...

Chondrosarcoma (CS) is an uncommon malignant mesenchymal tumour showing cartilaginous differentiation which rarely presents in the jaws. CS represents 10-20% of all malignant bone tumours and less than 5% of tumours in head and neck region. Among the infrequent subtypes of CS, dedifferentiated CS is a sinister variant that presents with singular features and has extremely poor prognosis. We rep...

The infratemporal fossa (ITF) is a potential space bounded by bony structures that can be occupied by both benign and malignant tumors. It is also a potential area of abscess development, most commonly of dental origin. As with any abscess, the treatment of an ITF abscess is surgical drainage. We present a case of an ITF abscess involving the pterygoid muscles following dental extraction in a p...

Idiopatic pseudotumor (IP) is a non-specific, non-neoplastic, inflammatory process without identifiable local or systemic causes. IP most commonly affects the orbit, comprising 5% to 8% of all orbital masses with occasional extension to other areas of the skull base. The ophthalmology literature has detailed reviews of IP as a space-occupying intraorbital lesion, but lesion involving only the s...

Hydatid disease is a considerable health problem worldwide, but hydatid cysts in the infratemporal region are extremely rare, even where the parasite is endemic. Here we report on a 17-year-old female who presented with a benign swelling in the infratemporal fossa. During surgery a cystic mass was discovered and histopathologic examination confirmed the diagnosis of a hydatid cyst. Although rar...
