Solitary fibrous tumors are rare tumors originating from the mesenchymal tissue. In most cases they arise from the subpleural tissue but have also been described in other locations in the body. Most such tumors in the head and neck region occur in the orbit. Although malignant tumors can occur, benign tumors are far more common. The therapy is surgical excision. For a conclusive diagnosis, a ty...

Extraskeletal osteochondroma in parapharyngeal space is very rare. It is important to note that such a diagnosis be considered when a discrete, ossified mass is localized in soft tissues, even at atypical sites. Its diagnosis is based on radiological and histopathological examination. We should be clinically aware of this benign entity as no malignant transformation or metastasis has been repor...

SUMMARY We report the CT and MR findings in a patient with malignant peripheral nerve sheath tumor in the parapharyngeal space who had neither a family history nor stigmata of neurofibromatosis. A high-resolution CT scan of the temporal bone revealed bony erosion and widening of both the foramen ovale and the bony portion of the eustachian tube. A temporal bone MR image showed an intensely enha...

Heterotopic brain presenting as a giant, growing, single locular cyst at the parapharyngeal space has not been reported before, to our knowledge. We present such a case, with MR imaging findings, in a 13-month-old girl. A well-demarcated giant cystic mass was noted in the left parapharyngeal space from the skull base to the submandibular region. Airway compression and deformity of the left mand...

This study investigates the possible characteristic Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings of parapharyngeal Pleomorphic Adenoma (PA), which is rarely found, reported. We analysed 6 cases that had been diagnosed with nasopharyngeal PA and surgically treated in the last 6 y with both the symptoms of the patients and the characteristics of the tumours. The most fre...

A ranula is a bluish, transparent, and thin-walled swelling in the floor of the mouth. They originate from the extravasation and subsequent accumulation of saliva from the sublingual gland. Ranulas are usually limited to the sublingual space but they sometimes extend to the submandibular space and parapharyngeal space, which is defined as a plunging ranula. A 21-year-old woman presented with a ...

Kimura's disease (KD) is a rare idiopathic condition of unknown etiology. The disease is characterized by swelling and lesions in the head and neck region, with involvement of the subcutaneous soft tissue, major salivary glands and lymph nodes. Patients almost always have eosinophilia and elevated serum immunoglobulin E levels. The diagnosis is established by biopsy. KD is usually self limiting...
