[Eagle's syndrome].

OBJECTIVES: Elongated styloid process also known as Eagle's syndrome is an entity that may be the source of craniofacial and cervical pain. It is frequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of oropharyngeal and maxillofacial diseases. From four observations of Eagle's syndrome, we recall the clinical and radiological findings of this affection. MATERIAL AND METHODS: Retrospective analysis of four patients examined during a 2-year period. These patients presented cervical pain associated with headache, vertigo, otalgia and dysphagia. All patients were explored by conventional radiographs and three-dimensional computer tomography reconstruction. RESULTS: Digital palpation of the fossa reproduced and exacerbated the pain. Neck radiographic examination showed a bilateral elongation of the styloid process in both cases. The cervical scanner showed a bilateral elongation of the styloid process in all cases. CONCLUSION: Eagle's syndrome is a frequent entity that remains vaguely known by physicians. Three-dimensional computer tomography is useful for the diagnosis of this entity.

[Ectopic thyroid].

PURPOSE OF STUDY: Ectopic thyroid is defined as thyroid tissue not located anterolaterally between the second and the fourth tracheal cartilage. This anomalous localization results from abnormal embryologic development and/or migration of the gland. The purpose of this study is to demonstrate the role of imaging in the preoperative evaluation of ectopic thyroid. MATERIAL AND METHODS: A 13-year-old girl with no other significant medical history, consulted for dysphonia, fullness in the throat and breathing difficulties. Examination of the oral cavity and oropharynx showed a large mass attached to the base of the tongue, the mass was evaluated by ultrasanography, computed tomography, magnetic resonance imaging and scintigraphy. RESULTS: Ultrasound sonography showed a well-defined hypoechogenic mass in the posterior end of the tongue. Scintigraphy showed hyperfixation at the base of the tongue with no fixation in the normal thyroid site. Computed tomography scan revealed a spontaneously hyperdense spherical basilingual mass with a high enhancement after contrast injection. In MRI, the mass was isointense with the muscle in T1-weighted images and hyperintense in T2 weighted images. CONCLUSION: Ectopic thyroid must be evoked in the presence of any basilangual mass. Scintigraphy and ultrasanography are gold standard in demonstration the ectopic thyroid tissue. But computed tomography and MRI playing an increasingly important role in the diagnosis, in determination of the malignant transformation and planning the surgical approach.

[Eagle syndrome: case report].

Eagle's syndrome, also known as elongated styloid process, is an entity that may be the source of craniofacial and cervical pain. It is frequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of Oropharyngeal and Maxillofacial diseases. The paucity of information in the radiologic literature prompted this report.

[Spontaneously hyperdense intracranial epidermoid cyst].

Intracranial epidermoid cysts are relatively rare tumors. These cysts are generally nearly isodense to CSF at CT and nearly isointense to CSF on T1W and T2W MR imaging. Spontaneously hyperdense epidermoid cysts are exceptional. We report the case of a 12-year-old girl with a spontaneously hyperdense epidermoid cyst of the posterior fossa presenting with focal neurological symptoms. The diagnosis was confirmed at histological examination.

Imaging features of spinal epidural cavernous malformations.

Cavernous angioma or cavernoma is a vascular malformation that may affect any area in the neuraxis. Epidural location is very rare and therefore seldom considered in the differential diagnosis of spinal cord compression. We report two cases of epidural cavernous angiomas. The first case is a solitary and purely epidural dorsal cavernous angioma without foraminal expansion or bone modification causing spinal cord compression in a 35 year old woman. The second case is a solitary epidural dorsal cavernous angioma with foraminal extension causing spinal cord compression in a 56 year old woman. Histological confirmation is available for both cases. We describe the MRI features of this lesion insisting on its differential diagnosis on imaging.
