Emergency presentation of coalescent mastoiditis.

Since the introduction of sulfonamides in the late 1930s, coalescent mastoiditis is an uncommon complication of otitis media. Swelling, erythema, and tenderness over the mastoid area with associated anterior displacement of the auricle are classic signs and symptoms of coalescent mastoiditis with formation of a subperiosteal abscess. Early recognition of this entity is essential to prevent its complications. Prompt otolaryngologic consultation is indicated and inpatient antibiotic therapy should be begun. Surgical treatment is also needed and may obviate further complications.

A case of vocal cord nodules masking essential (voice) tremor.

Essential tremor is a progressive, potentially debilitating disorder that may be manifested in the voice only. In the case we report, the signs occurred concurrently with the voice characteristics of vocal cord nodules but were subtle. The mildness of the voice tremor precluded treatment at this time, although the results of medical management for the disorder have not been impressive. It is probable that some patients with severe essential (voice) tremor have undergone recurrent laryngeal nerve resection for the disorder.

Angiography in the diagnosis and management of extracranial vascular lesions of the head and neck.

The angiographic features of various lesions of the head and neck are presented. Angiographically, cavernous hemangiomas display large venous lakes with calcified phleboliths. Arteriovenous malformations reveal massive tumor stain with well delineated feeding vessels from multiple systems. Chemodectomas and juvenile nasopharyngeal angiofibromas are clearly vascular with homogenous tumor staining in the capillary phase. Angiography of cavernous hemangioma, AVM, chemodectoma, and angiofibroma is diagnostic and may preclude the need for tissue biopsy. Angiographically neurilemmomas are less vascular with non-homogenous tumor stain. Carcinomas are typically avascular. The use and benefits of arterial embolization in the management of these lesions is presented.
