Adenomatous multinodular goiter causing airway obstruction in an infant

Nontoxic adenomatous multinodular goiter (AMNG) in infants is a rare condition. We discuss an extremely rare case of a nontoxic AMNG in a 3-month-old female presenting with airway obstruction. Surgical resection of the mass was performed to reduce the burden on the airway and for diagnosis. The literature is reviewed, and the clinical characteristics, pathology, and surgical treatment are discussed.

Dynamic computed tomography. Its use in the assessment of vascular malformations and angiofibroma

Reliable diagnostic methods for head and neck vascular lesions are needed. The technique of dynamic computed tomography (CT) is used to delineate two aberrant subclavian arteries, one carotid artery aneurysm, and one angiofibroma. Five or six 4.8-s CT scans were obtained sequentially, separated by a 1.2-s interscan interval. Computer-generated iodinated contrast concentration (CT number) v time curves showed rapid influx of contrast, high peak density, and rapid uninterrupted contrast runoff. Simultaneous bone and soft-tissue visualization at the time of peak contrast enhancement provides excellent delineation of the malformations and angiofibroma. The technique is noninvasive, and it eliminates the potential complications of arteriography and biopsy. We conclude that dynamic CT is an excellent method for diagnosis of head and neck vascular lesions.
