ABSTRACT
Nonsquamous tumors of the nose and paranasal sinuses are an uncommon group of neoplasms. Information is only available from case reports and short series. Therefore, conclusions concerning natural history and response to therapy are uncertain for tumors in these sites. The need for complete and timely evaluation of new and changing clinical signs must be emphasized. For each tumor, maximal interaction among the clinician, radiologist, and pathologist is needed to reach the correct diagnosis and plan effective therapy. This interaction is especially important for the deceptively benign-appearing tumors listed in Table 2. These tumors behave biologically in an unpredictable fashion, and long-term follow-up is mandatory.

Nonsquamous cell tumors of the head and neck can be reliably identified and often accurately diagnosed by proper state of the art radiologic assessment. For optimal diagnostic and preoperative work-up of head and neck lesions, complete radiologic analysis is now essential.

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.
