Abstract
Background
Isolated inflammatory sphenoid sinus disease (IISSD) can be difficult to diagnose. Frequently, history and physical are inadequate in establishing a diagnosis. Computed tomography (CT) is an excellent screening tool; however, it often is obtained late in the disease process because of vague symptoms at presentation. Identifying the most common presenting symptoms of IISSD may allow earlier detection and avoidance of more severe sequelae by determining earlier indications for CT. Presently, headache is not an indication for sinus CT.
Methods
A retrospective chart review of IISSD presentation was performed at our institution. A literature review was performed also to quantitatively document trends in presentation of IISSD, including characterization of headache symptoms by location. Cumulative findings were then compared with current CT indications to determine if presentation patterns warrant a change in indications for CT.
Results
A total of 361 cases were evaluated by our inclusion criteria. Headache was the most common finding (81.7%), particularly peri/retro-orbital, vertex, and frontal headache. Ocular changes (17.5%) and cranial nerve involvement (16.1%) were common also, but headache frequently was a solitary finding (42.6%). Twenty-six IISSD cases were reviewed at our institution over 7 years, with similar results. Under current guidelines, the only IISSD findings that are indications for CT scan are the ophthalmologic and neurological complications.
Conclusion
Not every headache necessitates a CT scan. However, the deep-seated vertex, frontal, and, particularly, peri/ retro-orbital headaches, especially when aggravated by head movement and refractory to analgesics, as is often seen in IISSD, should be an indication for CT evaluation.
