[Misdiagnosis in isolated sphenoid sinus diseases]
1Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Peking University, Beijing 100034, China.
Objective:
To improve the correct diagnosis for isolated sphenoid sinus diseases.
Methods:
Twelve patients with isolated sphenoid disease from 1991 to 1998 were reviewed. The factors of misdiagnosis were discussed.
Results:
In this group of 12 patients with isolated sphenoid diseases, 8 failed to be diagnosed at the first time of medical consultation. The misdiagnosis included optic neuritis, neuralgia, ophthalmitis, pulmonary tuberculosis, epistaxis and epilepsy.
Conclusions:
The main causes of misdiagnosis were: low incidence of the disease, nonspecific clinical symptoms, and unawareness of the doctor. CT or magnetic resonance imaging (MRI) can provide much more informations about the diagnosis.
