Abstract:
OBJECTIVE:To investigate the causes of misdiagnosis for skull base lesions by PET-CT, and to recognize the working principal and the false-positive results of PET-CT for reducing the misdiagnosis rate.
METHOD:The lesions of case 1 involved the pharynx nasalis, pterygopalatine fossa, and orbital apex base of skull, and the lesions of case 2 involved the base of sella were performed with CT, MRI and PET-CT examination. Both of the cases were treated with surgery and histopathologic examination.
RESULT:Two cases were diagnosed as nasopharyngeal carcinoma and carcinoma of base of sella by PET-CT, respectively. However, they were finally diagnosed mycosis and pituitary tumor by histopathologic examination after operation.
CONCLUSION:PET-CT examination in the skull base lesions may give false-positive result. Both clinical information and other imaging examinations should be considered to reduce the misdiagnosis skull base lesions only by PET-CT.
