Objective:
To study diagnosis and differential diagnosis of Kallmann syndrome.
Methods:
The examinations including routine karyotyping, sex hormone, GnRH stimulation test and MRI were performed.
Results:
Cytogenetic analysis of his peripheral lymphocyte by G banding showed a normal male karyotype. GnRH stimulation test presented a good reaction. Plasma levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone were very low. Absent olfactory bulb was found by magnetic resonance imaging (MRI).
Conclusion:
Karyotype analysis, sexual hormone, GnRH stimulation test and MRI are very important the diagnosis of Kallmann syndrome.
