[Diagnosis and differential diagnosis of Kallmann syndrome].
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).


CONCLUSIONS
Karyotype analysis, sexual hormone, GnRH stimulation test and MRI are very important the diagnosis of Kallmann syndrome.
