Magnetic resonance imaging (MRI) of the pituitary, hypothalamus and olfactory sulci was performed in 40 patients with idiopathic hypogonadotropic hypogonadism (IHH). Twelve of these patients had an impaired sense of smell (Kallmann's syndrome). Sagittal and coronal imaging revealed no morphological abnormalities in the hypothalamic-pituitary region. On axial imaging rudimentary, hypoplastic or aplastic olfactory sulci were found in eight cases. All patients with olfactory sulcal abnormalities had associated hyposmia (one case) or anosmia (seven cases). Structural defects identifiable on MRI were present only in 20 per cent of patients with IHH.
对40例特发性低促性腺激素性性腺功能减退（IHH）患者进行了垂体、下丘脑和嗅沟的磁共振成像（MRI）检查。其中12例患者嗅觉减退（卡尔曼综合征）。矢状位和冠状位成像显示下丘脑 - 垂体区域无形态学异常。轴位成像发现8例嗅沟发育不全、发育不良或未发育。所有嗅沟异常的患者均伴有嗅觉减退（1例）或嗅觉丧失（7例）。MRI上可识别的结构缺陷仅在20%的IHH患者中出现。
