Brain MRI may be helpful in the diagnosis of delayed puberty. Findings on MRI suggestive of delayed puberty include hypothalamo-pituitary lesions, aplasia of olfactory bulb and/or sulci (Kallmann syndrome), optic nerve compression (pituitary adenoma), and inner ear abnormalities (CHARGE syndrome). Showing the aplasia of olfactory bulbs and/or sulci in MRI, it is assumed as differentiation of Kallmann syndrome from isolated hypogonadotropic hypogonadism, in the patient without smelling problems or hard to evaluate.

- Brain MRI may be helpful in the diagnosis of delayed puberty. Findings on MRI suggestive of delayed puberty include:[2]
- Hypothalamo-pituitary lesions
- Aplasia of olfactory bulb and/or sulci (Kallmann syndrome)
- Optic nerve compression (pituitary adenoma)
- Inner ear abnormalities (CHARGE syndrome)
- Brain MRI is indicated in patients with delayed puberty, experiencing some alarm signs, such as headache, visual impairment, and behavioral changes.
- Showing the aplasia of olfactory bulbs and/or sulci in MRI, it is assumed as differentiation of Kallmann syndrome from isolated hypogonadotropic hypogonadism, in the patient without smelling problems or hard to evaluate.[3]
- A moderate agreement is seen between the smell identification test (UPSIT) and presence of the olfactory bulbs in MRI, in patients with hypogonadotropic hypogonadism. While there is a good agreement between them in absence of the olfactory bulbs in MRI and anosmia.[4][3]
