in 2008 retrospectively analyzed clinical record data for 42 adult patients who underwent surgical resection of pituitary
microadenoma.
Intrasellar carotid anastomosis simulating pituitary
microadenoma.
Magnetic resonance imaging showed one patient with
microadenoma and seven with macroadenoma [Table 1].
If pituitary adenomas are smaller than 10 mm, they are classified as
microadenoma and they are generally functional.
Most common tumour observed in the study was pituitary macroadenoma in 20 cases, followed by 8 cases of craniopharyngioma, then 6 cases of
microadenoma and 5 cases of meningioma and one case was an aneurysm of supraclinoid ICA which was mistaken for meningioma on CT and later diagnosed to be aneurysm on MRI.
Symptoms of a pituitary
microadenoma may include tiredness, headaches, vomiting, dizziness, vision problems, and menstrual or breast changes (Barrow Neurological Institute, n.

A los 13 anos de edad en los estudios hormonales evolutivos del eje hipotalamo- hipofisario, detectan cifras bajas de hormona de crecimiento, lo que condujo a la realizacion de una tomografia contrastada selectiva de la silla turca, diagnosticandose por estas imagenes un
microadenoma de hipofisis, el medico endocrinologo que atendia a esta paciente decidio indicar tratamiento hormonal con GH (hormona de crecimiento) con una frecuencia diaria durante 3 meses, al termino de este tiempo la paciente comenzo a presentar trastornos visuales, por lo cual se le indico una nueva tomografia contrastada selectiva de la silla turca, donde se aprecia una lesion compatible con un macroadenoma de hipofisis, por lo cual se decidio interconsultar con Neurocirugia para su tratamiento quirurgico.
