My prolactins level were high and doctor suggested MRI These are the findings "There is an ovoid nodule measuring 6.6 x 8.8 x 5.7 mm (AP x TR x CC) seen in pituitary gland on left side, which appears isointense on T1, heterogeneously hyperintense on T2, hypoenhancing on early phase of dynamic contrast images and intense homogeneous contrast enhancement on delayed images of dynamic study. Pituitary stalk is deviated towards right side. Imaging findings are suggestive of pituitary microadenoma. Serum prolactin estimation is suggested." I am very worried, what does it mean ?
