case_images: Magnetic resonance imaging, T1 post-gadolinium. (A) Coronal view and (B) Sagittal view. A 3 x 4.6 x 3.7 mm microadenoma is observed (red arrow).

case_images: T1-weighted images following gadolinium administration, measuring 3 x 4.6 x 3.7 mm, consistent with a microadenoma. The pituitary stalk showed a slight deviation to the left (Figure 1).
case_images: MRI, (A) T1 coronal view without contrast and (B) T2. An increase in tumor size is observed, measuring 12 x 19 x 11 mm. with intratumoral bleeding.

case_images: The pituitary stalk was no longer visible, and there was no evidence of cavernous sinus invasion; however, intratumoral bleeding was observed (Figure 2).
case_images: MRI without contrast. (A) T1 coronal view, (B) T2 and (C) T1 sagittal view. An increase in the size of the prolactinoma is observed, measuring 17 x 21 x 13 mm, compressing the chiasm. Presents fluid level and is hyperintense on T1 compatible with bleeding.

case_images: This scan revealed further enlargement of the adenoma to 17 x 21 x 13 mm, accompanied by hemorrhage within the pituitary lesion (Figure 3).
case_images: Magnetic resonance imaging, T1 post-gadolinium. (A) Coronal view and (B) Sagittal view. No evidence of the prolactinoma is seen.

case_images: Subsequently, the patient resumed regular menstrual cycles, prolactin levels normalized, and there was no evidence of tumor remnant on MRI (Figure 4).
