case_images: Enhanced magnetic resonance imaging (MRI) of the patient's head: (A) Coronal view of the gadolinium-enhanced T1-weighted image showing a spherical enhancing mass in the right frontal convexity and a dural tail sign. A round low-intensity lesion can be seen on the right side of the pituitary gland, and the pituitary stalk is displaced to the right. (B) Sagittal T1-weighted sequence with contrast showing the degree of enhancement is lower than that of the pituitary in the sellar region.

case_images: T1-weighted MRI with contrast enhancement showed a spherical enhancing mass (3.0 cm x 3.0 cm) in the right frontal convexity and a dural tail sign (Figure 1A). In the sellar area, the enhancement degree of the lesion (7.8 mm x 6.4 mm) was significantly lower than that of the surrounding pituitary tissue, and the pituitary stalk was displaced to the right (Figure 1A and B).
case_images: (A) Histopathologic examination revealed a pituitary adenoma (Hematoxylin and eosin staining, 100x). (B) Histopathologic examination revealed a meningioma (Hematoxylin and eosin staining, 100x).

case_images: The pathological specimen was examined and was determined to be consistent with a pituitary microadenoma (Figure 2A). Histological examination revealed a WHO grade I meningioma (Figure 2B).
case_images: Abdominal appearance with striae (A) preoperation and (B) 4 months postoperation.
