Magnetic resonance imaging (MRI) showed solid intra- and suprasellar lesions with hypoenhancement after the administration of the contrast medium [Figure 1].
Magnetic resonance images and CT images after neurological and hormonal symptoms appeared. Upper left and center: T1-weighted images, upper right: T2-weighted image. Middle left and center: T1 weighted images after administration of contrast medium showing enhancement of the outline of sellar lesion. Lower left and center: CT image showing intra- and supra-sellar enhanced mass lesions, defect of the sella floor, and extension of the pituitary lesion toward the shpenoid sinus.

After the administration of the contrast medium, the prominent rim enhancement extending toward the sphenoid sinus was seen [Figure 2].
Intra-operative endoscopic view. The lesion consisted of the yellowish-white thick creamy pus extending toward the sphenoid sinus through the defect of sellar floor.

The sellar floor was destroyed and yellowish-white creamy pus was observed [Figure 3].
Microphotogram: Histopathology suggestive of pituitary adenoma with inflammatory cells. Hormonal immunohistochemistry was negative (H & E, x200).

A histopathological study with hematoxylin and eosin staining revealed hypostaining adenoma cells with round nuclei and acidophilic cytoplasm, and inflammatory cells [Figure 4].
Magnetic resonance images after treatment. Upper right and center: T1-weighted images, upper left: T2-weighted image, lower right and center: T1-weighted images after administration of contrast medium. Abscess and tumor were almost totally excised.

Neurological and general findings were improved, and MRI revealed complete evacuation of abscess and removal of the tumor [Figure 5].
