„Erler-Zimmer GmbH & Co. KG 3D model of pituitary adenoma:
- Model code: MP2006
- Clinical history
- A 29-year-old man presented with headaches and blurred vision of 22 months duration.
- Examination showed bilateral hemianopsia and left VI nerve palsy.
- Skull X-rays showed that most of the sphenoid body is eroded, while some of the dorsum sellae and anterior clinoid process are preserved.
- Carotid angiography showed overweight and lateral repositioning of the blanket and middle cerebral arteries.
- Pneumoencephalography showed elevation of the lateral and third ventricles from below.
- A craniotomy was performed, but the patient died immediately afterwards.
- Pathology
- The brain sample is cut horizontally at the right falx cerebri, which remains in situ.
- The completely replaced pituitary gland is a round tumor with a maximum diameter of 4 cm.
- The cut surface of the tumor is pale brown and homogeneous (except for an area of hemorrhage at the top, likely caused by surgical trauma).
- The tumor caused the midbrain to lift.
- Tumor erosion has destroyed the sphenoid bone; therefore, the sella turcica is enlarged.
- The optic chiasm is compressed by a tumor.
- Histologically, this tumor was a chromophobe adenoma originating from the anterior pituitary.

- This sample is from an old case, and the testing procedures used would be considered ancient.
- Modern investigations now include an initial CT scan of the brain followed by an MRI scan of the head to better visualize the pituitary focus before any surgical intervention.
