Pituitary Tumor Removal

Southern California Pituitary Surgeon, Robert Louis MD, recounts a successful Pituitary Tumor removal recent surgery case

The case illustrates challenges and comprehensive evaluation of Pituitary Tumor identified after loss of peripheral vision


A 33-year-old female patient approached Orange County Neurosurgeon Robert Louis MD with three month history of headache, fatigue and visual loss.


An MRI scan demonstrated a 3 cm Pituitary Tumor compressing the normal pituitary gland and optic chiasm. The symptoms included loss of vision and loss of hormone function, such as fatigue and bouts of headache. Additional ophthalmological examination revealed she had a loss of peripheral vision. Hormonal testing further revealed low thyroid hormone and growth hormone levels in her body.


The patient underwent Endoscopic Endonasal Transsphenoidal, a Minimally Invasive Keyhole Brain Surgery for the removal of tumor. She was discharged home on post-operative day two without complications.


Three weeks later, the patient was back to work and feeling great. An overall improvement in vision and visual fields was noted following Endoscopic Endonasal Transsphenoidal procedure. Her hormonal function also recovered completely. Post-operative MRI demonstrated complete tumor removal. She has returned to normal life with her husband and two young children.
