Older gentleman notes progressive vision decline, double vision, and pain over the left temple for the past few months. Further work up reveals a large tumor growing into the compartments of the temple, jaw, brain, and eye.

He was taken to surgery for complete removal of the mass with reconstruction of the bone over the eye and temple which had been eaten away by the tumor.

After surgery his vision improved and he was discharged home after 4 days recovery in the hospital.

Spheno-orbital meningioma is a rare, slow-growing tumor that starts on the sphenoid bone at the base of the skull and extends into the eye socket

Common Symptoms

Proptosis: The eyeball bulges forward because the tumor takes up space in the eye socket.

Visual impairment: Blurry vision or loss of sight can happen if the tumor presses on the optic nerve.

Diplopia: Double vision occurs when the tumor blocks the muscles that move the eye.

Headaches: Pain or pressure builds up around the eye and temple area.

Middle age woman presents with 4 months of double vision. She was found to have a skull base tumor that was compressing the brainstem / pons. She underwent surgery through the nostrils for total resection of the tumor. Post operatively her double vision improved.

Endoscopic (using a long camera) endonasal (surgery through the nose) approach is a minimally invasive surgical technique that uses the nostrils and nasal cavities as natural pathways to reach and remove tumors or lesions at the base of the skull or the top of the spine.

At our skull base center of excellence, neurosurgeons work together with otolaryngologists (ear, nose, and throat specialist) to precisely dissect and remove the tumor without needing external facial cuts

Main Benefits:
No External Scars: Because instruments pass completely through the nose, there are no visible incisions on the face, head, or scalp.

No Brain Retraction: Surgeons can access deep-seated midline lesions directly from below, avoiding the need to push aside or move healthy brain tissue.

Faster Recovery: Patients often experience less post-operative pain and enjoy a quicker return to normal daily activities compared to traditional open skull surgery.

Middle age woman with high blood pressure was found down by family unable to speak and unable to move the right side of her body. She was brought into the ER where a CT showed a large bleed in the left basal ganglia.

She was taken urgently to the operating room where through a 1 cm burr hole, the hematoma was evacuated. Day after surgery she started to say one or two word sentences and was able to move her leg. At 3 month follow up she regained the ability to walk and was speaking more fluently.

For those of you who work in this space, you'll recall that prior to 2015 there were countless studies showing how removing blood clots from patient's arteries during an acute ischemic stroke was "futile". Many neurologists and neurosurgeons around the world thought stroke was untreatable and only preventable. Luckily, not everyone gave up because some of us saw the benefits first hand. Fast-forward to today, once we determined the optimal patient and timing of intervention, aspiration of clot for treatment of acute ischemic stroke has become the standard of care.

Similarly for large bleeds in the brain, historical and contemporary data show that these patients do not benefit from surgery. However, minimally invasive treatments have shown promise and I truly believe there is benefit to this operation. The question remains who is the optimal patient and what is the optimal timing of intervention.

Hopefully those of us who see the benefit of this operation won't give up on our patients. Neurosurgery is about accepting challenges and pushing boundaries.

Young man presents with sudden paralysis of the left arm and leg, facial droop, double vision with difficulty moving his eyes, and difficulty speaking. He was evaluated in the ER and found to have acute bleeding within the brainstem in the pons.

Initially he was diagnosed with a hemorrhagic stroke and thought to be due to high blood pressure; however, follow up imaging a week later showed continued enlargement of the bleed.

Due to the patient's age, I suspected that there was an underlying blood vessel mass called a cavernous malformation, which is like a hemorrhoid of the brain / tangle of fine blood vessels that can become engorged and cause local bleeding and damage.

The patient underwent urgent surgical resection of the mass due to progressive bleeding. The patient tolerated the procedure well. Post operatively he started to regain the movement in his arm and leg and by 6 weeks follow up he was walking without assistance and was able to hold a fork and eat with his left arm. He still had some double vision but this was also improving. Imaging shows a brainstem pontine cavernoma before and after surgical resection.

Middle aged woman presents with progressive headaches along the top of her head. She has had on and off headaches for a few years but over the past few months they have become more frequent and severe. Further evaluation reveals a brain aneurysm located near the top and front her of head.

Due to her risk factors as well as the aneurysm characteristics, she wished to have preventative treatment of the aneurysm.

The aneurysm has a relatively wide neck and would have historically been best treated with surgical clipping or stent assisted coiling; however, the patient wanted a minimally invasive option but was hoping not to need blood thinners and therefore wanted to avoid a stent.

To work around these considerations, a newer device called the WEB (woven endo bridge) device was thought to be the best option. The WEB is a acts like a pre-shaped plug and works by blocking blood flow along the aneurysm neck and can be placed without the need for heavy duty blood thinning medications.

The patient underwent the procedure which was performed via a puncture in the wrist and a WEB device was delivered to occlude the aneurysm. The patient tolerated the procedure well and was discharged home the following day.

Young woman presents with couple month history of a loud annoying whooshing sound in her right ear. She developed this after heavy lifting and straining. It took almost a year but she was ultimately diagnosed with a spinal fistula.

Although most spinal fistulas present with progressive, slowly developing insidious neurological deficits (usually leg weakness, poor balance, and numbness or tingling). This occurs usually due to congested veins. The spinal cord in lack of a better term "becomes constipated" and malfunctions or has sudden bleeding inside the spinal cord or canal.

Rarely spinal fistulas especially higher up in the neck, can present with pulsatile tinnitus or a constant whooshing in the ear and are often missed on initial evaluation as most people focus on the ear or the brain.

The patient underwent an awake occlusion of the vertebral artery venous fistula which fed directly into the venous plexus at multiple segments within the vertebral artery. Imaging shows before and after treatment.

She tolerated the procedure well and was discharged home the next day. At 3 months follow up she had no neurological symptoms and her whooshing went away.
