This year, we welcomed our newest neurosurgeon – Dr. Igor DeCastro. His level of experience and depth of knowledge adds to our incredibly robust team of physicians. We invite you to discover more about Dr. DeCastro and how his passion to help people made him into the neurosurgeon he is today!
Macon, GA, July 30, 2018 – Georgia Neurosurgical Institute (GNI), with practice locations in Macon, Warner Robins, Dublin, Milledgeville, Griffin and Locust Grove, today announced the recent collaboration of GNI vascular neurosurgeon Arthur Grigorian, MD and previous GNI Research Fellow Tigran Khachatryan to create a device that will be used across the globe for the purposes of neurosurgical education.
Spondylolisthesis is a condition where instability in the spine is present due to a slipped vertebra. If the vertebra has slipped a considerable amount, you will likely feel lower back pain and leg pain. This can make everyday activities very difficult. Fortunately, the GNI physicians can help!
Laser spine surgery refers to surgery that is aided by a laser. Whether it’s due to sci-fi movies or false information floating around on the Internet, many people mistakenly believe that laser spine surgery is top-notch, second-to-none, and the pinnacle of surgery greatness.
There are many different types of tremors; however, essential tremor (ET) is the most common tremor that is found in adults. It is most often found in adults over 40-years-old and can increase in severity over time.
Medulloblastoma (MB) is an embryonal tumor. Most cases in this age group (adults) occur between the third and the fourth decade with a higher incidence in males. MB is associated with many familiar cancer syndromes, but there is no known cause for MB. Prenatal exposure to dietary N-nitroso compounds increases the risk. John Cunningham polyomavirus (JC Virus) T-antigen was identified in MB cells, suggesting a role of this viral infection in tumor physiopathology.
In the pediatric group, MB is the most common malignant brain tumor, but accounts for less than 1% of all adult intracranial tumors,[ 11 5 ] with an annual incidence of approximately only 0.5 per million individuals. Many studies have documented the differences between childhood and adult MBs in terms of location, histological subtypes, as well as the proliferation and apoptotic indices. There are four histological groups – classic and the variant forms (desmoplastic/nodular, anaplasic, and large cell), with desmoplastic/nodular being the most frequent variant. Transcriptional profiling studies have shown that MB is not a single disease. There are four major subgroups according to molecular configuration: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4. These subgroups carry different prognostic outcomes and should be noted when planning the treatment strategy. The studies related to tumor biological and clinical features in adults are limited due to the low incidence of the disease in this age group. This article aims to briefly review the available literature and report a case of MB in a 19-year-old woman.
Currently, microscopic or endoscopic transsphenoidal surgery (TSS) is the preferred method for the treatment of intrasellar pituitary adenomas.[13,17,19,32] Approximately 1,650 cases of TSS are performed annually for removal of pituitary adenomas in the United States.[1,29] One of the preoperative considerations for TSS is an exclusion of “kissing internal carotid arteries: (ICA), a rare anatomical variant and absolute contraindication for TSS.[25,28,38] However, even in the absence of this vascular configuration, the rate of intraoperative arterial injuries remains significant. In different case series, it has been reported to be as high as 1.1%.[2,8,9,14] Thus, the imputed number of iatrogenic vascular injuries encountered during TSS in the United States is approximately 18 cases per year, which is a significant cause of morbidity and mortality as well as physician liability. These injuries are mainly attributed to direct iatrogenic injury to the ICA.[3,18,25,39] However, there is some evidence suggesting that coincidental intracranial aneurysms are found almost seven times more frequently in pituitary adenomas when compared to other intracranial neoplasms. The exact cause of this augmented incidence still remains unclear; however, it raises concern about encountering an ICA aneurysm during TSS, which in some cases may lead to hemorrhagic complications.
We present a case of a patient who was found to have a growth hormone (GH)-secreting pituitary adenoma and a coexisting cavernous ICA aneurysm embedded within the tumor. The patient underwent medical treatment of the adenoma. However, shrinkage of the tumor resulted in simultaneous enlargement of the observed aneurysm warranting endovascular intervention.

The network of vessels within your body is known as your vascular system. How well your vascular system is maintained directly affects your quality of life. Fortunately, there are ways to keep your blood vessels healthy and functioning properly. But, if your vascular health is poor, the GNI neurosurgeons are here to help.
At Georgia Neurosurgical Institute, we have innovative technology and highly-trained surgeons who can lead you on your road to recovery.
