The Relationship between Reoperative Prognostic Nutritional Index Levels and Risk of In-Stent Restenosis following Cerebrovascular Bare-Metal Stent Implantation
Qiang Fang, Yun Yang, Jiajun Wei, Ligen Fan, Zhuoxi Xie, Zhouming Zhu and Hao li
Article Type: Clinical Research | First Published: May 27, 2021
In-stent restenosis (ISR) is a key parameter influencing long-term stent use in patients that have undergone cerebrovascular stent implantation, and it additionally impacts surgical treatment outcomes. Inflammation is a key driver of ISR incidence, To date, however, no studies have evaluated the relationship between ISR and prognostic nutritional index (PNI), which is based upon lymphocyte counts and serum albumin levels and is closely linked with inflammatory activity. In this study, we therefo...

Multilevel Percutaneous Vertebroplasty with the Spine Jack® System in a Patient with Cushing Disease
Cuauhtemoc Gil-Ortiz, Alberto Ramírez-Romero, Javier Lagos-Servellon and Dulce Bonifacio- Delgadillo
Article Type: Clinical Case | First Published: June 28, 2021
Percutaneous vertebroplasty (PV) is a minimally invasive procedure that requires the injection of cement into a fractured vertebral body. Spine Jack® is a vertebroplasty system with an intracorporal implant designed to restore the height of the vertebral body in osteoporotic vertebral fractures. There are no reported cases of PV with Spine Jack® system as treatment for multilevel compression fractures in patients with vertebral osteoporosis due to Cushing disease. A 55-year-old male with lumba...

Partially Thrombosed Giant Posterior Inferior Cerebellar Artery Aneurysm Mimicking a Fourth Ventricular Tumour
Taofiq Sanusi, William Owiti, Juraj Schwab and Ashraf Abouharb
Article Type: Case Report | First Published: June 24, 2021
Posterior circulation aneurysms are less common compared to the anterior circulation aneurysm. Dissection distal Posterior Inferior Cerebellar Artery, PICA, aneurysm is very uncommon. In this case report, we describe an adult who had distal PICA aneurysm in the 4th ventricle which radiologically and symptomatically mimics a fourth ventricular mass lesion. Our aim is to add to the literature about rare but possible differential diagnosis of 4th ventricular tumour. A 43-year-old lady presented wit...

Spontaneous Intracystic Hemorrhage in an Adult with Cerebellopontine Angle Arachnoid Cyst and Management: A Case Report
Joel Passer, MD, Anand Kaul, MD and Rami O Almefty, MD
Article Type: Case Report | First Published: June 24, 2021
Arachnoid cysts are common findings on neuroimaging and account for approximately 1% of all intracranial lesions. The cerebellopontine angle is the second most common location. When arachnoid cysts become symptomatic due to cyst growth, or rarely, cyst rupture, they create mass effect on adjacent neurovascular structures and may require neurosurgical management. This involves a posterior fossa decompression and cyst fenestration with or without cyst fluid diversion. We present a case of a 40-yea...

Resolution of Asymptomatic Significant Volume Extradural Haematoma on Clinico-Radiological Assessment: A Case Report
Krishan Kumar Sharma and Asgar Ali
Article Type: Case Report | First Published: June 18, 2021
According to guidelines of the brain trauma foundation and the congress of neurological surgeons for managing traumatic brain injury, surgical evacuation recommended for extradural haematoma with volume more than 30 cm3 regardless Glasgow coma scale (GCS) of patient. A case of asymptomatic extradural haematoma (volume 40.5 cm3) treated on regular clinico-radiological assessment (CRA) showed near complete resolution of extradural haematoma. This supports CRA as an ethically justified treatment ap...

Flow Related Aneurysm in Hemangioblastoma and Literature Review of Hemorrhagic Rate and Management Strategy
Choo Heng Tan, FRCS, Felicia HZ Chua, MBBS, MRCS and Peter Y K Hwang, FRACS
Article Type: Case Report and Literature Review | First Published: May 29, 2021
Hemangioblastoma is known to be a vascular tumor although its hemorrhagic rate is low. The association with aneurysm can be due to flow related in highly vascular pathology like hemangioblastoma or secondary to presence of hypoxic induced factor and vascular endothelial growth factor in case of Von-Hippel Lindau syndrome. However, the hemorrhagic rate and management strategy is not well established in patients with co-existence of hemangioblastoma and aneurysm. This is a 60-years-old man who dev...

Article Type: Case Report | First Published: April 23, 2021
Intracranial arachnoid cysts (AC) rarely enlarge and become symptomatic, especially in adults and when located retrocerebellar. This report describes an adult in which an expanding retrocerebellar arachnoid cyst prompted surgical resection and it provides an overview of the literature and recommendations for optimal management. A 65-year-old women was diagnosed with an incidental retrocerebellar AC. She presented 10 years later with headaches, aural fullness and poor balance. Consecutive MRI sho...

Intra-Axial Neurenteric Cyst of Medulla. Case Report and Literature Review

Article Type: Case Report | First Published: April 23, 2021
NECs are rare congenital lesions that are thought to be a result of persistence of the neurenteric canal to arise from a persistent neurenteric canal connecting primitive gut and neural tube. Despite the congenital nature NECs can be diagnosed at any age and at a similar frequency in women and men. To our knowledge, 140 intracranial NC, confirmed by histology, including the patient presented in this review, have been reported since 1952. Parenchymal NCs are extremely rare and there are no any pu...

We present an unusual case of a 60-year-old female who developed subtle, new-onset left upper and lower extremity weakness on day five after perioperative thoracic epidural placement. The onset of a focal neurological deficit in any patient undergoing epidural anesthesia usually raises suspicion for the presence of an epidural hematoma, abscess, or traumatic cord lesion. However, in this patient, brain imaging revealed a large, occult intracranial mass. Classically, the risk of mass related intr...
