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...

Radiologically Documented Enlargement of Retro-Cerebellar Arachnoid Cyst Causing Obstructive Hydrocephalus in Late Adulthood. A Case Report

Florence Constance Maria Reith, MD, PhD, Markus Schmidt, MBBS(Hons), FANZCA and Gabriel Yin Foo Lee, MBBS(Hons), MS, FRACS

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

Andrey Vladimirovich Gavrjushin, MD, PhD and Danil Mihajlovich Chelushkin, MD

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...

Neurologic Deficits after Epidural Catheter Removal Lead to Meningioma Diagnosis

Morgan A Clond, MD, PhD, Evin A Koleini, MD, Timothy E Richardson, DO, PhD, Stephanie A Zyck, MD, Vandana Sharma, MD, Mashaal Dhir, MD, Fenghua Li, MD, Satish Krishnamurthy, MD, Xiuli Zhang, MD and P Sebastian Thomas, MD

Article Type: Case Report | First Published: April 21, 2021

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...
