Matthew J Gutman, Elena How, Teresa Withers
BACKGROUND: The "floating anchored" craniotomy is a technique utilized at our tertiary neurosurgery institution in which a traditional decompressive craniectomy has been substituted for a floating craniotomy. The hypothesized advantages of this technique include adequate decompression, reduction in the intracranial pressure, obviating the need for a secondary cranioplasty, maintained bone protection, preventing the syndrome of the trephined, and a potential reduction in axonal stretching...

BACKGROUND: Lesions of the petroclival fissure are difficult to access surgically. Both retrosigmoid and presigmoid retrolabyrinthine approaches have been described to successfully treat these complex tumors. The retrosigmoid approach offers quick and familiar access, whereas the presigmoid retrolabyrinthine approach reduces the operative distance and the need for cerebellar retraction. The presigmoid retrolabyrinthine approach, however, is constrained by anatomical limits that can be subject to patient variation...

BACKGROUND: Tuberculosis is a very common disease in India. Its prevalence, capacity to affect every other organ, and atypical presentations make it an important part of the differential diagnosis for cases presenting in the rural setup. Primary tuberculous caries of the calvarium is a rare manifestation of this common entity. CASE DESCRIPTION: A young lady presented with headache and discharging sinus of the scalp. Imaging revealed epidural abscess with midline shift...

BACKGROUND: Trigeminal neuralgia (TN) is the most common type of facial neuralgia with incidence of 26.8/100,000 person year. In general, this scenario is characterized by a lancinating, unilateral, paroxysmal pain in the area of the fifth cranial nerve. Several treatment methods, including the injection of ethyl alcohol or butyl alcohol into the ganglion, the glycerol injection into the trigeminal cistern, peripheral nerve divisions, the radiofrequency thermocoagulation of the preganglionic fibers, and radiosurgery has been used for TN...

Eric Marvin, Asad S Akhter, Jeroen R Coppens
BACKGROUND: Hemangioblastomas (HGBs) are the most common primary intra-axial posterior fossa tumor in adults. Although spontaneous hemorrhage of these tumors is exceedingly rare, despite their vascular nature, we describe a case of recurrent hemorrhage with associated tonsillar herniation, and demonstrate that a surgical approach can provide a suitable outcome. CASE DESCRIPTION: A 54-year-old female with von Hippel-Lindau (VHL) syndrome presented with acute loss of consciousness and Glasgow Coma Scale (GCS) was 4...

BACKGROUND: As far as public health is concerned, brain tumors burden is significant despite their low incidence, because they comprise high direct costs (specific diagnostic resources, high complexity treatments, and rehabilitation) and high-unforeseen costs (labor leave, family, and social issues). Although the Argentine's Health System is supposed to provide healthcare to all the population, it would not guarantee equity of access for brain tumors treatment. In order to analyze this hypothesis we decided to carry out a survey to obtain data on access, availability and resources for tumor management in Argentina...

BACKGROUND: Middle cerebral artery (MCA) aneurysms constitute from 18-40% of all intracranial aneurysms. They are mainly found in the proximal and bifurcation tracts and only in the 1.1-1.7% of cases they are located in the distal segment. The authors report a case of a ruptured saccular cortical MCA aneurysm with unknown etiology. CASE DESCRIPTION: A 53-year-old female was admitted with a sudden severe headache, nausea, vomiting, and a slight left hemiparesis. The computed tomography (CT) scan showed subarachnoid hemorrhage (SAH) in the left sylvian fissure and intracerebral hemorrhage (ICH) in the left posterior parietal area...

#16
Sidra Sattar, Naveed Z Akhunzada, Gohar Javed, Zeeshan Uddin, Yasir A Khan
BACKGROUND: Pilocytic astrocytoma (PA) is the most prevalent central nervous system (CNS) tumor in pediatric population and accounts for an approximate of 5-6% of all gliomas. This neoplasm can occur at all levels of the neuraxis, with majority (67%) arising in the cerebellum and optic pathway. PAs are World Health Organization Grade I tumors and are the most benign of all astrocytomas characterized by an excellent prognosis. Other differentials include subependymal giant cell astrocytoma (SEGA), ependymoma, meningioma, and low-grade gliomas such as pilocytic or diffuse astrocytoma; calcification is more commonly regarded as a feature of benign or slow-growing tumors...

Nouman Aldahak, Derrick Dupre, Mohamed Ragaee, Sebastien Froelich, Jack Wilberger, Khaled M Aziz
BACKGROUND: Retromastoid craniectomy (RSC) is a cardinal surgical approach used to access the posterior fossa. Hydroxyapetite bone cement (HBC) is frequently employed for cranioplasty in efforts to prevent cerebrospinal fluid (CSF) leak, whilst maintaining low complication rates and good cosmetic satisfaction. The authors aim to determine the safety and effectiveness of HBC for reconstruction RSC used for treatment of various cranial nerves disorders. METHODS: The authors conducted a retrospective one-center two surgeons review of 113 patients who underwent RSC filled with HBC for the treatment of cranial nerve disorders...

BACKGROUND: Isolated hypoglossal nerve palsy due to mechanical compression by a vascular lesion is rare. CASE DESCRIPTION: We report the case of a 72-year-old man who presented with a 4-year history of swallowing disturbance and subsequently progressively worsening left-sided tongue atrophy. He was referred to our department by a neurologist due a magnetic resonance imaging detected left vertebral artery compression of the medulla. Neurological examination was unremarkable except for left hypoglossal nerve dysfunction, which presented as left-sided atrophy and impaired movement of the tongue...

BACKGROUND: While it is a rare entity, spinal angiolipomas are well-defined benign tumors that have been described sporadically in the literature starting from the late 1800s. Composed of mature lipomatous and angiomatous elements, these tumors manifest neurological symptoms due to progressive spinal cord or root compression. We present a case of a thoracic spinal angiolipoma and review the relevant literature. CASE DESCRIPTION: A 68-year-old male with ongoing bilateral lower extremity weakness was found on enhanced magnetic resonance imaging to have an extradural mass in the thoracic spine causing cord compression...

BACKGROUND: Animals held in captivity tend to live longer than do their wild counterparts, and as such, are prone to developing age-related degenerative injuries. Here, we present a case of an adult female polar bear with symptomatic lumbar stenosis. There is a paucity of literature on large mammalian spine surgery, and anatomical differences between humans and other vertebrates must be taken into consideration. CASE DESCRIPTION: A 24-year-old female polar bear residing at the zoo was found to have decreased motor function in her hind legs...
