A true collision tumor is a rare entity composed of two histologically distinct neoplasms coinciding in the same organ. This paper reports a unique case of cerebral collision tumor consisting of two benign components. On the first hand, meningioma which is usually a benign lesion arising from the meningothelial cell in the arachnoidal membrane. On the other, cerebral cavernoma which is a well-circumscribed, benign vascular hamartoma within the brain. To our knowledge, there is no previously documented case of cerebral collision tumor consisting of two benign components...

Childhood adrenocortical carcinoma (ACC) is a rare tumor and its association with acute lymphoblastic leukemia (ALL) is even rarer. One such case is discussed in this case report. A 3-year-old patient was concomitantly diagnosed with ALL and an initially nonmetastatic ACC. Management started by following the Total XV protocol without a window phase. Left adrenalectomy was conducted after the consolidation phase. Recurrence of a mass at the tumor bed was discovered at week 33 of the continuation phase. Reexcision was conducted, followed by the administration of an ACC protocol including cisplatin, etoposide, and doxirubicin...

BACKGROUND: Growing skull fractures (GSFs) are rare complications of pediatric head trauma that comprise skull fractures associated with an underlying dural tear and an intact arachnoid membrane. They are often misdiagnosed, and delay in management can lead to progression of the disease along with its neurological sequelae. Multiple clinical reports and qualitative reviews on this entity exist. To our knowledge, this represents the largest clinical review reporting on established techniques in the management of these fractures...

BACKGROUND AND PURPOSE: Chronic cauda equina syndrome, defined as persistent damage of the cauda equina nerve roots within the spinal canal can be a challenging diagnosis with varied presentations. MR neurography imaging is more commonly being used to evaluate the lumbosacral spine of patients suspected of having subacute or chronic cauda equina syndrome. Our aim was to evaluate the impact of lumbosacral plexus MR neurography in the diagnostic thinking and therapeutic management of patients presenting with chronic pelvic pain and dysfunction and suspected chronic cauda equina syndrome...

BACKGROUND: Intracranial hypotension secondary to spontaneous spinal cerebrospinal fluid (CSF) fistula is a rare condition which can have serious sequelae. Early diagnosis and treatment can be challenging. CASE DESCRIPTION: We present a case of a 17-year-old man who presented with a history of sudden onset, postural headaches, associated with upper thoracic back pain. Magnetic Resonance Imaging (MRI) demonstrated a thoracic extradural fluid collection and slumping of the brain within the posterior fossa...

Pseudomeningocele is a collection of the cerebrospinal fluid in the extradural space due to a defect in the dura-arachnoid layer of the meninge, and manifests as a fibrous capsule in the space of subcutaneous tissues. Classically, growing skull fracture caused by the pseudomeningocele is not uncommon in the pediatric age group. However, a posttraumatic intradiploic pseudomeningoceles is extremely rare, and only a few patients have been described. Herein, the authors present a 6-year-old girl who developed an intradiploic pseudomeningocele of the occipito-cervical region after a severe head trauma...

BACKGROUND: Cryptococcus can cause meningoencephalitis (CM) among previously healthy non-HIV adults. Spinal arachnoiditis is under-recognized, since diagnosis is difficult with concomitant central nervous system (CNS) pathology. METHODS: We describe 6 cases of spinal arachnoiditis among 26 consecutively recruited CM patients with normal CD4 counts who achieved microbiologic control. We performed detailed neurological exams, cerebrospinal fluid (CSF) immunophenotyping and biomarker analysis before and after adjunctive immunomodulatory intervention with high dose pulse corticosteroids, affording causal inference into pathophysiology...

Motor speech apraxia is a speech disorder of impaired syllable sequencing which, when seen with advancing age, is suggestive of a neurodegenerative process affecting cortical structures in the left frontal lobe. Arachnoid cysts can be associated with neurologic symptoms due to compression of underlying brain structures though indications for surgical intervention are unclear. We present the case of a 70-year-old man who presented with a two-year history of speech changes along with decreased initiation and talkativeness, shorter utterances, and dysnomia...

PURPOSE: The defining feature of glaucoma is excavation of the optic nerve head; however, the mechanism of this loss of tissue is not well understood. We recently discovered a copy number variation upstream of matrix metalloproteinase 19 (MMP19) in a large, autosomal dominant pedigree with a congenital malformation of the optic disc called cavitary optic disc anomaly (CODA). Patients with CODA have abnormal optic discs that exhibit an excavated shape similar to cupping seen in glaucoma...

BACKGROUND: Subdural empyema is a rare form of intracranial infection. It is described as accumulation of purulent infective material between the inner layer of dura mater and outer layer of arachnoid membrane. CASE DESCRIPTION: A 17-year-old girl was admitted to the emergency department with acute left hemiplegia and was diagnosed with interhemispheric subdural empyema that showed a three-fold increase in size within 12 hours. Complete recovery was achieved with emergency surgical evacuation and additional 3 weeks of antibiotic treatment...

OBJECTIVE: To describe a step-by-step approach to the ambient cistern by the suboccipital retrosigmoid supracerebellar infratentorial (RSI) approach. DESCRIPTION: The RSI approach is performed in the same manner as the suboccipital retrosigmoid approach, usually used to access the pathology of the cerebellopontine angle, with the following modifications: (1) we always use the semi-sitting position, (2) the craniotomy-craniectomy must expose the transverse sinus and extend 5 cm medially to the inion, (3) when performing the dural opening it is necessary to mobilize the dura with the transverse sinus upwards, (4) under magnification with surgical microscope the cerebellomedullary cistern should be opened in order to drain cerebrospinal fluid for relaxing the cerebellum, and (5) arachnoidal adherences and bridging veins must be coagulated and cut if necessary...

OBJECTIVE: Spinal arachnoid webs are a rare variant of spinal arachnoid cysts where one or multiple focal membranes of arachnoid tissue obstruct the subarachnoid space. Only 11 prior cases of arachnoid webs have been reported in the literature. Our objective is to present a series of three consecutive cases of arachnoid webs from our institution and to review the literature on this rare condition to provide recommendations for its management. METHODS: A retrospective chart review was performed for three consecutive cases of intradural arachnoid webs causing spinal cord compression at our institution, with inconclusive preoperative imaging, treatment with surgical decompression and resection...

BACKGROUND: Resection of extensive skull base lesions often necessitates relatively large dural openings and arachnoid, resulting in skull base defects with the potential for a post-operative cerebrospinal fluid (CSF) leak. A nasoseptal flap (NSF) is a vascularized graft which has greatly diminished the incidence of CSF leak. Annealing of flaps against the ventral skull base can be tenuous within the first few days after surgery. We report the use of sphenoid sinus fat packing as a buttress to support the nasoseptal flap during skull base reconstruction...

OBJECTIVE: To assess whether computed tomography (CT), magnetic resonance imaging (MRI), and neurosurgical evaluations altered the diagnosis or management of children diagnosed with benign macrocrania of infancy by ultrasonography (US). STUDY DESIGN: We queried our radiology database to identify patients diagnosed with benign macrocrania of infancy by US between 2006 and 2013. Medical records of those with follow-up CT/MRI were reviewed to determine clinical/neurologic status and whether or not CT/MRI imaging resulted in diagnosis of communicating hydrocephalus or required neurosurgical intervention...

The overall incidence of neurological manifestations is relatively low among patients with mixed connective tissue disease (MCTD). We recently encountered a case of autoimmune adhesive arachnoiditis in a young woman with 7 years history of MCTD who presented with severe back pain and myeloradiculopathic symptoms of lower limbs. To the best of our knowledge, adhesive arachnoiditis in an MCTD patient has never been previously reported. We report here this rare case, with the clinical picture and supportive ancillary data, including serology, cerebral spinal fluid analysis, electrophysiological evaluation and spinal neuroimaging, that is, MRI and CT (CT scan) of thoracic and lumbar spine...

INTRODUCTION: Patients with spontaneous sub-arachnoid hemorrhage (SAH) might develop various cardiac abnormalities, however; the prognostic implications of these cardiac abnormalities are not well known. This study aimed to detect the cardiac abnormality that correlates best with in-hospital all-cause mortality in patients with SAH. METHODS: In this retrospective study, all patients admitted to our institution with a primary diagnosis of SAH, and underwent a transthoracic echocardiogram (TTE) from July 2011 until May 2014, were enrolled...
