Management of Ruptured and Rapidly Progressive Mycotic Cerebral Aneurysms in the Setting of Unilateral Carotid Occlusion and Endocarditis with Valve Failure
We report a patient with left carotid occlusions, a ruptured left middle cerebral artery mycotic aneurysm, and a rapidly appearing unruptured left anterior cerebral artery/anterior communicating artery (ACA/ACom) mycotic aneurysm in the setting of mitral valve endocarditis with a perivalvular leak and evolving congestive heart failure. Following medical stabilization and antibiotic administration, a combined endovascular (with contralateral access via the ACom) and open surgical approach was used to selectively secure both aneurysms with preservation of distal flow, allowing lifesaving cardiac valve replacement. This case ...

Bilateral Chronic Subdural Nontraumatic Hematoma in a Woman Affected by AL Amyloidosis
We describe the case of a 59-year-old woman affected by AL amyloidosis, harboring surgically treated bilateral chronic nontraumatic subdural hematoma, and we suggest a possible correlation between the clinical entities of CSDH and AL amyloidosis.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Neurological Surgery Reports)

Plasmacytoma of the Clivus Presenting as Bilateral Sixth Nerve Palsy
Conclusion The clivus is an unusual site for intracranial plasmacytomas, and enhancing lesions must be differentiated from chordoma. Characteristic findings on histopathology include an immunoglobulin light-chain restricted clonal proliferation of plasma cells. Treatment is most commonly radiotherapy with surgery reserved for biopsy and palliation. Clinicians should be aware of the increased risk of progression to multiple myeloma in skull base plasmacytomas.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Ne...

Histoplasmosis with Deep CNS Involvement: Case Presentation with Discussion and Literature Review
J Neurol Surg RepDOI: 10.1055/s-0035-1554932Central nervous system (CNS) histoplasmosis is rare and difficult to diagnose because it is often overlooked or mistaken for other pathologies due to its nonspecific symptoms. A 32-year-old Hispanic man with advanced acquired immunodeficiency virus presented with altered mental status and reported confusion for the past 3 months. He had a Glasgow Coma Scale of 12, repetitive nonfluent speech, and a disconjugate gaze with a right gaze preference. Lung computed tomography (CT) findings indicated a pulmonary histoplasmosis infection. Magnetic resonance imaging of the brain revealed ...

Glioblastoma Multiforme in a Patient with Isolated Hemimegalencephaly
We present an exceptional case of a patient with hemimegalencephaly and secondary intractable epilepsy treated with vagus nerve stimulation (VNS) and subsequent glioblastoma development in the hemimegalencephalic hemisphere 6 years after surgery. VNS (at age 18 years) led to a 60% reduction of intractable seizures. However, symptoms of intracranial hypertension suddenly occurred 6 years after surgery. A computed tomography scan revealed a brain tumor in the hemimegalencephalic hemisphere. Pathologic examination confirmed glioblastoma multiforme. The genetic background of hemimegalencephaly is discussed here, with attention...

Case Report: Intraneural Intracanalicular Ganglion Cyst of the Hypoglossal Nerve Treated by Extradural Transcondylar Approach
We report a case of an intraneural ganglion cyst of the hypoglossal canal. The patient presented with unilateral hypoglossal nerve palsy, and magnetic resonance imaging showed a small lesion in the hypoglossal canal with no contrast enhancement and high signal on T2-weighted imaging. The lesion was assumed to be a cystic schwannoma of the hypoglossal nerve. Stereotactic irradiation was considered, but in accordance with the patient's wishes, surgical exploration was performed. This revealed that, rather than a schwannoma, the patient had an intraneural ganglion cyst, retrospectively contraindicating irradiation as an optio...

Brain Slump Caused by Jugular Venous Stenoses Treated by Stenting: A Hypothesis to Link Spontaneous Intracranial Hypotension with Idiopathic Intracranial Hypertension
We describe a patient with severe symptoms of spontaneous intracranial hypotension and brain slump documented by magnetic resonance imaging whose clinical syndrome and structural brain anomaly resolved completely after treatment directed exclusively at improving cranial venous outflow. Diagnostics included computed tomography (CT) venography, catheter venography, and jugular venoplasty. CT venography showed narrowing of both internal jugular veins below the skull base. Catheter venography confirmed that these were associated with pressure gradients. Jugular venoplasty performed on two separate occasions as a clinical test ...

Conus Medullaris Teratoma with Utilization of Fiber Tractography: Case Report
Conclusions Conus medullaris teratomas mostly affect adults. Patients generally present with a long history of clinical symptoms prior to diagnosis. Surgery is required for diagnosis, and the goal should be complete tumor excision without sacrificing any neurologic functions. The use of DTI and tractography, in addition to conventional MRI, has the potential to be very valuable for the diagnosis, surgical planning, and follow-up of patients with conus medullaris teratomas.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source:...

Spontaneous Cerebrospinal Fluid Otorrhea from a Persistent Tympanomeningeal Fissure Presenting as Recurrent Serous Otitis Media
We describe spontaneous cerebrospinal fluid (CSF) otorrhea through a patent tympanomeningeal (Hyrtl) fissure presenting as recurrent serous otitis media. The CSF leak was observed when a drain was placed through the tympanic membrane by an otologist. The diagnosis was then confirmed by computed tomography and magnetic resonance imaging, and the patient underwent a successful surgical treatment via a retrosigmoid approach. We describe the case and review causes of spontaneous CSF rhinorrhea/otorrhea.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open a...

Management of Trigeminal Neuralgia Caused by an Intraneural Spiral Trigeminocerebellar Artery: A Case Report
We report a case of trigeminal neuralgia with right vertebral artery aneurysm caused by an intraneural TCA that compressed the trigeminal nerve in multiple places. We performed proximal trapping for the fusiform aneurysm with extra-intracranial bypass to preserve flow of the posterior inferior cerebellar artery, followed by microvascular decompression that successfully changed the course of the TCA. This procedure provided relief from the neuralgia without direct bisection of the trigeminal nerve that may cause severe nerve injury. Reshaping of the course of the artery can achieve good pain relief.[...]Georg Thieme Verlag ...

Entrapment of the Temporal Horn as a Cause of Pure Wernicke Aphasia: Case Report
We report a case of a 58-year-old man who presented with pure Wernicke aphasia (never described before in the albeit rare cases of isolated temporal horn dilatation) that regressed completely following successful ventriculoperitoneal shunting. The relevant literature is also briefly reviewed.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Neurological Surgery Reports)
