BACKGROUND: Among the rare intraventricular cavernomas (IVCs), purely intraaqueductal cavernomas are exceptional. CASE DESCRIPTION: We report a unique case of a 62-year-old patient who presented to our clinics complaining of progressive headache, memory loss, gait instability, and urinary incontinence. MR imaging showed the presence of a mass lesion located in the lumen of the cerebral aqueduct, associated with triventricular hydrocephalus. CONCLUSIONS: We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intraaqueductal lesion, make the diagnosis of cavernoma, and treat symptoms due to hydrocephalus without increasing the risk of bleeding...

BACKGROUND: Surgeries for lesions in the dominant hippocampal and parahippocampal gyrus involving the posteromedial temporal regions are challenging to perform because they are located close to Wernicke's area; white matter fibers related with language; the optic radiations; and critical neurovascular structures. We performed a transtemporal approach with awake functional mapping for lesions affecting the dominant posteromedial temporal regions. The aim of this study was to assess the feasibility, safety, and efficacy of awake craniotomy for these lesions...

INTRODUCTION: Intraventricular cavernous angiomas are rare pathological entities, and those located at the foramen of Monro are even rarer. We herein present a case of cavernous angioma at the foramen of Monro that was successfully treated by neuroendoscope-assisted surgical removal, and review the relevant literature. CASE PRESENTATION: A 65-year-old woman had experienced headache and vomiting for 10 days before admission to another hospital. Magnetic resonance imaging (MRI) showed a mass at the foramen of Monro, and obstructive hydrocephalus of both lateral ventricles...

BACKGROUND: The resection of left-sided perisylvian brain lesions harbours the risk of postoperative language impairment. Therefore the individual patient's language distribution is investigated by intraoperative direct cortical stimulation (DCS) during awake surgery. Yet, not all patients qualify for awake surgery. Non-invasive language mapping by repetitive navigated transcranial magnetic stimulation (rTMS) has frequently shown a high correlation in comparison with the results of DCS language mapping in terms of language-negative brain regions...

Cavernous angiomas represent 5-12% of all spinal vascular lesions and 1% of all intramedullary lesions in pediatric patients. Intramedullary spinal cavernomas are relatively rare with only 24 cases reported till date to the best of our knowledge. A 15 -year-old boy presented to the clinic with acute onset motor weakness in all four limbs. He was diagnosed with multiple cerebral cavernomas and an acutely bleeding spinal cavernoma. Complete surgical excision of the spinal cavernoma was done. Postoperatively the patient's weakness gradually improved to a power of 4/5 in all his limbs over a period of 10 days...

BACKGROUND: Suprasellar cavernous malformation in the optic pathway is not commonly encountered. To date, there are only few reports present in the literature. CASE DESCRIPTION: The authors report a rare case of suprasellar optic pathway cavernous malformation in a 33-year-old female who presented with progressive visual loss. Her imaging revealed a large heterogeneous, hyperintense, hemorrhagic right suprasellar extra-axial complex cystic structure, causing mass effect on the adjacent hypothalamus and third ventricle displacing these structures...

Cavernous angiomas of the spinal cord exhibit imaging characteristics that may overlap with those of hemorrhagic ependymoma. In the present study, we aimed to identify specific magnetic resonance imaging (MRI) findings that could be used to differentiate cavernous angioma from hemorrhagic ependymoma, and to evaluate serial MRI changes in cases of cavernous angioma. We retrospectively evaluated MR images of spinal cord tumors collected at our hospital from 2007 to 2015. From this cohort of images, 11 pathologically confirmed cavernous angiomas and 14 pathologically confirmed hemorrhagic ependymomas were compared with respect to the size of the tumor, longitudinal location, axial location, enhancement pattern, syrinx, edema, tumor margin, signal intensity of T2WI, signal intensity of T1WI, and longitudinal spreading of the hemorrhage...

BACKGROUND: Understanding of cortico-cortical activity in eloquent areas intraoperatively is crucial for neurosurgical procedures. Here, we used intraoperative near-infrared spectroscopy (iNIRS) during direct cortical stimulation as a robust tool to better understand the cortico-cortical connectivity in language systems. METHODS: We applied iNIRS to 3 patients who underwent epilepsy surgery due to lesions (cavernous angioma, epidermoid cyst, and low-grade glioma) located in language areas...

Cavernous angiomas although relatively common lesions rarely reach a large size. They have a well documented association with AVMs, capillary telangiectases and venous angiomas but are not specifically associated with intracerebral aneurysms. We present a case of what we believe to be the 4th largest reported giant cavernous angioma to present in adulthood. This cavernous angioma also happened to be associated with a large intracerebral aneurysm, an association not previously reported. The sometimes confusing nomenclature of cavernous angiomas and other similar vascular malformations is also discussed...

BACKGROUND: The clinical criteria for cluster headache (CH) are included in Chapter 3 of the International Classification of Headache Disorders, 3rd beta edition (ICHD-III). CH may sometimes be secondary to other pathologies. CASE REPORTS: We report two patients in whom the clinical features of CH initially fulfilled the ICHD-III criteria, but who later presented some radical modifications in headache natural history as a result of a secondary pathology. The first case of CH was secondary to a pontine cavernous angioma and the second to a cerebral venous thrombosis...

Cavernous angiomas usually occur in the parenchyma of both the supra and infratentorial compartments. At times, they can both clinically and radiologically mimic other dural-based lesions. We present a case of a patient with chronic occipital headaches, initially thought to have a meningioma, but proven to be a cavernoma with histological analysis.

BACKGROUND: The co-occurrence of cerebral gliomas and cavernous angiomas is rarely encountered in clinical practice. All reported cases with such association have occurred within the brain with none involving the spinal cord. CASE DESCRIPTION: The authors report the case of a hypothalamic-optochiasmatic pilocytic astrocytoma coexisting with right occipital and sacral spinal cavernomas. This 30-year-old man had an 8-year history of chronic lower back pain. Spinal magnetic resonance imaging (MRI) demonstrated an 8...

Cavernous angiomas or cavernomas have been occasionally described in patients presenting with medically intractable epilepsy. Reports of cavernomas associated with a second pathology potentially causative of seizures have rarely been documented; most commonly, the second pathology is focal cortical dysplasia or less frequently, hippocampal sclerosis. To our knowledge, cases of arteriovenous malformation arising in this clinical setting and associated with hippocampal sclerosis have not been previously described...

Cavernous angiomas originating in the internal auditory canal are very rare. In the available literature, only 65 cases of cavernomas in this location have been previously reported. We describe the case of a 22-year-old woman surgically treated for a cavernous hemangioma in the left internal auditory canal, mimicking on preoperative magnetic resonance imaging MRI an acoustic neuroma. Neurological symptoms were hypoacusia and dizziness. The cavernous angioma encased the seventh and, partially, the eighth cranial nerve complex...

A 59-year-old woman presented with right sensory loss and right hemiparesis. In February 2013, she was admitted to Araki Neurosurgical Hospital. A magnetic resonance imaging was performed that revealed a left temporal lobe hemorrhage. The image also showed a chronic stereotype hematoma. After 14 days of hospitalization, she underwent a stereotactic craniotomy. Subsequently, by postoperative pathological evaluation, the hematoma was diagnosed as a cavernous angioma. She had no postoperative complications. She was provided rehabilitation support and was discharged 28 days after the admission following which she rejoined work...

Chorea is a type of hyperkinetic movement, referring to involuntary, irregular, aimless, nonrhythmic, abrupt, rapid, unsustained movements. The term hemichorea refers to chorea ofone side of the body. A 39-year-old woman presented with a three-week history of abrupt, involuntary movements of her right hand and right foot, which was compatible with hemichorea ofthe right side. MRI brain showed a 1.7 x 1.5 x 1.3 cm lesion in the posterior limb of the left internal capsule and the lateral part of the left thalamoganglionic region, which was seen as mixed iso- and hyperintense in T1W images, and heterogeneous and hyperintense in T2W/FLAIR images...
