OBJECT: Primary steps in the cavernous angiomas (CAs) surgery are a precise lesion identification and an optimal trajectory definition. Doing so, navigation techniques allow better results compared to microsurgery alone. In this paper we define the benefits of Intra-Operative Ultra-Sound (IOUS) use in addition to standard localization systems. METHODS: We retrospectively analyzed 59 CAs comparing two groups: 34 cases of frame-based and frameless navigation-assisted microsurgery (no-IOUS group) versus 25 cases of IOUS-guided microsurgery associated with these techniques (IOUS group)...

Cavernous hemangiomas are not true vascular tumors, but rather are slow-flow venous malformations (VMs). They are present at birth as nonproliferating vascular birthmarks composed of anomalous ectatic venous channels. VMs have often been incorrectly called cavernous hemangiomas and cavernous angiomas. These terms have for a long time lead to confusion with the more common proliferating or true hemangioma of infancy. VM has been reported to arise at all sites including skin and subcutaneous layers of the head and neck, face, extremities, liver, gastrointestinal tract, and even the thymus...

Radiotherapy is a useful modality for the treatment of brain tumors, but may induce brain degeneration, tumor formation, and vasculopathy in the irradiated field. We describe a rare case of a pediatric patient who presented multiple different types of vascular events consecutively in the irradiated field including lacunar stroke because of occlusion of perforating artery, intraventricular hemorrhage from cavernoma, and subarachnoid hemorrhage because of the rupture of fusiform aneurysm, 6 years after radiotherapy against pilocytic astrocytoma...

BACKGROUND: Brain cavernous angiomas with symptomatic hemorrhage (CASH) are uncommon but exact a heavy burden of neurological disability from recurrent bleeding, for which there is no proven therapy. Candidate drugs to stabilize the CASH lesion and prevent rebleeding will ultimately require testing of safety and efficacy in multisite clinical trials. Much progress has been made in understanding the epidemiology of CASH, and novel biomarkers have been linked to the biological mechanisms and clinical activity in lesions...

Intracranial cavernous angiomas (CAs) are hamartomatous vascular malformations consisting of thin-walled vascular channels located within the brain, but typically lacking intervening neural parenchyma, large feeding arteries, or draining veins. The CAs occurring in the ventricular system are rare, with an incidence of 2.5% to 10.3% of the intracranial CAs, and those arising from the trigone of the lateral ventricle are even rarer. Till now, there are <20 patients with trigonal CAs have been reported in the English literature...

The majority of spinal cavernous angiomas (CAs) originate from the vertebral bodies with or without epidural space extension. Solitary epidural CAs are rare. In the present study, we retrospectively reviewed the records of 12 patients who underwent microsurgery for solitary spinal epidural CAs. All patients had performed pre- and postoperative magnetic resonance imaging. The patients were 7 females and 5 males with the mean age of 52.1 years. Two tumors were located in the cervicothoracic spine, nine in the thoracic spine and one in the lumbar spine, respectively...

BACKGROUND Invasive mucinous adenocarcinoma (IMA) is a rare variant of adenocarcinoma of the lung. It frequently shows KRAS mutations, while ALK rearrangement is exceedingly rare. We present a case of ALK-rearranged IMA of the lung presenting with an unusual pattern of brain metastases, radiologically mimicking a cavernous angioma. CASE REPORT A 44-year-old non-smoker female was first diagnosed with lung right lower lobe IMA with ALK rearrangement. Five years after surgery followed by chemotherapy, she developed a sudden onset headache...

Pilocytic astrocytoma (PA), featuring activation of the mitogen-activated protein kinase (MAPK) pathway, is the most common tumor of the pediatric central nervous system. However, it remains unknown whether MAPK activation is present in the reactive gliosis of non-neoplastic lesions. Therefore, we investigated the expression of MAPK in reactive gliosis associated with cavernous angiomas. Immunohistochemical expression and the extent of BRAF, ERK, p38, and JNK were investigated in 10 patients with gliosis surrounding cavernous angiomas (GS group) and 10 patients with PA (PA group)...

BACKGROUND: Hypertrophic olivary degeneration (HOD) is a rare phenomenon in the dento-rubro-olivary pathway caused by lesion or disruption of the fibers of the Guillain-Mollaret triangle. Hemorrhage of pontine and midbrain cavernous angiomas can rarely lead to HOD portending neurologic deterioration and possible concomitant life-threatening complications; for this reason, it may define a poignant consideration in planning intervention. CASE DESCRIPTION: The patient was a 57-year-old woman with known midbrain-pontine cavernous angioma...

BACKGROUND: Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital vascular disorder characterized by the classic triad of cutaneous nevi, venous varicosities, and osseous and soft tissue hypertrophy of the affected limb. Various vascular anomalies of the central nervous system have also been described in patients with KTWS. The English language literature to date contains 6 reports of associations between KTWS and spinal cord cavernous angioma (CA), but management of these patients has not been well described...

Pilocytic astrocytoma (PA) commonly occurs during the first two decades of life. Typical locations include cerebellum, optic nerve, optic chiasm/hypothalamus and brainstem. PA should be considered in the differential diagnosis of patients with brain tumors manifesting with hemorrhagic onset. We report a case of a hemorrhagic onset of cerebellar PA in a young adult with imaging findings mimicking cavernous angioma. We also discuss imaging features and histological characteristics with a focus on the etiology of the hemorrhagic onset...

The authors' initial experience with the endoscopic extradural supraorbital approach to the temporal pole and adjacent area is reported. Fully endoscopic surgery using the extradural space via a supraorbital keyhole was performed for tumors in or around the temporal pole, including temporal pole cavernous angioma, sphenoid ridge meningioma, and cavernous sinus pituitary adenoma, mainly using 4-mm, 0° and 30° endoscopes and single-shaft instruments. After making a supraorbital keyhole, a 4-mm, 30° endoscope was advanced into the extradural space of the anterior cranial fossa during lifting of the dura mater...

Gorham-Stout disease (GSD) is a rare angiomatous disorder characterized by osteolysis. We report the case of a 66-year-old woman who developed sudden left eye proptosis and facial pain. Neuroimaging demonstrated a destructive mass involving the roof and lateral wall of the left orbit with adjacent abnormal orbital soft tissue. An initial biopsy of the soft tissue was nondiagnostic; however, transcranial biopsy of the orbital roof revealed an intraosseous cavernous angioma, with infiltration of orbital fat by angiomatous tissue...

Atopic myelitis, a type of myelitis which appears in patients with elevated serum levels of immunoglobulin E (IgE), occurs more commonly in the cervical spinal cord, but this mechanism has not yet been elucidated. Herein, we experienced a case of atopic myelitis developed during the growth of cervical cavernous angioma caused by bleeding. A 37-year-old woman suffered from hand swelling caused by a house cat licking. At the same time when cavernous angioma had grown, she experienced a numbness in her four extremities, and multifocal peritumoral hyperintense spinal cord signals were seen...

Existing literature suggests that use of telemedicine during postoperative appointments can increase access to care and is valued by patients and providers alike. While research examining the clinical equivalency of telemedicine visits for postoperative care has been growing, few studies have reported on telemedicine follow-up after neurosurgery. This study examined if a videoconferencing visit could substitute for an in-person clinic visit for elective neurosurgical cases in the USA. This was a single-center prospective study of patients who underwent elective neurosurgical procedures (aneurysm clipping, resection of cavernous angiomas, resection of arterial venous malformation, microvascular decompression for trigeminal neuralgia and hemifacial spasm, and certain benign brain tumors) and were offered telemedicine follow-up care by an allied health professional during the first 90 days after neurosurgery...
