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...

INTRODUCTION: Cerebral cavernous malformation (CCM) is a vascular disorder characterized by the presence of central nervous system cavernomas. In familial forms, mutations in three genes (CCM1/KRIT1, CCM2/MGC4607 and CCM3/PDCD10) were identified. We describe a Portuguese family harboring a novel CCM1 mutation. CASE PRESENTATION: The proband is a woman who at the age of 55 years started to have complex partial seizures and episodic headache. Although nothing was found during her neurological examination, brain MRI showed bilateral, supra- and infratentorial cavernomas...

Radiation-induced vascular "malformations", designated cavernous hemangiomas/cavernomas ("RICHs"), are seldom biopsied and are usually diagnosed based on neuroimaging features. They are an increasingly recognized complication of both CNS external beam radiation therapy and stereotactic radiosurgery. We identified 13 patients with radiation-induced vascular "malformations" in our surgical neuropathology databases searched from 2000 to 2016; 4 had received their therapy during childhood; 5 had received radiosurgery...

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...

This is a case report of de novo development of two cerebral cavernous malformations adjacent to existing developmental venous anomalies. The development of cavernomas was noted over a follow-up period of 10 years. These developments happened during the course of staged endovascular management of a complex dural arterio-venous fistula along the right sphenoid wing. The patient presented with a proptosis secondary to lympho-haemangiomatous lesion of the fronto-orbital region and a high-flow right sphenoid wing dural arterio-venous fistula...

OBJECTIVE: To report a case of a patient with multiple cerebral cavernous malformations (CCM). OBSERVATION: A 22year old man with mild von Willebrand disease presented with two occipital CCM, one of them with acute hemorrhage. Genetic testing for CCM1-3 did not reveal a mutation. Over a period of 54months, the patient suffered 26 new CCM hemorrhages despite multiple treatment attempts including thalidomide, simvastatin and hemostatic factors. Only after initiation of propranolol, which has already been successfully used in three children with giant cerebral cavernoma, the occurrence of new CCM with hemorrhages was completely stopped already at dose of 30mg daily - now for a period of 26months and without any other medications...

Neurocysticercosis (NCC) is an endemic disease and important public health problem in some areas of the World and epilepsy is the most common neurological manifestation. Multiple intracranial lesions, commonly calcified, are seen on cranial computed tomography (CT) in the chronic phase of the disease and considered one of the diagnostic criteria of the diagnosis. Magnetic resonance imaging (MRI) is the test that better depicts the different stages of the intracranial cysts but does not show clearly calcified lesions...

OBJECTIVE The aim of this paper is to define an overall cavernous malformation (CM) hemorrhage rate and risk factors for hemorrhage. METHODS The authors performed a systematic, pooled analysis via the PubMed database through October 2015 using the terms "cavernoma," "cavernous malformation," "natural history," "bleeding," and "hemorrhage." English-language studies providing annual rates and/or risk factors for CM hemorrhage were included. Data extraction, performed independently by the authors, included demographic data, hemorrhage rates, and hemorrhage risk factors...

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...

BACKGROUND: Symptomatic cavernous malformations involving the brainstem are difficult to access by conventional approaches, which often require dramatic brain retraction to gain adequate operative corridor. Here, we present a successful endoscopic endonasal transclival approach for resection of a hemorrhagic, symptomatic mesencephalic cavernous malformation. CASE DESCRIPTION: A 20-year-old woman presented with acute onset of headache, nausea, and vomiting. Computed tomography scan revealed a ventral midbrain hemorrhage...

OBJECTIVE: Propranolol-induced involution is a unique biological feature of some pediatric vascular tumors, for instance infantile hemangioma (IH), cerebral cavernoma or chorioangioma. Currently, the cellular origin of these distinct tumors is unclear. In this study, we tested the hypothesis that propranolol-responsive vascular tumors are derived from common vessel-forming CD15 + progenitor cells which occur in early gestation. The aim of this study was to identify the tumor-relevant CD15 + progenitors at the early stages of embryo-placental development...

BACKGROUND AND PURPOSE: Cerebral cavernous malformation (CCM) is characterized by multiple lumen vascular malformations in the central nervous system that can cause neurological symptoms and brain hemorrhages. About 20% of CCM patients have an inherited form of the disease with ubiquitous loss-of-function mutation in any one of 3 genes CCM1, CCM2, and CCM3. The rest of patients develop sporadic vascular lesions histologically similar to those of the inherited form and likely mediated by a biallelic acquired mutation of CCM genes in the brain vasculature...

REVIEW
Nicolae Sarbu, Teresa Pujol, Laura Oleaga
Hyperintense perilesional edema in brain masses on T1-weighted images (T1WI) is an unusual radiological finding. We report three cases showing this particular type of edema, one representing cerebral hemorrhagic cavernous malformation (CCM, cavernoma) and the other two, metastases of melanoma. The association between this sign and cavernoma was recently recognized. On the other hand, in melanotic lesions, the relationship with T1WI-hyperintense perilesional edema has not yet been described. Despite being an infrequent sign, it can considerably narrow the differential diagnosis, which gives it a high value for clinical practice...

Cerebral cavernous malformations (CCMs) are vascular malformations located within the central nervous system often resulting in cerebral hemorrhage. Pharmacological treatment is needed, since current therapy is limited to neurosurgery. Familial CCM is caused by loss-of-function mutations in any of Ccm1, Ccm2, and Ccm3 genes. CCM cavernomas are lined by endothelial cells (ECs) undergoing endothelial-to-mesenchymal transition (EndMT). This switch in phenotype is due to the activation of the transforming growth factor beta/bone morphogenetic protein (TGFβ/BMP) signaling...
