Glioblastomas are highly malignant and invasive brain tumors. Cerebral cavernous malformations (CCMs) are vascular diseases of congenital and occult vascular dysplasia, which may arise sporadically or may be inherited due to autosomal dominant condition. To the best of our knowledge, cases of glioblastoma in the cerebral hemisphere mimicking cavernous malformation have not been reported in the literature. We reported a case of glioblastoma mimicking CCM. The patient was admitted at our hospital in July 2015 due to a 9-day history of intermittent dizziness. The present study reports a case of a glioblastoma on the right temporal lobe mimicking CCM, which was confirmed by postoperative pathology. The diagnosis of glioblastoma was not determined even during surgery, and the lesion was totally resected with no complications. During the surgical procedure, the lesion was very similar to a CCM. In conclusion, it is difficult to distinguish between glioblastoma and CCM. Therefore, when a lesion is present with hemorrhage and the imaging features are very similar to a vascular disease, a tumor must be considered in the differential diagnosis.

Cerebral cavernous malformations (CCM) are vascular malformations of the central nervous system (CNS) that lead to cerebral hemorrhages. Familial CCM occurs as an autosomal dominant condition caused by loss-of-function mutations in one of the three CCM genes. Constitutive or tissue-specific ablation of any of the Ccm genes in mice previously established the crucial role of Ccm gene expression in endothelial cells for proper angiogenesis. However, embryonic lethality precluded the development of relevant CCM mouse models. Here, we show that endothelial-specific Ccm2 deletion at postnatal day 1 (P1) in mice results in vascular lesions mimicking human CCM lesions. Consistent with CCM1/3 involvement in the same human disease, deletion of Ccm1/3 at P1 in mice results in similar CCM lesions. The lesions are located in the cerebellum and the retina, two organs undergoing intense postnatal angiogenesis. Despite a pan-endothelial Ccm2 deletion, CCM lesions are restricted to the venous bed. Notably, the consequences of Ccm2 loss depend on the developmental timing of Ccm2 ablation. This work provides a highly penetrant and relevant CCM mouse model.

We present the case of a 64-year old female, with a 5 year history of symptomatic multiple cerebral cavernomas, who developed paresthesia in the right leg and arm, followed by vertigo, slurred speech and forward gaze diplopia. Brain investigation revealed two lesions with supra- and infratentorial localization with signs of recent hemorrhage of different ages. The localization of the lesions in the midpons and the basal ganglia imposed a conservative approach.

Chronic encapsulated intraventricular hematoma (CEIVH) is a rare, intraventricular, nonneoplastic mass lesion that can become symptomatic from mass effect or obstructive hydrocephalus. Only 5 cases have been reported in the literature, and only one of these occurred in a pediatric patient and dates back to the pre–modern neuroimaging and pre-microsurgical era of neurosurgery. Imaging features can mimic those of many more common intraventricular lesions, such as choroid plexus tumors or cavernous malformations. In all reported symptomatic cases, resection was safely performed and led to a cure and symptom resolution. Here, the authors present a case of CEIVH in a pediatric patient, describe the operative techniques of resection, review the available literature, and discuss current understanding of the pathophysiology, making this the most comprehensive report on this disease entity to date. The case is a 14-year-old boy who presented with headaches and emesis. Computed tomography showed a hyperdense mass in the trigone of the right lateral ventricle. Magnetic resonance imaging showed a contrast-enhancing well-circumscribed mass. Right temporal craniotomy utilizing a posterior middle temporal gyrus transcortical approach was performed, and gross-total resection was achieved. Pathology revealed a CEIVH. The boy’s postoperative course was uncomplicated, and he was discharged 2 days after surgery.

We present a 25-year-old female with a history of multiple intracranial cavernous malformations complaining of vertigo. Imaging is significant for increasing size of a lesion in her left cerebellar peduncle. Given the proximity to the lateral border of the cerebellar peduncle, a retrosigmoid approach was chosen. After performing a craniotomy that exposed the transverse-sigmoid sinus junction, the dura was open and reflected. The arachnoid was sharply opened and cerebrospinal fluid was aspirated to allow the cerebellum to fall away from the petrous bone. The cerebellopontine fissure was then opened to visualize the lateral wall of the cerebellar peduncle. The cavernous malformation was entered and resected.The video can be found here: http://youtu.be/P7mpVbaCiJE.

Cowden’s disease is a rare autosomal dominant condition with characteristic mucocutaneous papillomatous lesions. These lesions are mucocutaneous markers for increased risk of malignancies in the thyroid, breast and the gastrointestinal tract. We discuss the case of a 50-year-old female patient who presented with oral and cutaneous papillomoas and a past history of breast malignancy. Important management aspects of these patients are considered.

Cavernous malformations (CMs) are found throughout the CNS but are relatively uncommon in the spine. In this report, the authors describe a giant CM with the imaging appearance of an aggressive, invasive, expansive tumor in the cervical spine. The intradural extramedullary portion of the tumor originated from a cervical nerve root; histologically, the lesion was identified as an intraneural CM. Most of the tumor extended into the paraspinal tissues. The tumor was also epidural, intraosseous, and osteolytic and had completely encased cervical nerve roots, peripheral nerves, branches of the brachial plexus, and the vertebral artery on the right side. It became symptomatic during the puerperal period. Gross-total resection was achieved using staged operative procedures, complex dural reconstruction, spinal fixation, and fusion. Clinical, radiographic, and histological details, as well as a discussion of the relevant literature, are provided.

Density Flow

Three genes, CCM1, CCM2, and CCM3, interact genetically and biochemically and are mutated in cerebral cavernous malformations (CCM). A recently described member of this CCM family of proteins, CCM2-like (CCM2L), has high homology to CCM2. Here we show that its relative expression in different tissues differs from that of CCM2 and, unlike CCM2, the expression of CCM2L in endothelial cells is regulated by density, flow, and statins. In vitro, both CCM2L and CCM2 bind MEKK3 in a complex with CCM1. Both CCM2L and CCM2 interfere with MEKK3 activation and its ability to phosphorylate MEK5, a downstream target. The in vivo relevance of this regulation was investigated in zebrafish. A knockdown of ccm2l and ccm2 in zebrafish leads to a more severe “big heart” and circulation defects compared with loss of function of ccm2 alone, and also leads to substantial body axis abnormalities. Silencing of mekk3 rescues the big heart and body axis phenotype, suggesting cross-talk between the CCM proteins and MEKK3 in vivo. In endothelial cells, CCM2 deletion leads to activation of ERK5 and a transcriptional program that are downstream of MEKK3. These findings suggest that CCM2L and CCM2 cooperate to regulate the activity of MEKK3.

Cavernous Hemangiomas

✓Cavernous hemangiomas that occur within the cavernous sinus (CS) are different from cerebral cavernous malformations (CMs) clinically, on imaging studies, and in their response to treatment. Moreover, CMs are true vascular malformations, whereas hemangiomas are benign vascular tumors. Because of these differences, the authors suggest that these two entities be analyzed and grouped separately. Unfortunately, despite these differences, much confusion exists in the literature as to the nature, behavior, and classification of these two distinct lesions. This confusion is exacerbated by subtle histological differences and the inconsistent use of nomenclature. The authors use the term “cavernous malformation” to refer to intraaxial lesions only; they prefer to use the term “cavernous sinus hemangioma” to refer to extraaxial, intradural hemangiomas of the CS.

A two-year-ten-month-old entire female fancy rat was evaluated for acute-onset neurological signs following a two-month history of lethargy and behavioural changes. Physical examination revealed generalised muscle atrophy. Neurological examination localised the lesion likely to the right thalamus based on suspected left unilateral hemineglect. The patient was euthanased over quality-of-life concerns, and postmortem MRI of the brain was performed, followed by postmortem examination. This showed a lesion in the region of the pituitary which was T1 hyperintense to the brain, T2 isointense to the white matter and hypointense on gradient echo sequences, suggesting subacute haemorrhage. The authors described the clinical presentation and imaging features (MRI) of suspected pituitary apoplexia secondary to a pituitary macroadenoma in an aged female rat. Of particular interest are the findings of unilateral hemineglect and blooming artefact on MRI gradient echo sequences that lead to suspicion of pituitary apoplexia confirmed on postmortem examination.
