Distinguishing mimics from true hemorrhagic cavernous malformations

We report 5 cases of tumors mimicking CMs. We compared clinical, initial radiologic features, and MRI evolution between 5 tumor mimics and 51 true hemorrhagic, sporadic, brain CM. Compared to true CM, mimic patients were older (47.0 vs. 38.3 years; p = 0.076) and more likely to have a history of primary neoplasm (60% vs 12%; p = 0.0267). Radiologically, the CM mimics demonstrated a higher likelihood of lesion enhancement on the initial diagnostic MRI (60% vs. 16.7%%; p = 0.0609). On follow-up MRI (

Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Conclusions: CG-FAST scale could be an effective and simple scale for accurate identification of LVOS among AIS patients. Introduction Large vessel occlusion stroke (LVOS) often leads to severe disability and mortality. Although endovascular therapy (EVT) has been proved to be effective for LVOS patients (1–9), especially in anterior circulation, its benefit is highly time-dependent (10, 11). As hospitals with around-the-clock endovascular capability are scarce in many parts of the world and patients admitted directly to a CSC would have better outcomes than those receiving drip and ship treatment (12, 13), thi...

CONCLUSION: RCVS is difficult to diagnose given its wide array of symptoms and multifactorial etiology. In this case, RCVS plus SAH is associated with the use of anastrozole. So far there are no reported cases of aromatase inhibitors associated with this pathology and should be reported in the literature for pharmacovigilance. PMID: 30855709 [PubMed - in process]

​BY NOURA MAHDI; DARRON LEWIS; JEREMY OSBORNE; &AHMED RAZIUDDIN, MDA 73-year-old man was brought to the emergency department from his nursing home for rectal bleeding and anemia. The patient mentioned he had had episodes of bright red rectal bleeding and constipation for a few months. A colonoscopy had been done prior to the visit, which revealed a large intestine tumor and biopsy confirming adenocarcinoma. He was awaiting an appointment with his surgeon.The patient reported bloody rectal leakage, and a CBC done at the nursing home showed a hemoglobin level of 7.2. He also complained of dyspnea but denied any other s...

Abstract: Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders. Therefore, a sound understanding and thorough knowledge of poster...

AbstractThis systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic ...

Conclusions—Adult primary angiitis of the central nervous system is a heterogenous disease, with multiterritorial, distal, and bilateral acute stroke being the most common pattern of parenchymal lesions found on magnetic resonance imaging. Our findings suggest a higher than previously thought prevalence of hemorrhagic transformation and other hemorrhagic manifestations.

CONCLUSIONS: While risks of radiation exposure represent an important consideration, CT angiography and CT perfusion imaging remained the preferred imaging compared with transcranial Doppler sonography in both asymptomatic and symptomatic patients with SAH, with improved health outcomes and lower health care costs, even when modeling a significantly higher risk and shorter latency period for both cataract and brain cancer than that currently known.

We report a rare case of intraoperative tumoral bleeding of a hypervascular medulloblastoma. A 12-year-old girl presented with dizziness and nausea. Brain magnetic resonance (MR) images revealed an approximately 4.2-cm enhanced mass on the cerebellar vermis associated with mild perilesional edema and increased cerebral blood volume. Angiography showed tumoral staining and developed occipital and circular dural sinuses in the venous phase. A suboccipital craniotomy was performed. To relieve the intracranial pressure, cerebrospinal fluid (CSF) was drained via a lateral ventricular catheter in the occipital horn. During the o...
