Eloquent Location

Procedures on cavernous malformations of the brainstem are challenging due to their eloquent location. This accounts especially for recurrent cavernomas as surgical scars, adhesions, and functional shift might have occurred since primary surgery. We report on a 38-year-old female patient with a large recurrent brainstem cavernoma, who underwent previous successful surgery and experienced recurrent bleeding about 2 years later. She harbored a large associated developmental venous anomaly (DVA) traversing the cavernoma through the midline of the brainstem. In order to visualize complete resection and preservation of the DVA at the same time, endoscopic-assisted resection within the brainstem after decompression in the semisitting position was performed.The video can be found here: https://youtu.be/K1p-Sx7jUpA.

Cavernous malformations are angiographically occult vascular malformations. They are often associated with a developmental venous anomaly through poorly understood mechanisms. We present an unusual case of a gradually enlarging cavernous malformation associated with a developmental venous anomaly with arteriovenous shunting, suggesting venous hypertension or reflux as a potential cause of progressive growth.

Capillary Telangiectasia

ABSTRACT OBJECTIVE AND IMPORTANCE Capillary telangiectasias, cavernous malformations, and developmental venous anomalies are all vascular malformations that occur on the capillary-venous side of the cerebral circulation. The associations of capillary telangiectasias with venous malformations, cavernous malformations with venous malformations, and capillary telangiectasias with cavernous malformations have all been described; however, the association of all three lesions in a single patient is extremely rare. CLINICAL PRESENTATION A 52 year-old Caucasian woman presented to our clinic with an extended history of confusion, distorted visual perceptions, photophobia, neck pain, swallowing problems, and poor balance. The patient's examination was remarkable for difficulty concentrating, mild rotatory nystagmus, subtle decreased sensation over the left side of the face and body, and brisk reflexes. Review of the patient's magnetic resonance imaging examination demonstrated a cavernous malformation, a capillary telangiectasia, and a developmental venous anomaly located adjacent to one another in the brainstem. INTERVENTION Given the patient's complex constellation of symptoms and relatively mild neurological findings, it was difficult to ascribe any one of them to a specific vascular malformation. Conservative management of this patient's vascular malformations was decided upon. CONCLUSION Juxtaposition of these three different vascular lesions in the brainstem of an otherwise normal individual suggests a relationship among them. Although there are several theories that link similar associations through physiological mechanisms such as venous hypertension, we propose that a developmental event disrupting local capillary-venous pattern formation is a plausible alternative.

Venous Fistula

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. During the initial period of conservative management of the dural arterio-venous fistula, he developed de novo cavernous malformations in the left mesial temporal lobe adjacent to a developmental venous anomaly in the temporal lobe, and along with this there was engorgement of deep veins related to another existing developmental venous anomaly in the brainstem. Later during the course of endovascular treatment of the dural arterio-venous fistula, a large brainstem cavernoma developed adjacent to the brainstem developmental venous anomaly. This case report discusses the cause-effect relationship of venous pressure changes related to management of dural arterio-venous fistula and de novo formation of cerebral cavernous malformations adjacent to existing developmental venous anomalies.

Abstract We describe the case of a 26-yr-old male who presented with headaches, dizziness, and left hemi-hypoesthesia in addition to being COVID-19 positive. The patient was found to have a large hemorrhage in the right dorsolateral pons that was found to be due to a pontine cavernous malformation. The patient underwent a right-sided paramedian supracerebellar infratentorial approach for resection of this lesion with preservation of the developmental venous anomaly. We present the operative video with a specific focus on approach selection, anatomic illustrations, and technical nuances. The literature on the timing of brainstem cavernoma surgery is reviewed.1-4 The patient's postoperative clinical course and postoperative imaging are reviewed. The patient gave informed consent for the procedure and verbal consent for being part of this submission and the publication of their image.

Background: Cerebral cavernous malformations (CCMs) are intracranial vascular malformations that can exist as a single lesion or mixed vascular lesions. The most common mixed form is the coexistence of CCM with an associated developmental venous anomaly (DVA). In this paper, we aim to give a comprehensive review of CCM, DVA, and their coexistence as mixed lesions. A PubMed search using the keywords “Cerebral cavernous malformations, Developmental venous anomaly, Mixed Cerebral cavernous malformations with Developmental venous anomaly” was done. All studies in the English language in the past 10 years were analyzed descriptively for this review. Summary: The search yielded 1,249 results for “Cerebral cavernous malformations,” 271 results for “Developmental venous anomaly,” and 5 results for “Mixed Cerebral cavernous malformations with Developmental venous anomaly.” DVA is the most common intracranial vascular malformation, followed by CCM. CCM can have a wide array of clinical presentations like hemorrhage, seizures, or focal neurological deficits or can also be an incidental finding on brain imaging. DVAs are benign lesions by nature; however, venous infarction can occur in a few patients due to acute thrombosis. Mixed CCM with DVA has a higher risk of hemorrhage. CCMs are angiographically occult lesion, and cerebral digital subtraction angiography is the gold standard for the diagnosis of DVA. Mixed lesions, on the other hand, are best diagnosed with magnetic resonance imaging, which has also been effective in detecting specific abnormalities. Asymptomatic lesions are treated through a conservative approach, while clinically symptomatic lesions need surgical management. Conclusion: Individual CCM or DVA lesions have a benign course; however, when they coexist in the same individual, the hemorrhagic risk is increased, which prompts for rapid diagnosis and treatment.

Developmental venous anomaly (DVA)/ Cerebral Venous Angioma is the most common type of cerebral vascular malformations, mostly an incidental benign finding. But there are documented associated complications like parenchymal signal abnormalities, thrombosis, cavernous malformations and parenchymal atrophy. In this report, we present a unique case of cerebral DVA with cortical changes mimicking the Glioma. Altered haemodynamics in DVA is the underlying pathophysiology for these changes. Correct MRI interpretation, by an expert neuroradiologist, can establish the diagnosis of DVA and its related changes. Therefore, it can reduce the morbidity and mortality by preventing the unnecessary invasive procedures like biopsy for diagnosis.

This is an unusual case report of an infant, who initially presented with a facial haemangioma and was later diagnosed to have a dural sinus malformation (DSM) involving the torcula. The DSM increased in size lateralising to the right transverse sinus at three months of age. Postnatal enlargement of the dural sinus has not been described before suggesting a delay in the maturation of the dural sinus which normally would occur antenatally. There was a further association with a complex developmental venous anomaly (DVA) draining the right cerebral hemisphere into the deep cerebral vein and multiple cavernous malformations. The DVA was not clearly demonstrated at age one month but was more obvious at age three months. This would be the first reported case of DSM associated with a DVA. Increasing venous hypertension probably contributed to the poor opacification of the DVA on follow-up angiography at age six months and to the haemorrhagic changes within the cavernomas on magnetic resonance imaging (MRI). The therapeutic goal was to correct venous hypertension by partially embolising the dural shunts to remodel the cerebral vasculature and preserve the patent sinus. The treatment strategy and possible link between the complex disease entities presented in this infant are discussed. Despite these attemps, the lesion continued to grow compressing the posterior fossa structures. The infant died at nine months of age.
