Background: Tentorial dural arteriovenous fistula (TDAVF) is a rare intracranial vascular shunt. A TDAVF can be supplied by the Artery of Wollschlaeger and Wollschlaeger (AWW). However, a limited number of cases of TDAVF fed by the AWW have been reported to date. Case Description: A 70-year-old woman complaining of the right motor weakness underwent magnetic resonance imaging. A vascular lesion beneath the cerebellar tentorium was incidentally found with chronic infarction of the left corona radiata. Angiographically, the vascular lesion was a TDAVF supplied by the bilateral posterior meningeal arteries. No other apparent feeders were detected. The TDAVF had a shunting point on the inferior surface of the cerebellar tentorium with venous retrograde flow (Borden type III, Cognard type III). To prevent vascular events, endovascular embolization was performed using n-butyl-2-cyanoacrylate. Following embolization of the shunting point, a residual shunt fed by the AWW was identified. The shunt supplied by the AWW was not observed preoperatively. Follow-up angiography performed 1 week later revealed spontaneous disappearance of the residual shunt. The patient was followed-up in our outpatient clinic, and no recurrence of the TDAVF was confirmed postoperatively. Conclusion: Detection of mild feeding from the AWW to a TDAVF can be elusive preoperatively. Following embolization of the main shunting point, residual shunting from the AWW can resolve spontaneously.

Abstract Background Functional connectivity (FC) has been used to investigate the pathophysiology of migraine. Accumulating evidence is pointing toward malfunctioning of brainstem structures, i.e., the red nucleus (RN) and substantia nigra (SN), as an important factor in migraine without aura (MwoA). We aimed to identify atypical FC between the RN and SN and other brain areas in patients with MwoA and to explore the association between RN and SN connectivity changes and performance on neuropsychological tests in these patients. Methods Resting-state functional magnetic resonance imaging (fMRI) data were obtained from 30 patients with MwoA and 22 age-, sex-, and years of education-matched healthy controls (HC). The FC of the brainstem structures was analyzed using a standard seed-based whole-brain correlation method. The results of the brainstem structure FC were assessed for correlations with other clinical features. Results Patients with MwoA exhibited reduced left RN-based FC with the left middle frontal gyrus, reduced right RN-based FC with the ipsilateral superior parietal lobe, and increased FC with the ipsilateral cerebellum. Additionally, patients with MwoA demonstrated significantly decreased right SN-based FC with the right postcentral gyrus, left parietal lobule, and left superior frontal gyrus. Hypo-connectivity between the right SN and right postcentral gyrus was negatively correlated with disease duration (r = − 0.506, P = 0.004). Additionally, increased connectivity of the right RN to the ipsilateral cerebellar lobes was positively correlated with the Headache Impact Test-6 scores (r = 0.437, P = 0.016). Conclusions The present study suggested that patients with MwoA have disruption in their RN and SN resting-state networks, which are associated with specific clinical characteristics. The changes focus on the regions associated with cognitive evaluation, multisensory integration, and modulation of perception and pain, which may be associated with migraine production, feedback, and development. Taken together, these results may improve our understanding of the neuropathological mechanism of migraine.

AbstractWyburn–Mason syndrome is a rare condition that is characterized by ipsilateral arteriovenous malformations affecting the eye, brain, and facial skin. A conjunctival vascular dilation can be a rare ocular presenting sign. We report a 6-year-old boy who attended the hospital because of the sudden appearance of a conjunctival vascular lesion in his right eye. Inspection of his facial skin showed a subtle discoloration along the right trigeminal nerve and a vascular structure of the conjunctiva. Fundoscopy showed dilated and tortuous retinal vessels. Brain magnetic resonance imaging (MRI) revealed a large arteriovenous malformation involving the thalamus and perimesencephalic area. Ophthalmologic and neuroradiologic findings were consistent with the diagnosis of Wyburn–Mason syndrome. The sudden emergence of a vascular malformation in the conjunctiva should alert the clinician to perform an ophthalmoscopy, and in our patient, this finding was the clue to diagnosis of Wyburn–Mason syndrome. Because of the association between retinal and intracranial arteriovenous malformations, an MRI of the brain is strongly recommended in all patients with ocular arteriovenous malformations.

✓ This 10-year-old child suffered a hemorrhage into the right parietal lobe, the result of a ruptured arteriovenous angioma. From birth, the boy had a venous angioma of the mucous membrane of the cheek, lower lip, and hypoglossal area on the right side. The coexistence of these two vascular defects is most unusual, and venous angioma in early life may suggest the presence of cerebral angioma.

Transtentorial Approach

A 57-year-old man presented with acute changes in mental status. Brain CT showed a high-density lesion at the pons. Brain MRA revealed a very slow-flow vascular lesion at the right aspect of the pons, about 3.9 ⋅ 3.0 ⋅ 3.0 cm3, compatible with a pontine cavernous malformation (CM). Gross-total removal was achieved. In this approach, a wider surgical corridor was obtained by opening the Meckel’s cave and cutting the tentorium. For a midline attack point on the pons, additional removal of the posterior clinoid process can meet the goal. In the authors’ opinion, this approach is safe and effective in selected ventrolateral pontine CMs.The video can be found here: https://youtu.be/moHqEkp5eCA.

Abstract A 70-year-old gentleman was referred to our department for atypical chest pains and night sweats. He had an unremarkable past medical history and denied any history of familial disease. There were no complaints of dyspnoea, dizziness or palpitations. A routine echocardiogram showed a suspicious right atrial mass, seemingly extra cardiac in origin. Clinical examination was entirely unremarkable and further investigations were arranged as a matter of urgency. Contrast echocardiography confirmed a lesion wrapping around the right atrium with possible myocardial infiltration. Trans-oesophageal echocardiography showed extension of the mass into the adjacent atrioventricular groove. The appearances were of a compressive, non-vascular lesion measuring 4.8cm x 5.6cm. Overall cardiac systolic function remained preserved with no significant intra-cardiac abnormalities. A CT Thorax with contrast was the next step in investigation. This demonstrated nodular soft tissue infiltration of the entire pericardium, mainly involving the right heart chambers with encasement of the aortic root and coronary arteries. Significant lymphadenopathy was also identified suggesting a malignant process. Cardiac MRI was then performed and this substantiated the findings on CT, raising concern for encasement and external compression of the right coronary artery. Urgent transfer to a tertiary cardiac centre was arranged and subsequent biopsy confirmed histological diagnosis of Stage 4 Lymphoma. After a multi-disciplinary meeting, a non-operative approach was decided. Treatment with steroids and chemotherapy was commenced without delay leading to a significant reduction in the size of the mass. Abstract P1325 Figure.

Meningeal Artery

This 52-year-old man with no remarkable medical history, no anticoagulation use, and no history of trauma was noted to have a subacute–chronic left subdural hematoma during outpatient headache evaluation. No occult vascular lesion or cross-calvarial supply of the right middle meningeal artery (MMA) to the left side was identified on bilateral selective external carotid injections. Because the patient preferred non-surgical management, we performed a left MMA embolization with Onyx 18 (Medtronic), utilizing a Headway Duo microcatheter (MicroVention) via the transradial route. A 6 French Benchmark (Penumbra) was utilized for transradial support into the left external carotid. The patient was discharged home the same day. Repeat scans from 2 to 6 weeks revealed complete resolution of the subdural hematoma. The patient’s headaches resolved. Transradial MMA embolization for subacute–chronic subdural hematoma represents a minimally invasive treatment option for mass effect and hemorrhage-related symptoms. Tailored embolizations are necessary when >1 meningeal vessel supplies the subdural hematoma.

Background: We describe a rare case of idiopathic lower cervical vertebro-vertebral arteriovenous fistula (VVAVF) with compression of the nerve roots and spinal cord, successfully treated with detachable coils utilizing the transarterial balloon-assisted technique without complication of coil mass. Case Description: A 68-year-old woman was admitted for numbness of the left upper limb and pain in the left neck. Cervical magnetic resonance imaging (MRI) revealed compression of nerve roots and spinal cord by a large vascular lesion. The left vertebral angiography demonstrated a VVAVF draining into the vertebral venous plexus at C5 level. Under general anesthesia, the fistula site was accessed with a microcatheter through the right femoral artery, and successful embolization performed by compactly placing several detachable coils using balloon-assisted technique. The patient made a full recovery, with long-term MRI-documented left vertebral artery patency and no fistular leakage, and without postoperative complications. Conclusion: Target occlusion utilizing the balloon-assisted technique in this case of VVAVF with compression of nerve roots and spinal cord, was effective in improving neurological symptoms, and achieved long-term occlusion when preservation of the VA was desired.

Masson’s tumor is a rare, benign, vascular lesion, commonly affecting the head, neck and peripheries. It is usually asymptomatic and can be confused with malignant tumors. We report a 56-year-old male who presented with a solitary swelling in the right side of neck which was clinically diagnosed as a benign cystic lesion, hence complete excision of the lesion was done. Histopathology demonstrated the papillary proliferation of endothelial cells, in favour of Masson’s tumor.

High Index Of Suspicion

Background: Brain arteriovenous malformations (AVMs) are congenital aberrant connections between afferent arteries and draining veins with no intervening capillary bed or neural parenchyma. Other than seizures, the most common initial presentation of AVM is hemorrhage, which is typically intraparenchymal, subarachnoid, or intraventricular, and very rarely subdural. Case Description: This patient is a 66-year-old male with a history of atrial fibrillation, chronically anticoagulated with apixaban, who presented through emergency services after a fall. On presentation, computed tomography (CT) of the head showed a small, 6 mm right subdural hematoma, and the patient was neurologically intact. The hematoma was evacuated by burr hole craniotomy and placement of a subdural drain 12 days after the initial presentation due to worsening headaches and further hematoma expansion. Two weeks postevacuation, the patient was readmitted for seizures, and at this time, CT angiography showed no intracranial vascular lesion. Approximately 1 month later, the patient was readmitted for decreased responsiveness, and CT head at this time found right frontal intraparenchymal hemorrhage. On subsequent catheter angiography, the right frontal AVM was discovered. It was treated with preoperative embolization followed by surgical resection. Postoperatively, the patient followed commands and tracked with his eyes. There was spontaneous antigravity movement of the right upper extremity, but still no movement of the left upper or bilateral lower extremities. Conclusion: This case emphasizes the importance of maintaining a high index of suspicion for underlying vascular lesions when evaluating intracranial bleeding, even in the setting of traumatic history, particularly in cases of hematoma expansion.
