Secondary bilateral synchrony due to fronto-mesial lesions: an invasive recording study

Frontal lobe epilepsies may present difficulties in focus localization in the pre-operative work-up for epilepsy surgery. This is specially true in patients with normal MRIs. We report on a 16 years-old girl that started with seizures by the age of 8 years. They were brief nocturnal episodes with automatisms such as bicycling and boxing. Seizure frequency ranged from 4-10 per night. Scalp EEG showed few right frontal convexity spiking and intense secondary bilateral syncrhony (SBS). High resolution MRI directed to the frontal lobes was normal. Ictal SPECT suggested a right fronto-lateral focus. Ictal video-EEG showed no focal onset. She was submitted to invasive recordings after subdural plates implantation. Electrodes covered all the frontal convexity and mesial surface bilaterally. Ictal recordings disclosed stereotyped seizures starting from the right mesial frontal. Using a high-resolution tool to measure intra and interhemispheric latencies, the timing and direction of seizure spread from the right fronto-mesial region were studied. Motor strip mapping was performed by means of electrical stimulation. She was submitted to a right frontal lobe resection, 1.5 cm ahead of the motor strip and has been seizure free since surgery (8 months). Pathological examination found a 4 mm area of cortical dysplasia. Invasive studies are needed to allow adequate localization in patients with non-localizatory non-invasive work-up and may lead to excellent results in relation to seizures after surgery.

The Brain

Background: The frontal lobes make up two-thirds of the human brain, and their functions have long remained unclear. Aim of the work: measuring cortical thickness and volume in various parts of the frontal lobe in athletic football players and non-athletes, as well as age-related changes in both sexes, using high-resolution MRI. Subjects and methods: A 40 volunteers were divided into two groups: non-football players (20 each, 10 males and 10 females) and 60 non-athletes of various ages (10-20, 20-30, and 30-40) (10 participants from each gender for each group). Results: The height, weight and BMI are increased in sport male and female groups, The medial orbitofrontal, the pars orbitalis, the superior frontal and the frontal pole in the right frontal lobe in females in the sport group, the pars orbicularis and pars triangularis in the left frontal lobe is increased significantly in the sport group, The medial orbitofrontal and pars triangularis are increased significantly in the left frontal lobe in the male group aged 10-20 years, The caudal middle frontal, the medial orbitofrontal, the paracentral, the pars triangularis, the pars orbicularis and superior frontal gyrus are increased significantly in the female aged 10-20 years in the right frontal lobe while the lateral orbitofrontal and the frontal pole increased significantly in the female aged 20-30 years and medial orbitofrontal and paracentral in female aged 10-20 years in the left frontal lobe. Conclusion: age, gender and physical exercise can affect different parameters of the frontal lobe of the brain KEY WORDS: volumetric, frontal lobe, exercise, High-resolution MRI.

Anterior communicating artery (AComA) aneurysm accompanied by visual symptoms is rarely reported. The first case is an asymptomatic 65-year-old woman who presented with an AComA aneurysm, and the pre-procedure high-resolution magnetic resonance imaging (MRI) revealed an AComA aneurysm compressed the left optic nerve and the chiasma with a size of 8.3 × 9.2 mm. She suffered a sudden onset of left eye visual loss and the temporal hemianopia of the right eye after endovascular embolization. She had a light sensation of the left eye and minor enlargement of the visual field in the right eye at the six-month follow-up. The second case is a symptomatic 55-year-old woman suffering a visual loss in the left eye and inferior nasal quadrantanopsia in her right eye. Pre-operative high-resolution MRI found an AComA aneurysm compressing the left part of the chiasma with a size of 7.1 × 8.3 mm. Her visual symptoms improved after surgical clipping. High-resolution MRI could depict the anatomic relationship between the AComA aneurysm and the surrounding optic pathways. Endovascular treatment of an AComA aneurysm may result in visual deterioration due to the mass effect or ischemia after the procedure. Surgical clipping of the AComA aneurysm could relieve the compression symptoms.

Subarachnoid Hemorrhages

Abstract Background Isolated posterior inferior cerebellar artery dissections can cause subarachnoid hemorrhages or infarctions. Surgical and endovascular treatments for hemorrhagic stroke cases and medical treatments using antithrombotic agents for ischemic stroke cases have been performed, but there are very few reports on nonstroke isolated posterior inferior cerebellar artery dissections, and the treatment strategy for nonstroke cases has not been established. This is the first detailed report on a spontaneously healed, isolated posterior inferior cerebellar artery dissection without stroke, followed by high-resolution MRI examinations. Case presentation A 48-year-old healthy male felt a severe, throbbing headache on the right side and came to our clinic on the fourth day following onset. MRI examinations revealed a right posterior inferior cerebellar artery dissection and showed no infarctions or hemorrhages. He was observed carefully with continuous monitoring of blood pressure, hydrated sufficiently, and given analgesic anti-inflammatory agents. Two weeks later, the dissected vessel’s diameter grew to the maximum size, though the patient’s headache rapidly improved around that day. Surgical or endovascular treatments for prevention of subarachnoid hemorrhage were recommended, but careful conservative therapy was continued in accordance with the patient’s wishes. Gradually, the dissection finding improved. Four months later, MRI examinations showed his right posterior inferior cerebellar artery was almost normal in size and shape. Conclusions This is the first detailed report on a nonstroke isolated posterior inferior cerebellar artery dissection that spontaneously occurred and healed, observed by serial high-resolution MRI examinations.
