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.

We describe a right-handed patient who suffered a ruptured aneurysm of the anterior communicating artery (ACoA) which was clipped successfully. Computerized tomography indicated a low density area in the genu of the corpus callosum and the infero-lateral aspect of the left frontal lobe. On recovery the patient's most notable deficit was the “alien hand sign” whereby the left hand would frequently interfere with the actions of the right hand. Problems in response initiation were also evident. There was significant memory loss and performance was impaired on some tests of frontal lobe function. Discussion centres on the functional locus of the alien hand sign but other aspects of the patient's deficits are also considered.

Objective The aim of the present work was to observe the activation/deactivation of cerebral functional regions after electroacupuncture (EA) at Yintang (EX-HN3) and GV20 by functional MRI (fMRI). Design A total of 12 healthy volunteers were stimulated by EA at Yintang and GV20 for 30 min. Resting-state fMRI scans were performed before EA, and at 5 and 15 min after needle removal. Statistical parametric mapping was used to preprocess initial data, and regional homogeneity (ReHo) and amplitude of low-frequency fluctuation (ALFF) were analysed. Results ReHo at 5 min post stimulation showed increases in the left temporal lobe and cerebellum and decreases in the left parietal lobe, occipital lobe and right precuneus. At 15 min post stimulation, ReHo showed increases in the left fusiform gyrus; lingual gyrus; middle temporal gyrus; postcentral gyrus; limbic lobe; cingulate gyrus; paracentral lobule; cerebellum, posterior lobe, declive; right cuneus and cerebellum, anterior lobe, culmen. It also showed decreases in the left frontal lobe, parietal lobe, right temporal lobe, frontal lobe, parietal lobe and right cingulate gyrus. ALFF at 5 min post stimulation showed increases in the right temporal lobe, but decreases in the right limbic lobe and posterior cingulate gyrus. At 15 min post stimulation ALFF showed increases in the left frontal lobe, parietal lobe, occipital lobe, right temporal lobe, parietal lobe, occipital lobe and cerebellum, but decreases in the left frontal lobe, anterior cingulate gyrus, right frontal lobe and posterior cingulate gyrus. Conclusions After EA stimulation at Yintang and GV20, which are associated with psychiatric disorder treatments, changes were localised in the frontal lobe, cingulate gyrus and cerebellum. Changes were higher in number and intensity at 15 min than at 5 min after needle removal, demonstrating lasting and strong after-effects of EA on cerebral functional regions.

Hyper immunoglobulin-E (IgE) syndrome is an autosomal immune deficiency disease. It is characterized by an increase in IgE and eosinophil count with both T-cell and B-cell malfunction. Here, we report an 8-year-old boy whose disease started with an unusual skin manifestation. When 6 months old he developed generalized red, nontender nodules and pathologic report of the skin lesion was unremarkable (inflammatory). Then he developed a painless, cold abscess. At the age of 4 years, he developed a seronegative polyarticular arthritis. Another skin biopsy was taken which was in favor of Keratoacanthoma. Laboratory workup for immune deficiency showed high eosinophil count and high level of immunoglobulin-E, due to some diagnostic criteria (NIH sores: 41 in 9-year-olds), he was suggestive of hyper IgE syndrome. At the age of 8, the patient developed an abscess in the left inguinal region. While in hospital, the patient developed generalized tonic colonic convulsion and fever. Brain computed tomography scan revealed an abscess in the right frontal lobe. Subsequently magnetic resonance imaging (MRI) of the brain indicated expansion of the existing abscess to contralateral frontal lobe (left side). After evacuating the abscesses and administrating intravenous antibiotic, the patient’s condition improved dramatically and fever stopped.

The study of patients undergoing unilateral frontal-lobe excisions for the relief of focal epilepsy has revealed specific cognitive disorders that appear against a background of normal functioning on many intellectual, perceptual and memory tasks. Lesions that invade the frontal eye field cause subtle impairments of voluntary oculomotor control, which reveal themselves as an inability to suppress an initial glance at a potentially distracting stimulus. After frontal lobectomy in either hemisphere, deficits are found quite consistently on motor-differentiation tasks (Konorski 1972) in which the subject must learn to produce different responses to different, randomly presented, environmental signals. More directly related to the concept of planning are those sequential tasks in which the subject is free to choose his own order of responding, but must not make the same response twice. Here the left frontal lobe plays the major role, a finding consistent with the notion of left-hemisphere dominance for the programming of voluntary actions. In contrast, the right frontal lobe appears to be more critically involved in monitoring the temporal sequence of externally ordered events, although the verbal or non-verbal nature of the stimuli remains a relevant factor.

Winnicott and O’Flynn present the case of a six-year-old at death, who had been under observation at the Queen’s Hospital for Children for several years. Besides the odd complaints from which she suffered, it was always felt that some more important disease might be present. The child always did well in hospital and at the convalescent home. Later, acute symptoms pointed directly to intracranial disease, and tuberculous meningitis was expected. A postmortem report revealed a large abscess in the right frontal lobe of the brain, involving the whole anterior half of the right hemisphere, and extremely congested kidneys.

abstract BACKGROUND AND IMPORTANCE: Arachnoid cysts have not been reported to be located within the brain parenchyma. We present a case of an arachnoid cyst that was contained entirely within the right frontal lobe devoid of communication with the subarachnoid space and ventricle. CLINICAL PRESENTATION: A 65-year-old woman presented with a 1-year history of progressive headache and nausea. Computed tomographic and magnetic resonance imagining scans showed a well-defined, nonenhancing mass measuring 5 × 5 × 3.5 cm in the right frontal lobe. The mass appeared to be contained entirely within the brain parenchyma. The patient underwent a right frontal craniotomy, at which time the cystic mass was identified in the brain parenchyma without any communication with the arachnoid space. The cyst contained a clear fluid, and its wall was excised. The fluid contents demonstrated a composition similar to that of normal cerebrospinal fluid. Histological and immunohistochemical examinations of the cyst wall were compatible with the diagnosis of an arachnoid cyst. Postoperatively, the symptoms of the patient resolved, and no recurrence was observed up to 6 months after removal. CONCLUSION: The present case showed an intraparenchymal arachnoid cyst arising in the frontal lobe. Although the etiology is not known, an arachnoid cyst should be included in the differential diagnosis of primary intracerebral cysts.

A 51-year-old woman had been diagnosed and treated for schizophrenia for 10 years. Two weeks prior to admission, she developed headache and diplopia. Then, she was found unconscious and was sent to the hospital. A tumour in the left frontal lobe of the brain, causing brain herniation, was diagnosed and surgical excision of tumour was performed immediately. The psychotic symptoms of the patient were completely resolved after surgery. The histological diagnosis was meningioma. This case demonstrates an uncommon presentation of meningioma, the most common primary brain tumour. Patients presenting with psychotic symptoms may be misdiagnosed with schizophrenia, when a tumour is present, allowing the tumour to grow and causing associated complications. Early diagnosis and treatment could prevent mortality and morbidity. The treating physician should be aware of organic possibilities and carefully search for atypical presentations of psychiatric disorders in their patients.

Term Monitoring

Intracranial pressure (ICP) measurements are imperative for the proper diagnosis and treatment of several neurological disorders. Telemetric sensors have shown their utility for ICP estimation in short-term monitoring in humans. However, their long-term reliability is uncertain. The authors present the case of a 37-year-old woman diagnosed with benign intracranial hypertension and obesity. The patient underwent gastric bypass surgery for ICP control. In order to monitor ICP before and after bariatric surgery, a Neurovent-P-tel sensor was implanted in the left frontal lobe. After gastric bypass, normal ICP values were recorded, and the patient’s visual fields improved. However, the patient experienced incapacitating daily headaches. The authors decided to implant a Codman Microsensor ICP transducer in the right frontal lobe to assess the long-term reliability of the Neurovent-P-tel measurements. A comparison of the recordings at 24 and 48 hours showed good correlation and reliability during long-term monitoring with the Neurovent-P-tel, with minimal zero drift after 11 months of implantation.
