The study objective is to report 2 cases of endoscopic transsphenoidal removal of hypothalamic hamartomas (HH). This surgical method has not been previously considered in both Russian and foreign publications. Materials and methods. A 16-year-old male patient (R.) was admitted to hospital with complaints of epileptic seizures occurring once every 5–6 days; the disease duration was 9 years. A 23-year-old female patient (M.) was also admitted to hospital with complaints of epileptic seizures occurring once a week; the disease duration was 16 years. Results. Magnetic resonance imaging of the brain of patient R. revealed a HH (1.5 cm × 1.4 cm × 1.4 cm) and focal cortical dysplasia in the right occipital lobe. During a 3-day video electroencephalogram monitoring, we registered 3 secondary generalized complex partial seizures. Patient R. underwent endoscopic transsphenoidal removal of the HH. After surgery, he experienced no epileptic seizures during the next 18 months, even though he continued to receive the same doses of antiepileptic drugs. Magnetic resonance imaging of the brain of patient M. demonstrated a HH (2.44 cm × 2.79 cm × 2.68 cm). During a 4-day video electroencephalogram monitoring, we registered 2 secondary generalized complex partial seizures. The patient underwent transsphenoidal removal of the HH. During the next 8 months, the patient experienced no seizures. Conclusion. Our results suggest that transnasal removal of HH is a highly effective and safe procedure for patients with drug-resistant epilepsy. Surgical removal of HHs ensures effective control of the disease, which was previously resistant to pharmacotherapy.

Background:We describe the presentation of a young woman with long-standing complex partial seizures with occasional secondary generalization, who presented with complex visual hallucinations (CVHs) and delusions.Methods:Routine biological workup including magnetic resonance imaging revealed an area of significant left-sided occipital gliosis. Video telemetry monitoring revealed a left occipital focus for the origin of the electrographic seizure discharge.Conclusion:CVHs occur in a range of organic states, including epilepsy, and can be understood in terms of the underpinning neuroanatomy and neurotransmitter systems of the visual system.

Background Acute dizziness may be the only symptom of stroke. Prevalence of this disease among patients with isolated dizziness differs significantly and depends on study design, inclusion criteria and diagnostic methods. In available investigations, we did not find any prospective studies where magnetic resonance imaging, positional maneuvers, and Halmagyi-Curthoys test had been used to clarify a pattern of diseases with isolated acute dizziness and suspected stroke.Aim of study To clarify the pattern of the causes of dizziness in patients with suspected acute stroke.Material and methods We examined 160 patients admitted to N.V. Sklifosovsky Research Institute for Emergency Medicine with suspected stroke and single or underlying complaint of dizziness. All patients were examined with assessment of neurological status, Dix-Hollpike and Pagnini-McClure maneuvers, HalmagyiCurthoys test, triplex scans of brachiocephalic arteries, transthoracic echocardiography, computed tomography (CT) and magnetic resonance imaging (MRI) of the brain with magnetic field strength 1.5 T. MRI of the brain was performed in patients without evidence of stroke by CT and in patients with stroke of undetermined etiology according to the TOAST classification.Results In 16 patients (10%), the cause of dizziness was a disease of the brain: ischemic stroke (n=14 (88%)), hemorrhage (n=1 (6%)), transient ischemic attack (TIA) of posterior circulation (n=1 (6%)). In 70.6% patients (n=113), the dizziness was associated with peripheral vestibulopathy: benign paroxysmal positional vertigo (n=85 (75%)), vestibular neuritis (n=19 (17%)), Meniere’s disease (n=7 (6%)), labyrinthitis (n=2 (1,3%)). In 6.9% patients (n=11), the cause of dizziness was hypertensive encephalopathy, 1.9% of patients (n=3) had heart rhythm disturbance, 9.4% of patients (n=15) had psychogenic dizziness, 0.6% of patients (n=1) had demyelinating disease, and 0.6% of patients (n=1) had hemic hypoxia associated with iron deficiency anemia.Conclusion In 70.6% patients with acute dizziness, admitted to hospital with a suspected stroke, peripheral vestibulopathy was revealed. Only 10% of patients had a stroke as a cause of dizziness.
