BACKGROUND: Multinodular and Vacuolating Neuronal Tumor (MVNT) of the cerebrum is a benign lesion described recently in the WHO CNS tumours in 2016. Although this tumour is uncommon, clinicians should be acquainted with the possible presentation and imaging findings. CASE REPORT: We present a case of a young gentleman whose only symptom was absence seizures. Brain imaging showed lesions, compatible with this rare diagnosis. CONCLUSION: Our description of imaging findings on MRI highlights the characteristic cystic appearances of note in the right occipital lobe, in contrast to the temporal lobe as the predominant location found in previous cases.

Rare Diagnosis

There are many causes of a persistent unilateral numbness of the lower lip. A case report of a 34-year-old normally fit and well male, whose symptoms of numbness of the mandibular division of the right trigeminal nerve represented the rare diagnosis of a primary B-cell lymphoma of the mandible, is presented here. The patient's presentation and management, reasons for the difficulty in ascertaining a definitive diagnosis, as well as invaluable points to be reflected on from this case, are discussed. CPD/Clinical Relevance: Numbness should be treated with a high degree of suspicion, with urgent imaging, biopsy and specialist histopathology staining being carried out to exclude malignancy.

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.

Introduction : Double hearing or Diplacusis is a synchronous double perception of a sound and can have Binauralis or Monauralis pattern, with inner ear disorders being the main culprit [1] . Other forms of Auditory illusions have been reported as a co‐manifestation of stroke syndromes, but none as an isolated presentation [1][2] . This is a case of a 77‐year‐old male with acute onset isolated Diplacusis in a patient due to a right temporal lobe ischemic infarct. To our knowledge, this is the first case report of an isolated diplacusis due to cortical infarct. Methods : A case presentation with Pubmed search of review articles and case reports. Results : The patient had a past medical history of sensorineural deafness in his left ear. He described any sound heard as the same quality but occurring with an echo heard a fraction of a second later in his right ear. There was no decreased hearing quality or tinnitus reported in his right ear. His drug screen test was negative. His examination was only remarkable for a sensorineural hearing loss pattern on his left ear. His (NIHSS) was zero, and no other cranial nerve abnormalities were detected. His MRI was significant for a punctate restricted diffusion on the right temporal lobe, resembling an ischemic infarct (Figure). Conclusions : Isolated diplacusis can present as acute ischemic stroke in the temporal lobe. Further studies are needed to understand its pathophysiology.

Object Outcomes following functional hemispherotomy in patients with drug-resistant epilepsy have been well described. However, studies reporting long-term longitudinal outcomes after subhemispheric disconnective epilepsy surgery are still limited. Methods The authors conducted a retrospective review of prospectively collected data of 10 children who underwent temporoparietooccipital (TPO) disconnective surgery at the Vienna Pediatric Epilepsy Center. Results There were 3 males and 7 females (median age 8.7 years; range 4.2–22.1 years). The affected hemisphere was the left in 3 patients and the right in 7. The patients' median age at seizure onset was 3.0 years (range 0.2–8.3 years). The median duration of epilepsy before surgery was 5.2 years (range 1.3–17.2 years). The underlying pathology was TPO malformation of cortical development in 5 patients, and venous infarction, posterior hemispheric quadrant atrophy, Sturge-Weber syndrome, cortical involvement of a systemic lupus erythematosus, and gliosis after cerebral tumor treatment in 1 each. In 6 children, a pure TPO disconnection was performed; in 2 patients, the temporal lobe was resected and parietooccipital disconnection was performed. The 2 remaining patients had had previous epilepsy surgery that was extended to a TPO disconnection: disconnection of the occipital lobe (n = 1) and resection of the temporal lobe (n = 1). The authors encountered no complications while performing surgery. No patient needed blood replacement therapy. No patient developed CSF disturbances that warranted treatment. Nine of 10 patients are currently seizure free since surgery (Wieser Class 1a) at a median follow-up time of 2.1 years (range 4 months to 8.1 years). Conclusions Temporoparietooccipital disconnection is a safe and effective motor-sparing epilepsy surgery in selected cases. Technical adjuncts facilitate a better intraoperative visualization and orientation, thereby enabling a less invasive approach than previously suggested.

Introduction. Mesenchymal hamartoma of the liver is a benign lesion presenting as an enlarging abdominal mass in children less than 2 years of age. Fewer than 5% cases are present in individuals over 5 years of age, and this lesion is extremely rare in adults. It may affect the left or the right lobe of liver as a cystic or solid mass or both components may be present. The pathogenesis remains incompletely understood, but these lesions have generally been considered to represent a development abnormality in the bile duct plate formation. Case Report. In this report, we present a case of a 44-year-old man who was surgically treated at the Department of Abdominal, Endocrine and Transplantation Surgery of the Clinical Center of Vojvodina due to cystic lesion in the liver segment IV that had been verified by computed tomography imaging diagnostics. The patient was sent from a smaller health center with the diagnosis of echinococcosis. After the adequate preparation of the patient, surgical excision of the liver cystic lesion was done. Once a thorough histological examination had been performed, the diagnosis of mesenchymal hamartoma was made. Conclusion. Mesenchymal hamartoma of the liver is a benign tumor resulting from abnormal, intra-uterine development of bile ducts and has a delayed clinical manifestation, thus this lesion appears to be related to the processes of maturation. It is potentially premalignant lesion presenting as a solid and/or cystic neoplasm. Symptoms, laboratory results and radiographic imaging are nonspecific and inconclusive, so surgical excision of the whole lesion is the imperative for the definitive diagnosis.

Introduction: Melanocytoma of the optic disc is a benign lesion. Objective: To describe a case of optic disc melanocytoma Case: A 48-year old lady presented with gradual visual impairment associated with a floater. The right eye fundus examination showed a mass uniformly dark black in colour on the optic disc. The mass completely obscured the fluorescence on fluorescein angiography and was thus differentiated from malignant melanoma. Conclusion: Optic disc melanocytoma can present with visual impairment and a floater. Fluorescein angiography can be useful to differentiate between malignDOI: http://dx.doi.org/10.3126/nepjoph.v4i2.6553 Nepal J Ophthalmol 2012; 4 (2): 323-325
