Increase in cross-sectional muscle area of major muscle groups associated by heavy resistance training
has been well documented. However, there has been no published article of changes in the inferior
orbicularis oculi muscle when heavy resistance training is applied. We present a case of inferior
orbicularis hypertrophy detected on MRI in a gentleman who practised heavy resistance training
using his lower eyelids.

Progressive multifocal leukoencephalopathy (PML) is a rapidly progressive demyelinating disease
caused by the reactivation of JC papova virus usually in immunocompromised hosts.1
The disease is
a chronic viral infection resulting in mortality within a year.2
The condition characterized by white
matter changes in multiple locations of the brain is caused by destruction of the oligodendrogliocytes.2
We report a case of AIDS associated PML presenting with progressive cerebellar symptoms, with the
unusual feature of imaging abnormalities limited to the posterior fossa.

Background and Objective: There is a great challenge to establish a level 4 epilepsy care offeringcomplete evaluation for epilepsy surgery including invasive monitoring in a resource-limited country.This study aimed to report the setup of a level 4 comprehensive epilepsy program in Malaysia and theoutcome of epilepsy surgery over the past 4 years. Methods: This is a retrospective study analyzingcases with intractable epilepsy in a comprehensive epilepsy program in University Malaya MedicalCenter (UMMC), Kuala Lumpur, from January 2012 to August 2016. Results: A total of 92 caseshad comprehensive epilepsy evaluation from January 2012 till August 2016. The mean age was 35.57years old (range 15-59) and 54 (58.7%) were male. There were 17 cases having epilepsy surgeryafter stage-1 evaluation. Eleven cases had mesial temporal sclerosis and 81% achieved Engel classI surgical outcome. Six cases had lesionectomy and 60% had Engel class I outcome. A total of 16surgeries were performed after stage-2 evaluation, including invasive EEG monitoring in 9 cases.Among those with surgery performed more than 12 months from the time of data collection, 5/10(50%) achieved Engel I outcome, whereas 2 (20%) had worthwhile improvement (Engel class III)with 75% and 90% seizure reduction.Conclusion: Level 4 epilepsy care has an important role and is possible with joint multidisciplinaryeffort in a middle-income country like Malaysia despite resource limitation.

Objective: The primary objective of this study was to describe the neuroimaging changes of tuberculous
meningitis (TBM), and to determine the role of neuroimaging in the diagnosis of TBM. Methods:
Between January 2009 and July 2015, we prospectively recruited TBM patients in two hospitals in
Malaysia. Neuroimaging was performed and findings were recorded. The control consists of other types
of meningo-encephalitis seen over the same period. Results: Fifty four TBM patients were recruited.
Leptomeningeal enhancement was seen in 39 (72.2%) patients, commonly at prepontine cistern and
interpeduncular fossa. Hydrocephalus was observed in 38 (70.4%) patients, 25 (46.3%) patients had
moderate and severe hydrocephalus. Thirty four patients (63.0%) had cerebral infarction. Tuberculoma
were seen in 29 (53.7%) patients; 27 (50.0%) patients had classical tuberculoma, 2 (3.7%) patients
had “other” type of tuberculoma, 18 (33.3%) patients had ≥5 tuberculoma, and 11 (20.4%) patients
had < 5 tuberculoma. Fifteen (37.2%) patients had vasculitis, 6 (11.1%) patients had vasospasm. Close
to nine tenth (88.9%) of the patients had ≥1 classical neuroimaging features, 77.8% had ≥ 2 classical
imaging features of TBM (basal enhancement, hydrocephalus, basal ganglia / thalamic infarct, classical
tuberculoma, and vasculitis/vasospasm). Only 4% with other types of meningitis/encephalitis had ≥1
feature, and 1% had two or more classical TBM neuroimaging features. The sensitivity of the imaging
features of the imaging features for diagnosis of TBM was 88.9% and the specificity was 95.6%.
Conclusion: The classic imaging features of basal enhancement, hydrocephalus, basal ganglia/thalamic
infarct, classic tuberculoma, and vasculitis are sensitive and specific to diagnosis of TBM.
