ABSTRACT

Background and Objectives: We aimed to determine the link between brain volumetry results and functional disability calculated using the Expanded Disability Status Scale (EDSS) among multiple sclerosis (MS) patients in relation to the provided treatment (disease-modifying therapies (DMTs)) during a 5-year follow-up period. Materials and Methods: A retrospective cohort study was performed enrolling 66 consecutive patients with a confirmed diagnosis of MS, predominantly females (62% (n = 41)). Relapsing-remitting (RR) MS was noted in 92% (n = 61) of patients, with the rest being patients with secondary progressive (SP) MS. The mean age was 43.3 years (SD 8.3 years). All patients were evaluated clinically using the EDSS and "FreeSurfer© 7.2.0" radiologically during a 5-year follow-up. Results: A significant increase in patient functional disability was noted, calculated using the EDSS during a 5-year follow-up. The baseline EDSS ranged between 1 and 6 with a median of 1.5 (IQR 1.5-2.0), and after 5 years, the EDSS was between 1 and 7, with a median EDSS of 3.0 (IQR 2.4-3.6). Compared with RRMS patients, SPMS patients demonstrated a significant increase in EDSS score during a 5-year period, with a median EDSS of 2.5 in RRMS patients (IQR 2.0-3.3) and 7.0 (IQR 5.0-7.0) among SPMS patients. Significantly lower brain volumetry results in different brain areas were found, including cortical, total grey and white matter, p < 0.05. Statistically significant differences were observed between baseline volumetry results of the hippocampus and the middle anterior part of the corpus callosum and their volumetry results after 5 years, p < 0.001. In this study population, the thalamus did not demonstrate significant changes in volumetry results during follow-up, p > 0.05. The provided treatment (DMTs) did not demonstrate a significant impact on the brain MRI volumetry results during a 5-year follow-up, p > 0.05. Conclusions: Brain MRI volumetry seriously impacts the early detection of brain atrophic changes. In this study, significant relationship between brain magnetic resonance volumetry results and disability progression among MS patients with no important impact of the provided treatment was described. Brain MRI volumetry may aid in the identification of early disease progression among MS patients, as well as enrich the clinical evaluation of MS patients in clinical patient care.

ABSTRACT

BACKGROUND Neurosyphilis is a central nervous system infection caused by Treponema pallidum, that can develop at any time after the initial infection. The clinical signs of neurosyphilis are very variable, as well as its radiological features, and it is a diagnostic challenge. Knowledge of clinical symptoms and correct laboratory diagnostics, combined with routine radiological examination and additional diagnostic tools, such as high-resolution, three-dimensional FLAIR sequence, T2-weighted, and T1-weighted contrast-enhanced magnetic resonance imaging (MRI) are key to making an accurate diagnosis of neurosyphilis. CASE REPORT We present the clinical case of a patient who presented a 1-year history of vague clinical symptoms and was misdiagnosed with herpes simplex virus (HSV) encephalitis. Initial head MRI revealed extensive cerebral white matter lesions with cortical contrast enhancement, mainly of anterior and medial parts of the left temporal lobe, as typically seen in HSV encephalitis. Empirical therapy with acyclovir was started until a diagnosis of syphilis was confirmed with laboratory findings. Later, the therapy was changed to penicillin G. The patient's condition improved after receiving targeted treatment. A control MRI scan was performed, and previously detected changes in the brain had decreased significantly. CONCLUSIONS MRI is the imaging of choice to support the diagnosis of neurosyphilis. Our findings suggest that neuroimaging can play an important role in indicating suspicion of syphilitic encephalitis. Enhancement of the anterior and medial parts of the temporal lobe is an atypical imaging finding, and it can simulate an infection with HSV. Early treatment is critical to a positive outcome.
