Introduction. Alexia without agraphia is an impairment of reading ability. Speech, auditory comprehension, repetition and writing are relatively intact. Due to a damage of the splenium of corpus callosum, alexia without agraphia is considered to be an interhemispheric disconnection syndrome. Case Report. We presented a 71-year-old male, with chronic hypertension, diabetes mellitus and dyslipidemia. The magnetic resonance imaging showed a lesion in the left medial temporal region, including the equilateral thalamus, posterior cingulate gyrus, splenium of corpus callosum, lingual occipital gyrus, and the tail of the hippocampus. Lacunar ischemia was found on the right side of cerebellum. The neuro-linguistic diagnostic protocol included the Mini Mental State Examination, Boston Diagnostic Aphasia Examination, Boston Naming Test and phonemic and category fluency tests. We have also designed a clinical protocol for color recognition assessment. The results showed a mild cognitive impairment related to the time and space orientation, delayed memory and reading. On the speech and language levels, a severe acquired alexia without agraphia was registered which was not associated with other language modalities. Conclusion. The neuro-linguistic tests and clinical techniques provide a rather reliable diagnostic criteria, which is the basis for neuro-rehabilitation. The rehabilitation protocol refers to training techniques: tactile-kinesthetic recognition of graphemes and application of various reading techniques, such as letter-by-letter reading, Multiple Oral Re-reading, melodic intonation therapy and oral reading technique in order to facilitate rehabilitation of reading.

Abstract Background White matter hyperintensities (WMH) are frequently found in Alzheimer’s disease (AD). Commonly considered as a marker of cerebrovascular disease, regional WMH may be related to pathological hallmarks of AD, including beta-amyloid (Aβ) plaques and neurodegeneration. The aim of this study was to examine the regional distribution of WMH associated with Aβ burden, glucose hypometabolism, and gray matter volume reduction. Methods In a total of 155 participants (IMAP+ cohort) across the cognitive continuum from normal cognition to AD dementia, FLAIR MRI, AV45-PET, FDG-PET, and T1 MRI were acquired. WMH were automatically segmented from FLAIR images. Mean levels of neocortical Aβ deposition (AV45-PET), temporo-parietal glucose metabolism (FDG-PET), and medial-temporal gray matter volume (GMV) were extracted from processed images using established AD meta-signature templates. Associations between AD brain biomarkers and WMH, as assessed in region-of-interest and voxel-wise, were examined, adjusting for age, sex, education, and systolic blood pressure. Results There were no significant associations between global Aβ burden and region-specific WMH. Voxel-wise WMH in the splenium of the corpus callosum correlated with greater Aβ deposition at a more liberal threshold. Region- and voxel-based WMH in the posterior corpus callosum, along with parietal, occipital, and frontal areas, were associated with lower temporo-parietal glucose metabolism. Similarly, lower medial-temporal GMV correlated with WMH in the posterior corpus callosum in addition to parietal, occipital, and fontal areas. Conclusions This study demonstrates that local white matter damage is correlated with multimodal brain biomarkers of AD. Our results highlight modality-specific topographic patterns of WMH, which converged in the posterior white matter. Overall, these cross-sectional findings corroborate associations of regional WMH with AD-typical Aß deposition and neurodegeneration.

AbstractMyositis ossificans (MO) is a benign soft-tissue lesion characterized by the heterotopic formation of the bone in skeletal muscles, usually due to trauma. MO is occasionally difficult to diagnose because of its clinical and radiological similarities with malignancy. We report a case of traumatic MO (TMO) in the masseter and brachial muscles of a 37-year-old man who presented with painless swelling in the left cheek and severe trismus. Due to the absence of a traumatic history at the first consultation and identification of a tumorous lesion in the left masseter muscle by magnetic resonance imaging (MRI), the lesion was suspected to be a malignant tumor. Subsequently, 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG-PET/CT) showed multiple regions of high FDG uptake across the whole body, suggestive of multiple metastases or other systemic diseases. However, intramuscular calcifications were also observed in the left masseter and brachial muscles, overlapping the areas with high FDG uptake. Moreover, multiple fractures were seen in the rib and lumbar spine, also overlapping the areas with high FDG uptake. Based on these imaging findings, along with a history of jet-ski trauma, TMO was suspected. The left cheek mass was surgically excised and histologically diagnosed as TMO. In this case report, FDG-PET/CT could detect multiple TMOs across the whole body. To the best of our knowledge, cases of multiple TMOs located far apart in different muscles are rare, and this may be the first report.
