Five children (three males, two females; four right‐, one left‐handed; age range 6 to 14 years) who developed aphasia after gross‐total excision of left predominantly thalamic tumors are reported. Three patients had Broca aphasia, one had mixed transcortical aphasia, and one patient had conduction aphasia. In the months after surgery, three children improved while receiving radiation and/or chemotherapy, although none recovered completely. Two patients with malignant tumors developed worsening aphasia when the tumor recurred, and later died. Two of three patients tested had visuospatial difficulties in addition to language deficits. Attention and executive functioning were affected in three of three patients tested. Memory, verbal and/or visual functioning, were affected in four of four patients tested. Both patients who were tested showed transient right hemineglect. Two of two patients tested were probably apraxic. The wide range of deficits in these children highlights the import...

Global aphasia is an acquired language disorder During admission, her blood pressure was 200/110 mmHg and characterized by severe impairments in all modalities of pulse was 100/bpm. Neurological examination revealed confusion, language. The specific sites of injury commonly include central facial paresis, hemiparesis and positive Babinski's sign on Wernike's and Broca's areas and result from large strokes the right. Her confusion improved after a few days. Sensation,-particularly those involving the internal carotid or middle visual fields, praxis and visuospatial examinations could not be cerebral arteries. Rarely, deep subcortical lesions may evaluated due to her language disorder. CT scan showed a large cause global aphasia. We present three cases with global hemorrhage in the left thalamus extending to the anterolateral, aphasia due to a more rare cause: left thalamic posterolateral and medial areas of the thalamus and also anterior hemorrhage. Their common feature was the large size of superior and superior periventricular white matter (PVWM) the hemorrhage and its extension to the third ventricule. slightly compressing the third ventricle [Figure 1]. HMPAO-SPECT in one of the cases revealed ipsilateral First detailed language evaluation was done with the Gülhane subcortical, frontotemporal cortical and right frontal cortical aphasia test and the Turkish version of the Boston diagnostic hypoperfusion.

Thalamic injury from various natural causes, including tumours and haemorrhage, has been reported to lead to abnormalities of language. The pathophysiology of these language disorders remains controversial because the naturally occurring thalamic lesions often are associated with mass effects. Two patients are described with hypodense left thalamic lesions, shown by computed tomography, probably representing infarction. Both patients had aphasia, but neither had evidence of appreciable brain swelling or distortion, nor were cortical language areas damaged.

Object Functional involvement of the thalamus in cognitive processing has been only anecdotally reported in the literature, and these cases are mostly related to thalamic hemorrhages; there is no available information on cognitive development in children with thalamic tumors. Methods All children admitted with a diagnosis of thalamic tumor at the authors' institution between January 2008 and January 2011 were considered for the present study. Exclusion criteria were age less than 18 months and the presence of severe neurological deficits, both of which prevented a reliable neuropsychological evaluation. A complete preoperative neuropsychological evaluation was performed. Results Twenty children were selected (mean age 102.4 months). Total IQ was in the normal range in all patients (mean 90.1, SD 13.87) with a significant difference between verbal IQ (mean 97.70, SD 17.77) and performance IQ (mean 84.82, SD 17.01). A significant correlation was found between global cognitive impa...

Vascular lesion of the subcortical structures leads to aphasia. Cortical hypoperfusion has been proposed to be the etiological mechanism in aphasia following subcortical vascular lesion. Subcortical aphasia shows considerable variability in its clinical profile. Such variability has been attributed to the variable sites of cortical hypoperfusion following ischemic lesion of the subcortical structures. This study investigated the variability in clinical aphasic profile following subcortical hemorrhagic lesion. We retrospectively investigated the clinical aphasic profiles of twelve patients who reported to our hospital during a period of one year with subcortical hemorrhagic lesions. All patients underwent routine neurological examination, neuroimaging (CT/MRI) investigations and linguistic assessment. Eight patients exhibited lesion to the basal ganglia and four showed thalamic lesion. All of them showed considerable variability in their aphasic profile. Subcortical hemorrhagic lesio...

Language and speech function is commonly accepted to be a heavily lateralized function. Greater than 95% of right-handed individuals have left hemispheric dominance for language, and reports in the literature of crossed aphasia (language deficits in a right-handed individual from right-sided pathology) are scant. We report the case of a 52-year-old woman presenting with crossed aphasia from a right temporal glioblastoma. We then expand on a discussion of crossed aphasia in the setting of brain tumors.

We describe a patient (KO) with reduced spontaneous speech, resembling dynamic aphasia, after awake glioma surgery in the proximity of the supplementary motor area. Naming, repetition, and comprehension were intact. He was tested with an extensive neuropsychological test-battery and a protocol for dynamic aphasia at 1 year. He presented with postoperative reduced spontaneous speech and selective executive function deficits. Most language recovery took place at 3 months postoperatively, whereas the executive functions improved between 3 months and 1 year. Results suggest that resection near the supplementary motor area could increase the risk of cognitive disturbances at long term, especially language.

AbstractÐThree bilingual patients with ischemic or tumoral brain lesions localized in the left thalamus have been submitted to a thorough neurolinguistic analysis by means of the Bilingual Aphasia Test (BAT). They all presented with language impairments which included reduced verbal¯uency; phonemic, semantic and verbal paraphasias; grammatical errors (e.g. omission and addition of free grammatical morphemes); greater disruption of comprehension as opposed to repetition; and disorders of written language. In all patients, the most disrupted linguistic levels concerned morphology and syntax, more in L2 than in L1. One patient also presented with several mixing phenomena and major diculties in translating sentences. # 1997 Elsevier Science Ltd. All rights reserved
Background Aphasic symptoms are typically associated with lesions of the left fronto-temporal cortex. Interestingly, aphasic symptoms have also been described in patients with thalamic strokes in anterior, paramedian or posterolateral location. So far, systematic analyses are missing. Methods We conducted a retrospective analysis of consecutive patients admitted to our tertiary stroke care center between January 2016 and July 2017 with image-based (MRI) proven ischemic stroke. We evaluated stroke lesion location, using 3-T MRI, and presence of aphasic symptoms. Results Out of 1064 patients, 104 (9.8%) presented with a thalamic stroke, 52 of which (4.9%) had an isolated lesion in the thalamus (ILT). In patients with ILT, 6/52 had aphasic symptoms. Aphasic symptoms after ILT were only present in patients with left anterior lesion location (n = 6, 100% left anterior vs. 0% other thalamic location, p < 0.001). Conclusions Aphasic symptoms in thalamic stroke are strongly associated with left anterior lesion location. In thalamo-cortical language networks, specifically the nuclei in the left anterior thalamus could play an important role in integration of left cortical information with disconnection leading to aphasic symptoms.

Aims -The traditional description of the clinical picture of acquired childhood aphasia (ACA) claims that ACA is invariably nonfluent, that recovery of language disorder is rapid and complete, and that ACA commonly occurs after right hemisphere damage. However, since the late 1970s the publication of several case studies has led to reject this longstanding standard doctrine. This review, which concerns the revised insights into ACA, aims at making an inventory of the recently described aphasic symptomatologies and neuroradiological data. Material -The literature on ACA with emphasis on the studies published since 1978.

Background: Pneumocephalus is a common complication presented as air in the cranial cavity after cranial surgery. We present a very rare case of isolated new onset aphasia due to pneumocephalus after evacuation of subdural hematoma (SDH). Tension pneumocephalus presenting as isolated aphasia has not been reported earlier although associated paresis has been reported. Case presentation: We present the case of a 13-year-old male child with a history of fall before the onset of symptoms like headache and vomiting. The immediate MRI of the brain showed left-sided frontotemporoparietal subacute SDH with significant midline shift and subfalcine herniation. The child was subsequently managed with craniotomy and evacuation of hematoma with duraplasty. The patient developed aphasia on second-day postsurgery which progressed from moderate to severe aphasia by day 4. Computed tomography (CT) scan revealed pneumocephalus and an increase in the pneumocephalus in imaging on post-op day 4 with no other abnormalities. The condition was then managed by removing the subgaleal drain and administering high flow oxygen of 10 l/min. Conclusion: This case signifies the importance of proper diagnosis of new-onset neurological deficits after evacuation of subdural hematoma for the better outcome.

P to 5% of pediatric intracranial tumors occur in the thalamic region. The management regimen for children with tumors in this region is not clear-cut. The existing literature is sparse and difficult to interpret because many series combine both adult and pediatric populations, 2,16,22,27,32,34 or they include tumors arising in the basal ganglia and other diencephalic structures. In the few series in which purely thalamic tumors in children are addressed, the cases are often confined to one histological group, usually astrocytic tumors.
We would like to dedicate this study to our families, supervisor, and friends.

Crossed aphasia in dextrals (CAD) following pure subcortical lesions is rare. This study describes a right-handed patient with an ischemic lesion in the right thalamus. In the post-acute phase of the stroke, a unique combination of ‘crossed thalamic aphasia’ was found with left visuo-spatial neglect and constructional apraxia. On the basis of the criteria used in Mariën et al. [67], this case-report is the first reliable representative of vascular CAD following an isolated lesion in the right thalamus. Furthermore, this paper presents a detailed analysis of linguistic and cognitive impairments of ‘possible’ and 'reliable' subcortical CAD-cases published since 1975. Out of 25 patients with a pure subcortical lesion, nine cases were considered as ‘possibly reliable or reliable’. A review of these cases reveals that: (1) demographic data are consistent with the general findings for the entire group of vascular CAD, (2) the neurolinguistic findings do not support the data in the...

metastasis, or meningioma. Although the glioblastoma group had the greatest improvements in WAB operative scores, 57% remained dysphasic after resective surgery. Two additional patients declined postoperative assessment. Interpretation Resective surgery for left-sided intracranial tumours significantly improves language function in dysphasic patients, and is unlikely to impair language functions in non-dysphasic patients. Dysphasia and its response to resective surgery are related to the tumour neuropathology.
