desmoplastic fibroma is a rare, locally aggressive, benign lesion. a case of desmoplastic fibroma of left side of mandible is reported. the lesion presented as painless mass in left posterior portion of mandible of a 7-year-old girl. histologically the lesion was composed of interlacing fascicles of benign appearing fibroblast in a varying ground substance of collagenous tissue. in this report,...

Intracerebral metastasis in osteosarcoma is extremely rare. A 14-year-old girl who had previously been operated upon for osteosarcoma of the femur presented with seizures and left hemiparesis. A right parietal lesion with calcification and brain oedema was found. After resection of the mass, pathology revealed an osteosarcoma metastasis.

Eight patients with a histologically proven angiographically occult arteriovenous malformation of the brain had plain and infused computed tomographic (CT) examinations. In five cases angiography revealed a hypovascular mass and in three cases the angiogram was normal. On CT examination a high density lesion (six cases) and ventricular asymmetry (five cases) were demonstrated. In three patients...

Split-brain monkeys underwent either deep hemispheric disconnection or unilateral cortical ablations in an attempt to determine the neural mechanisms underlying ipsilateral eye-hand coordination. The results indicate that the responding hand is not in any direct way controlled by visual processes of the ipsilateral hemisphere. Instead, it is suggested that the target information crosses over to...

OBJECTIVE We describe a patient with seronegative autoimmune limbic encephalitis (SNALE) masquerading as glioma. Brain magnetic resonance imaging (MRI) abnormalities, distinctive pathological findings, and spontaneous remission are highlighted. BACKGROUND There are 15 previously reported SNALE cases, 1 with pathology. MATERIALS AND METHODS A 66-year-old man presented with prominent amnestic...

We report a case of primary central nervous system vasculitis (PCNSV) mimicking a cortical brain tumor. A 25-year-old woman presented with a 2-week history of headache and transient right hemiparesis. Brain magnetic resonance imaging (MRI) revealed a cortical-involving lesion on the left frontal lobe. The 6-cm sized lesion showed low signal intensity on T1-weighted images and high signal intens...

W e present a case of a large solitary demyelinating plaque in the brain masquerading as tumour. A 34 year old healthy woman presented with sudden onset of left hemiparesis. Subsequent MRI of the brain showed a single large 2.5 cm right sided enhancing lesion within the white matter of the parietal lobe (fig 1). The lesion appeared to originate from the corpus callosum. Diffusion weighted and g...
