Pseudoperipheral palsy: a case of subcortical infarction imitating peripheral neuropathy
نویسندگان
چکیده
BACKGROUND Vascular damage in the central hand knob area can mimic peripheral motor nerve deficits. CASE PRESENTATION We describe the case of a woman presenting with apparent peripheral neuropathy. Brain magnetic resonance imaging and computed tomography angiography revealed an infarct in the precentral hand knob area, with significant stenosis in the right proximal middle cerebral artery trunk. Subsequent 3-Tesla magnetic resonance imaging of the brain suggested cerebral angiitis. The patient experienced improved hand function following combined glucocorticoid and cyclophosphamide treatment. CONCLUSION Vascular damage in the hand knob area should be considered when evaluating peripheral motor nerve deficits in the presence of normal nerve conduction velocities. The diagnosis of cerebral angiitis remains a major challenge for clinicians.

SUMMARY Spinal cord compression due to extramedullary hematopoietic tissue although very rare, is a well known phenomenon. The first case of spinal cord compression due to E.M.H.P. tissue in thalassemia was reported in 1954 by Gatto et al. Sinc then about 59 cases have been reported in literature. We present a new case who has been hospitalized in neurologic ward in Loghman -e- Hakim Hospital ...

Leptospirosis, a disease of great significance in tropical countries, presents commonly as a biphasic illness with acute febrile episode in the first phase followed by a brief afebrile period and then by the second phase of fever with or without jaundice and renal failure. However, it has varied manifestations and unusual clinical features ascribed to immunological phenomena can occur due to th...

We describe a patient who presented with an acute paresis of her distal right hand suggesting a peripheral median nerve lesion. However, on clinical examination a peripheral origin could not be verified, prompting further investigation. Diffusion-weighted magnetic resonance imaging revealed an acute ischaemic lesion in the hand knob area of the motor cortex. Isolated hand palsy in association w...
