Cerebral Tumour Presenting with Hyperventilation.
An unmarried man aged 51 had suffered from chronic bilateral anterior and posterior uveitis of unknown aetiology for seven years. Because the condition was poorly controlled with atropine and local steroids, oral Prednisone, 60 mg. daily, was added to the treatment and the dose was progressively reduced over three months to 35 mg. daily. Supplementary protein and potassium were given and the ca...
متن کاملHyperventilation and cerebral blood flow.
Hyperventilation and Cerebral Blood Flow • Hypocapnic-hyperventilation has a profound, but probably temporary, effect on CBF, producing approximately a 2% decline in CBF for each 1 torr decline in Pcov Th' effect appears to be mediated through changes in perivascular pH of the cerebral resistance vessels acting directly on the vessel wall. At low PC0;( the vasoconstrictor effect of short-term h...
متن کاملHyperventilation, cerebral perfusion, and syncope.
This review summarizes evidence in humans for an association between hyperventilation (HV)-induced hypocapnia and a reduction in cerebral perfusion leading to syncope defined as transient loss of consciousness (TLOC). The cerebral vasculature is sensitive to changes in both the arterial carbon dioxide (PaCO2) and oxygen (PaO2) partial pressures so that hypercapnia/hypoxia increases and hypocapn...
متن کاملRecurrent Primary CNS Lymphoma Presenting with Central Neurogenic Hyperventilation
Background: Tumor-induced Central Neurogenic Hyperventilation (CNH) is exceedingly rare, about half resulting from Primary CNS Lymphoma (PCNSL) despite their rarity. Results: We present a 75 year-old, immunocompetent woman with recurrent PCNSL leading to CNH. She was initially diagnosed with PCNSL via biopsy of the single enhancing left caudate focus among diffuse, nonenhancing CNS infiltrative...
متن کاملLymphomatoid granulomatosis presenting as central neurogenic hyperventilation.
A patient with lymphomatoid granulomatosis and focal transformation to lymphoma limited to the central nervous system presented with severe central neurogenic hyperventilation. The hyperventilation resolved as the underlying pathologic condition was treated with prednisone and cyclophosphamide.
