[Radiological diagnosis of basal inflammatory processes in the brain (arachnoiditis, arachnoencephalitis) in paranasal sinusitis].

The article presents radiological signs of basal processes (arachnoiditis, arachnoencephalitis) associated with paranasal sinusitis. gamma-Topography of the brain in inflammatory processes is distinguished by such typical radiological signs as a pathological accumulation of a radiopharmaceutical which is more often diffuse in nature. According to the findings of radionuclide cysternography the inflammatory process is characterized by a block of the subarachnoidal space of the frontobasal portions and an impairment of the CSF dynamics.
