High-resolution CT diagnosis of emphysema in symptomatic patients with normal chest radiographs and isolated low diffusing capacity.

abstract：:Three patients presented with meningitis associated with congenital defects of the inner ear, consisting of a cyst-like cochlea and a short, wide horizontal semicircular canal. The findings were easily identified on routine skull radiographs, alleviating the need for further studies and leading to treatment of the def...
