Subdural abscess complicating frontal sinusitis is an important yet little recognized entity. It is mentioned infrequently as being of pathologic interest and hardly ever is thought of as warranting clinical consideration. The numerous other conditions that often precede, accompany or follow subdural abscesses have tended to overshadow the significance of the latter and to obscure the fact that the development of a subdural abscess may be one of the most important stages in the progression of an infection which, if unchecked, is fatal.
