[Diagnostic problems in coexistence of paranasal sinusitis with cerebral tumor].

Differential diagnosis between the intracranial complications of paranasal sinusitis and cerebral tumor belongs to very difficult tasks in otolaryngology and neurosurgery. Complications of sinusitis, such as intracranial abscess formation, are uncommon and often clinically unremarkable. The arising difficulties are even greater in inflammatory intracranial complications of sinusitis, giving symptoms similar to those of cerebral tumors. The illustrative case report was presented.
