Abstract
-
BACKGROUND: Intracranial complications of paranasal sinus infection are rare and may be misdiagnosed during an initial evaluation because they often show subtle symptoms, which include elusive physical and neurological findings and imaging. The late recognition of these conditions and the delayed treatment can increase morbidity and mortality rates. We aimed to characterize the typical clinical features of intracranial complications associated with sinusitis.
METHODS
Twelve patients who visited the Eulji Medical Center from 1994 to 2000, with sinogenic suppurative intracranial lesions were reviewed. Medical records and radiological studies were reviewed retrospectively.
RESULTS
There were 12 cases with 15 sinogenic intracranial complications. The ratio of males to female was 2 : 1. The ages of patients ranged from 16 to 81 (average: 46.7). Four cases had meningitis, four had focal cerebritis, three had cavernous sinus throm-bophlebitis, two had subdural empyema, and two had epidural abscess or empyema. The primary lesions of paranasal sinusitis were located at the sphenoid in three, ethmoid sinus in two, frontal sinus in one and the multiple sinus in six. The outcome revealed complete recovery in six cases, mild neurologic sequelae in three cases, death in two cases and recurrence in one case.
CONCLUSIONS
The type of intracranial complication and origin of paranasal sinusitis may be changing. Cases in which such complications are suspected, in order for an early diagnosis, a MRI should be considered. The successful management of intracranial complications consists of timely antibiotics therapy combined with surgical drainage of the loculated infection. (J Korean Neurol Assoc 19(5):457~463, 2001)
