[An enormous epidural abscess secondary to cranial metastasis of a lung tumor].

Epidural abscess most often develops as a result of otitis media, sinusitis, and mastoiditis. In these cases, most of the time, pathogens enter the epidural space through the venous and arterial system, while during open fractures or neurosurgery, bacteria can also enter the skull bone and dura directly. Our case report can be considered a literary rarity, since the destruction of the cranium – caused by the metastasis of a lung tumor – played a role in the development of the enormous epidural abscess, which opened the non-sterile sinuses and mastoid system in the direction of the epidural space. The patient’s low compliance and chronic alcoholism played a role in the rapid deterioration. Orv Hetil. 2024; 165(2): 69–73.
