ABSTRACT

OBJECTIVE AND IMPORTANCE Cranial epidural abscess mostly follows sinusitis or mastoiditis, also open cranial injury or cranial surgery with iatrogenic infection. In our case the abscess possibly evolved from epidural haematoma and the process invaded frontal sinus and subgaleal space in the frontal region. CLINICAL PRESENTATION A 22-year-old male after motorcycle accident 4 years ago, with signs of sinusitis frontalis and seizures, with CT confirmed epidural abscess. INTERVENTION Craniotomy was performed and the abscess totally removed. Homogeneous bone was replaced at the operation. Good result, after 2 months without pathologic signs and correct postoperative tomography. CONCLUSION: We conclude on the basis of disease history and clinical evidence, that the most probable was transformation of the abscess from epidural haematoma end in long term period perforated through the frontal bone to the frontal sinus, and to the subgaleal space with signs of sinusitis at last.
