Bilgisayarlı tomografide akut epidural hematomu taklit eden iyatrojenik subdural hematom

Öz

Subdural hematom ve epidural hematomun bilgisayarlı tomografi görüntüleri iyi tanımlanmıştır, bunlar sırasıyla hilal ve mercek şeklinde görüntü oluşturmaktadırlar. Bununla birlikte nadir durumlarda bunların birbirlerini taklit edebileceği bildirmiştir. Literatürde epidural hematomu taklit eden 7 sunum mevcuttur. Bu yazıda 75 yaşında bir erkek hastada kronik subdural hematom boşaltılmasını takiben gelişen radyolojik olarak epidural hematomu taklit eden yeni bir subdural hematom olgusu sunulacaktır.

Iatrogenic subdural hematoma mimicking acute epidural hematoma on computed tomography

Abstract

Computed tomography images of the subdural and epidural hematoma are well defined, crescent and lentiform shapes, respectively. However, it has been reported that both of them might mimic each other in rare instances. Literature reveals seven reports subdural hematoma mimicking epidural. We are reporting a new case of subdural hematoma mimicking epidural hematoma radiologically, which occurred after evacuation of chronic subdural hematoma with burr-hole in a 75 years old man. J Clin Exp Invest 2013; 4 (3): 367-369

Keywords

• Subdural hematoma, epidural hematoma, computed tomography, brain.
