Computed Tomography in Head Trauma

Abstract

Retrospective analysis of 200 cases of documented head trauma demonstrated an accuracy approaching 100% in the diagnosis of intra- and extracerebral collections of blood. Caution must be exercised in the evaluation of trauma 1 to 5 weeks old, since subdural hematomas have the same density as normal brain tissue, and angiography may be necessary. The clinical diagnosis of brainstem contusion is associated with a remarkably high level (54%) of surgically correctable lesions. The use of computed tomography in the evaluation of other traumatic intracranial lesions is discussed.

Acute Epidural-Like Appearance of an Encapsulated Solid Non-organized Chronic Subdural Hematoma -Case Report-

“…A crescent shape and a density usually similar or lower to that of the adjacent cerebral parenchyma are the usual computed tomography (CT) features of both liquid and organized chronic SDHs. 6,19) In contrast, acute epidural hematomas are biconvex or lentiform shaped lesions with high-density content on CT without contrast medium. 5) We report on the rare case of an extracerebral hyperdense hematoma with a biconvex shape on CT that was diagnosed in an aged person who had suffered a rapid neurological deterioration and had no history of a recent head trauma.…”

Extravasation of Contrast Medium into Blood Clot in Acute Traumatic Intraventricular Hemorrhage

“…In the literature, traumatic intra ventricular hemorrhage was seen in 0.5-9% of head inj uries. [2][3][4][5][6][8][9][10][11][12]15) In the present cases, unique extravasation of con trast medium into the ventricular system occurred following contrast medium administration. As far as is known, few cases have shown extravasation of contrast medium into the ventricular system except for a 48-year-old female case reported by Tsai et al 12)…”

“…[2][3][4][5][6][8][9][10][11][12]15) In 1974, Scott et al,") first reported a case of traumatic intraventricular hemorrhage demonstrated by CT. In 1976, Merino-deVillasante and Taveras8) observed 3 cases of intraventricular hemorrhage among 100 patients with head injuries.…”

“…Such hemorrhages were sometimes confirmed only by a direct ventricular tap, surgery or autopsy .7 However, the widespread use of CT in the diagnosis of patients with acute head injuries has facilitated diagnosis of traumatic intraventricular hemorrhages because of its ability to visualize the entire intracranial con tents. [2][3][4][5][6][8][9][10][11][12]15) To the authors' knowledge, however, only few have reported the occurrence of intraventricular hemorrhage in blunt head trauma.") This paper presents 2 cases of acute traumatic intraventricular hemorrhage detected by CT within 2 hours after the trauma.…”

Primäre bildgebende Diagnostik von polytraumatisierten Patienten mittels Spiralcomputertomographie

“…Alle Diagnosen, die eventuell einer direkten neurochirurgischen Intervention bedürfen, wie epi-oder subdurale Blutungen oder ausgeprägte Impressionsfrakturen, lassen sich zügig und mit großer Zuverlässigkeit in ihrer Ausprägung darstellen (18,104).…”
