Figure 1a,b,c: MRT, Case 1
Legend:
(left) MRT of the 29-year-old male, 3 weeks after the accident.
Diffusion-weighted (DWI) sequences (b=1000) demonstrated multifocal
areas of abnormal bright signal along the corpus callosum and within the
left corona radiate and body of caudate nucleus corresponding to axonal
injuries after the trauma. (Middle) On T2*-sequences multifocal areas of
punctiform susceptibility artefacts (white arrow) at the grey-white
matter junction, more pronounced at the left parietal region, in the
corpus callosum and the temporal lobe (not shown) were visible,
indicating small foci of posttraumatic bleeding. (Right) Follow-up MR 18
months later showed that the oedematous areas on DWI-sequences and the
microbleeds had been resolved. The size of the ventricles and the sulci
seem to be a bit wider than right after the accident.
Figure 2a,b: CCT scan, Case 2
Legend:
Cranial CT of a 30-year-old male, 1 day after the accident (left image)
demonstrates extensive oedematous swelling within the anterior
cerebellar lobes as well as in both posterior temporal and occipital
lobes due to extensive hypoperfusion of the posterior circulation. The
cerebellar tentorium (right image) is slightly bowed upwards and a
slight compression of the basal cistern and the IV.ventricle is shown,
however liquor flow was patent.
