T1 - Hyperintense Marklagerläsionen bei psychiatrischen Patienten: räumliche Verteilung und psychopathologische Symptome T1 - Hyperintense white matter lesions in psychiatrie patients: spatial distribution and psychopathological symptoms N2 - In einem Kollektiv von 130 MR-tomographisch untersuchten psychiatrischen Patienten (axiale T2-SE-Sequenz) wurden Zahl und räumliche Verteilung von hyperintensen Marklagerläsionen ("white matter lesions"; WM L) erfaßt und die Ventricle-to-brain-Ratio (VBR) bestimmt. Eine Konfigurationsfrequenzanalyse auf der Grundlage der räumlichen WMLVerteilung erlaubte die Abgrenzung von vier Patientengruppen: 1. keine WML (n = 35), 2. WML rechts frontotemporal (n = 23), 3. WML bifrontal (n = 12), 4. WML ubiquitär (n = 16). Die während 3 Jahren beobachteten psychopathologischen Symptome dieser Patienten wurden retrospektiv nach dem AMDP-Systemdokumentiert. In der Gruppe mit ubiquitären WML überwogen organisch-psychopathologische Ttems, die VER war größer als in den anderen Gruppen (ANOVA;p < 0,001). Die räumliche W M L- Verteilung erklärte 10,24 % der Gesamtvarianz psychopathologischer M erkmalsverteilung in den Gruppen. Das Patientenalter (MANCOVA; p < 0,021), nicht aber die VER hattesignifikanten Einfluß auf das psychopathologische Symptomprofil. Nach Ausblendung der Patientengruppe mit ubiquitären WMLblieb der Einfluß der WML-Verteilung auf die psychopathologische Symptomatiksignifikantc (p <0,05). Bifrontale WML waren mit Denkstörung, rechts frontotemporale WML mit affektiven Symptomen assoziiert. Die Befunde sprechen für einen Einfluß der räumlichen Verteilung unspezifischer Marklagerläsionen auf die psychopathologische Symptomatik. N2 - In a sampie of 130 patients who had undergone MRI (transverse TIweighted SE sequenee) patchywhite matter lesions (WML) were documented according to number and spatial distribution in the brain. Ventricle-to-Brain Ratio (VBR) was determined. Configural frequency analysis led to delineation of four patient groups on the basis of WML 10-cation: 1. no WML (n = 35), 2. right frontal-temporal WML (n = 23), 3. bifrontal WML (n = 12),4. WML in all/all but one brain region (n = 16). Psychopathological symptoms reported in the course of a maximum of 3 years were documen ted by chart review. In the 'pervasive WML' group psychopathological items characteristic of organic brain syndromes prevailed, mean VER exceeded values in all other groups (ANOVA, p < 0.001). WML spatial distribution accounted for 10.2 % oftotal psychopathological variance. Patient age, but not VER, had a significant impact on symptom profile (MANCOVA). When the 'pervasive WML' group was excluded, the finding of a significant effect of WML location on psychopathological symptom profiles was robust. Bifrontal WML were associated with thought incoherence, right frontal-temporal WML with affective symptoms. Findings support an impact of spatial distribution of unspecific WML on psychopathological symptoms in psychiatrie patients.

This disease has low prevalence and remains underreported in Europe. Emerging clinical data show that diagnostic difficulties are still common. We report on a 76-year old patient suffering from AE lesions restricted to the left lobe of the liver who underwent a curative extended left hemihepatectomy. Prior to the resection a liver biopsy under the suspicion of an atypical malignancy was performed. After the intervention he developed a pseudoaneurysm of the hepatic artery that was successfully coiled. Surprisingly, during surgery, the macroscopic appearance of the tumour revealed a growth pattern that was rather typical for cystic echinococcosis (CE), i.e., a gross tumour composed of multiple large vesicles with several centimeters in diameter. In addition, there were neither extensive adhesions nor infiltrations of the neighboring pancreas and diaphragm as was expected from previous imaging results. The unexpected diagnosis of AE was confirmed by definite histopathology, specific polymerase chain reaction and serology results. This is a rare case of unusual macroscopic presentation of AE that posed immense diagnostic challenges and had an eventful course. To our knowledge this is the first case of an autochthonous infection in this particular geographic area of Germany, the federal state of Saxony. This report may provide new hints for an expanding area of risk for AE and emphasizes the risk of complications in the scope of diagnostic procedures and the limitations of modern radiological imaging.
