OBJECTIVE The purpose of our study was to evaluate quantitative multiphasic CT enhancement patterns of malignant renal neoplasms to enable lesion differentiation by their enhancement characteristics. We used a new method to standardize enhancement measurement in lesions on multiphasic CT not being influenced by intrinsic factors like cardiac output. (More)
Catumaxomab, the first anti-EpCAM antibody, was approved in 2009 for the treatment of malignant ascites in cancer patients with EpCAM positive tumors. We consider this case of interest as treatment with catumaxomab not only prolonged the puncture-free interval but also showed a systemic effect in a patient with metastasized colorectal cancer by regression(More)
Although recurrence of primary spontaneous pneumothorax (PSP) is frequent, guidelines do not routinely recommend surgery after first presentation. A CT-based lung dystrophy severity score (DSS) has recently been proposed to predict recurrence following conservative therapy. This study compares the DSS in surgically and conservatively treated patients. This(More)
OBJECTIVE To prospectively analyse the diagnostic value of semi-quantitative breast-specific gamma imaging (BSGI) in the work-up of suspicious breast lesions compared with that of mammography (MG), breast ultrasound and MRI of the breast. METHODS Within a 15-month period, 67 patients with 92 breast lesions rated as Category IV or V according to the breast(More)
AIM The retrospective evaluation of correlations between semi-quantitative breast-specific gamma imaging (BSGI) and invasive ductal breast cancer (IDC) sub-types. MATERIALS AND METHODS The biopsy specimen of 50 histologically-proven IDCs were retrospectively evaluated concerning receptor status, human epidermal growth factor receptor 2 (HER2/Neu) status,(More)
OBJECTIVE Selective sacral neuromodulation may fail after fluoroscopically guided lead placement because of malpositioning. We implemented a new technique to attain precise lead placement. CONCLUSION CT-guided tined lead placement was successful in eight patients after 12-month follow-up. Especially in patients with an altered anatomy in the sacral(More)
Among all entities causing intestinal obstruction, internal hernias are rare. However, after retrocolic laparoscopic Roux-Y reconstruction, transmesocolic internal hernias may occur. The loss of mesenteric fat favors the formation of transmesocolic internal hernias, which are the most common type of acquired internal hernias. CT findings of segmental(More)
Fehllagen zentralvenöser Katheter (ZVK) können gravierende Folgen haben – z. B. toxische Effekte von Paravasaten, Blutungskomplikationen, Pneumothorax oder Perikardtamponade. Anhand des folgenden Falles stellen wir ein Untersuchungsprotokoll für die Computertomografie (CT) vor, das wichtige Fragen bei vermuteter ZVKFehllage beantwortet: 1. Liegt eine(More)
Hemodynamically stable patients with renal injury can be managed conservatively. Anatomy typically leads to physiologic confinement of urinomas or renal hematomas to the interfascial planes of the retroperitoneum. In the presented case there was unusual reperfusion 14 days after a successful embolization of a renal pseudoaneurysm, at this time 28 days after(More)
Blunt abdominal trauma can lead to mesenteric injuries, which are not an uncommon but often underestimated finding on the initial computed tomography (CT) scan. Only small mesenteric hematomas, which are shrinking in short-term follow-up CT examinations, do not require surgery. We present two cases where subtle mesenteric hematoma was one hint on the(More)
