Fokal-noduläre Hyperplasie der Leber bei 930 Patienten
Analysis of 930 patients with focal nodular hyperplasia of the liver (FNH), including 23 seen by the authors, showed the following results: 82.2% of patients were female, 37.8% of these had taken female steroidal hormones. There was no preference for a particular lobe of the liver. 57.7% of FNH were subcapsular, 33.7% were intrahepatic and 8.8% were pedunculated. Average size was 5.9 cm, 80.8% of the patients were asymptomatic. In 93.5% (115 out of 123) a space-occupying lesion in the liver could be demonstrated by sonography. In 13%, second or multiple tumours were missed by sonography. CT without enhancement demonstrated FNH in 90.4% (94 out of 104 patients). A rapid, marked increase in d…
Pneumatoceles and pneumothoraces complicating staphylococcal pneumonia: treatment by synchronous independent lung ventilation.
A 54 year old man with a staphylococcal sepsis developed staphylococcal pneumonia complicated by multiple pneumatoceles and bilateral tension pneumothoraces caused by bronchopleural fistulae. Excessive enlargement of the right sided pneumatoceles and a tension pneumothorax not improved by drainage led to mediastinal shift and compression of the right lung. Reversal of the mediastinal shift and closure of the bronchopleural fistulae was achieved by assisted independent lung ventilation.
Farbcodierte Dopplersonographie (FD-Sonographie) primärer und sekundärer Lebertumoren
50 Patients with 78 focal liver lesions were examined via colour-coded Doppler system to study the vascularity of metastatic lesions and primary benign and malignant liver tumours. According to the amount of detectable colour Doppler signals, tumour vascularity was graded into 4 types. Metastases (n = 40) and cavernous haemangiomas (n = 12) seemed to be avascular with no evidence of increased vascularity (Type I/II). Conversely primary liver cancer (PLCA) (n = 7) and focal nodular hyperplasia (FNH) (n = 16) mainly produced arterial Doppler signals within the tumour (Type III/IV). AV shunts and partial portal vein thrombosis could be demonstrated in PLCA. Doppler colour flow imaging for dete…
