Neonatal renal venous thrombosis: sequential ultrasonic appearances.
The ultrasonic appearances of three cases of renal venous thrombosis are shown. Initially the kidney is enlarged, echogenic and shows echogenic streaking that has a vascular or perivascular distribution. Subsequently thrombosis of renal veins or the inferior vena cava may be demonstrated and ultimately the kidney may recover or atrophy. The ultrasonic appearances will depend on the severity of the thrombosis and the stage at which the examination is performed.
Skeletal complications of type I Gaucher disease: the magnetic resonance features.
Abnormalities on magnetic resonance imaging (MRI) are reported in six individuals with various skeletal complications of type I Gaucher disease. The changes were a nonhomogeneous reduction in both T1 and T2 marrow signals with increased T2 signals during avascular episodes. MRI proved an excellent technique for the assessment of bone marrow changes in Type I Gaucher disease and for assessing avascular complications. It was not able to differentiate between pseudo-osteomyelitis and pyogenic osteomyelitis without clinical correlation. The problems studied included the extent of intramedullary Gaucher cell infiltration, avascular necrosis of femoral heads, assessment of bone pain from pseudo-osteomyelitis and the relationship of skeletal disease to splenectomy.
