Doppler sonographic diagnosis of respiration-dependent reversed flow in the hilar splenic vein.

We describe respiration-dependent reversed flow in the splenic vein detected by color Doppler sonography in 2 patients. In case 1, gray-scale sonography in a patient with liver cirrhosis and abdominal pain showed a hyperechoic, thickened colonic segment and diverticula, with increased echogenicity around the diseased colon. The liver was small, with a nodular surface and coarse echotexture. Doppler sonography of the portal and splenic veins showed a constant hepatopetal flow while the patient held her breath in midinspiration and a brief, transient color change restricted to the hilar splenic veins when the patient took a deep breath. In case 2, abdominal sonography in a patient with pneumonia and right-sided abdominal pain showed mural thickening of the appendix and left-sided pneumonic infiltration. The liver size and texture were normal. Color Doppler sonography of the portal and splenic veins showed a constant hepatopetal flow while the patient held his breath in midinspiration and a transient reversal of flow restricted to the splenic veins when the patient took a deep breath. Although the cause of this flow pattern is unclear, increased intra-abdominal pressure is a possible explanation.

[Incipient spinal cord compression syndrome due to a herniation of calcified intervertebral disk in a young girl].

Intervertebral disc calcification in childhood is rare. Calcifications are discovered by occasion during routine examinations of healthy children or evoke symptoms like neck and shoulder pain or discrete neurological symptoms. The prognosis of nearly all patients is excellent. We report on a 11-year-old girl, who suffered from acute pain in the neck and the left shoulder with increasing paresthesias of her left extremities which led to hospitalisation. Intervertebral disc calcifications were found between several cervical and thoracic vertebra. The only paraclinical finding was an elevated erythrocyte sedimentation rate. After 12 days of conservative and analgetic treatment the clinical condition deteriorated with acute worsening of the neck pain. The MRI revealed a posterior herniation of a calcified disc between the lower cervical spine with spinal cord compression. Immediate neurosurgical intervention led to decompression and disappearance of the symptoms. After 14 months the clinically healthy child only showed the persistence of one intervertebral disc calcification and a complete resolution of the former findings.
