Show Evidence

We describe a 49-year-old woman who presented with continuous bilateral lumbago. As the patient's ultrasonography manifestations were very similar to those of bilateral hydronephrosis, we performed retrograde pyelography and ureteroscopy. However, apart from slight left ureteropelvic junction obstruction, there was no hydronephrosis. Since malignant disease could not be completely denied, computed tomography-guided biopsy was performed. However, the tissue did not show evidence of malignancy. As the patient continued to have lumbago, we measured serum IgG4 levels because of suspicion of retroperitoneal fibrosis secondary to IgG4-related disease, which proved to be high. Further, immunostaining of the renal pelvic biopsy samples showed IgG4-positive cells. Therefore, diagnosing IgG4-related retroperitoneal fibrosis, we administered corticosteroids. The patient responded favorably to the drug, with gradual regression of the lesion.

SummaryVascular malformations are structural abnormalities, errors of vascular morphogenesis, which can be localized in all parts of the vascular system. All vascular malformations by definition, are present at birth and grow proportionately with the child; their volume can change. In contrast to the haemangiomas, which only proliferate from the endothelial cells the division in stages is of clinical importance. Vascular malformations are divided from the part of vascular system, which is affected.In principle the techniques of laser application in congenital vascular tumours like haemangiomas and in vascular malformations are similar, but the aim is different. In tumours the aim is to induce regression, in vascular malformations the aim is to destroy the pathologic vascular structure because there is no spontaneous regression. This means that the parameters for treatment of vascular malformations must be more aggressive than for vascular tumours.
