Patient: The baby was born with a large wine discoloration on the right leg. The erythema on the outer thigh was larger and thicker, continuing below the knee, while the lower leg was florid and lighter in color compared to the erythema on the thigh. A blue blood vessel cluster was faintly visible under the discoloration on the outer thigh up to the top of the dorsum of the foot. The color of the erythema became lighter when the right leg was elevated or when the erythema was pressed. The ultrasound of both legs showed no problems with the large arteries and veins. Now the problem is that the right leg is about 1 cm thinner than the left leg from the erythema, and there is a tendency for the difference in thickness between the two legs to slowly increase. Is this a problem of low flow rate caused by the cavernous hemangioma, and is there any way to avoid the problem of the gap between the two legs becoming bigger? In addition, I would like to ask how old the baby can be for MRI examination. The difference in thickness between the two legs cannot be ruled out as a result of deep hemangioma, which can be clarified by MRI. Chloral hydrate can be given orally or by enema. Patient: Can there be any measures to promote blood circulation in the legs due to insufficient blood supply caused by this deep hemangioma? Li Zhanglin, Department of Pediatric Oncology, Tianjin Cancer Hospital: From the literature and our clinical observation, some children with limb hemangioma may show hypertrophy of the affected limb due to richer local blood circulation than the healthy side. It is suggested that it is not necessary to give treatment before checking MRI to clarify the scope of tumor.
