  • - Takayasu arteritis (TAK) is a serious condition affecting large blood vessels, leading to complications like aneurysms and stenosis, and while treatment for older patients has shown promise with tocilizumab (TCZ), its effects in younger patients (under 12) are not yet clear.
  • - A case study of a 2-year-old girl with TAK type V revealed that her condition, which included aortic aneurysms and renal artery stenosis, improved significantly after being treated with intravenous TCZ alongside prednisolone and methotrexate.
  • - After 4 months on TCZ, imaging showed notable recovery in her vascular issues, suggesting TCZ is a potential effective treatment for inflammation, aneurys

13-cis-retinoic acid (13-cis-RA) treatment is used as a second-line treatment for residual or recurrent neuroblastoma. However, determining the duration of 13-cis-RA treatment for residual and recurrent neuroblastoma can be a problem because it is difficult to evaluate the effectiveness of the treatment.We performed 13-cis-RA treatment to remove residual active neuroblastoma cells in an 8-year-old boy with stage 4 neuroblastoma that developed from a left sympathetic ganglion and had been treated with chemotherapy, surgery, autologous peripheral blood stem-cell transplantation, and radiotherapy.

A woman was referred to our institution with an ultrasound (US) suggestive of right-sided heart in fetus at 34 weeks' gestation. Magnetic resonance (MR) imaging revealed right-sided heart, small right hemithorax, and completely absent right main bronchus and right pulmonary artery. From our experience with this case, we point out 5 important MR imaging findings needed for prenatal diagnosis of pulmonary agenesis.
