ABSTRACT

Clinical data of one patient diagnosed with kaposiform hemangioendothelioma (KHE) in the spinal canal and mediastinum at the Children′s Hospital, Zhejiang University School of Medicine in October 2022 were retrospectively analyzed.Additionally, a literature review on mediastinal KHE was performed to summarize prior clinical characteristics and treatments.The patient, a 25-day-old boy, presented with refractory thrombocytopenia.Multiple chest radiographs suggested significant widening of the mediastinum and atypical atelectasis in the left upper lung, and enhanced chest CT and magnetic resonance imaging suggested KHE.After cocktail therapy with Prednisolone, Vincristine and Sirolimus, platelets increased to normal, and coagulation function improved.After 3 months of follow-up, hematologic parameters were stable, the mass became smaller, and no side effects occurred.
