Subperiosteal hematoma (SPH) is a rare complication of neurofibromatosis type 1 (NF-1) which can be presented spontaneously or after a minor trauma a painful or painless growing lesion.
Here, we presented a 10-year-old boy, a known case of NF-1, who presented with a painless growing leg lesion. The bony wall cystic lesion was suggested based on radiologic and pathologic investigation. During the operation, an SPH was detected and excised completely.
Consistent with previous reports, our case of subperiosteal hematoma in an NF-1 patient predominantly presented with well-established subperiosteal bone proliferation on plain radiographs, with the hematoma most commonly affecting the tibia.
The SPH in NF-1 and differentiating it from a malignant transformation should be considered for the rapidly enlarging bony mass.
骨膜下血肿（SPH）是1型神经纤维瘤病（NF-1）的一种罕见并发症，可自发出现或在轻微创伤后出现，表现为疼痛或无痛的生长性病变。
在此，我们报告一名10岁男孩，他是已知的NF-1患者，出现了腿部无痛性生长性病变。根据放射学和病理学检查提示为骨壁囊性病变。手术中，发现并完全切除了一个骨膜下血肿。
与先前的报告一致，我们的NF-1患者骨膜下血肿病例在X线平片上主要表现为已形成的骨膜下骨增生，血肿最常累及胫骨。
对于迅速增大的骨质肿块，应考虑NF-1中的骨膜下血肿并将其与恶性转化相鉴别。
