PURPOSE OF THE STUDY
Diaphyseal aneurysmal bone cyst is very rare. We report a case in a 20-year-old female.
PATIENT AND METHOD
The clinical signs developed rapidly, within one month. The lesion was first curetted and grafted with cortico-cancellous bone. Recurrence was observed 6 months later. Complete excision and reconstruction with a free fibular vascularized grafted enabled healing.
DISCUSSION
The pathogenesis of aneurysmal bone cysts is debated. We hypothesize that it is due to the opposed direction of periosteal and medullary blood circulation. This could explain the relative rarity of diaphyseal localizations compared with metaphyseal localizations.
研究目的
骨干动脉瘤样骨囊肿非常罕见。我们报告一例20岁女性病例。
患者与方法
临床症状在一个月内迅速出现。病变首先进行刮除并植入皮质松质骨。6个月后观察到复发。采用游离腓骨带血管蒂移植进行完整切除和重建实现了愈合。
讨论
动脉瘤样骨囊肿的发病机制存在争议。我们推测这是由于骨膜和骨髓血液循环方向相反所致。这可以解释骨干部位与干骺端部位相比相对罕见的原因。
