Tissue Expander for Pediatric Scalp Reconstruction Complicated by Fungal Infection With Aspergillus terreus.

Background: Tissue expansion is an effective option for soft tissue reconstruction of the scalp in the pediatric population. Unfortunately, this approach carries a high risk of such complications as infection and expander exposure. While bacterial infection of alloplastic materials is most frequent, when fungal infections occur, the outcomes can be devastating. Purpose: To inform the management of fungal tissue expander infections, this report describes a case of expander-based scalp reconstruction complicated by Methods: A patient who had blunt-force head trauma presented with soft tissue injury and depressed skull fracture requiring emergent craniectomy. After stabilization, a paucity of soft tissue coverage required further surgical intervention before reconstructive cranioplasty. Six months after her injury, two remote port subgaleal tissue expanders were placed. Subsequently, purulent drainage developed from the surgical incision. Results: Infection resulted in expander exposure requiring device removal and treatment with clindamycin and ceftazidime while awaiting culture results. Intraoperative cultures were positive for Conclusions: Though tissue expansion remains a viable reconstructive option, fungal infection can be disastrous, requiring systemic antifungal therapy, surgical debridement, and expander removal.
