Management of choroidal solitary fibrous tumor with extraocular extension and subsequent postoperative rhegmatogenous retinal detachment.

Purpose: Extraocular extension of a solitary fibrous tumor (SFT) in the choroid is rare, and few reports describe cases in which the eye is preserved and monitored postoperatively. This report details the management of an SFT with extraocular invasion complicated by postoperative rhegmatogenous retinal detachment (RRD). Observations: A 57-year-old woman presented with painless eyelid swelling. Imaging revealed a choroidal mass infiltrating the extraocular tissues. Partial surgical excision was performed after the patient refused enucleation without a tissue diagnosis. Histopathological and immunohistochemical analyses confirmed the diagnosis of SFT. Postoperatively, the patient developed RRD due to acute posterior vitreous detachment. Pars plana vitrectomy was successfully performed to address the RRD. Despite residual tumor within the eye and extraocularly, no tumor progression was observed during six months of follow-up. Visual function remained stable. Conclusions/importance: This case highlights the clinical challenges posed by choroidal SFTs with extraocular extension. This case underscores the importance of vigilant postoperative monitoring for complications such as RRD. Regular follow-up is crucial to assess tumor stability, manage potential complications, and maintain visual function in patients with residual disease.
