Background: Multiple evanescent white dot syndrome (MEWDS) is usually acute and self-limited, whereas multifocal choroiditis (MFC)/punctate inner choroidopathy (PIC) is relapsing; overlap can obscure early diagnosis and requires longitudinal multimodal imaging. Methods: We report a 4-year follow-up of a 31-year-old woman with fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA), and spectral-domain optical coherence tomography (SD-OCT), plus a systemic/neurologic/rheumatologic work-up. Treatment included intravenous methylprednisolone for presumed optic neuritis, followed by topical, periocular, intravitreal, and systemic corticosteroids, later escalated to adalimumab and an intravitreal dexamethasone implant. Because foveal granularity could not be documented, baseline was termed "MEWDS-like". Diagnostic labelling was benchmarked against Standardization of Uveitis Nomenclature (SUN) criteria, and choroidal neovascularization (CNV) was assessed at each relapse by OCT and FA. Results: The right eye initially showed a MEWDS-like pattern with wreath-like FA lesions and disc leakage, hyperautofluorescent FAF lesions, focal ellipsoid zone disruption on SD-OCT, and multifocal ICGA hypofluorescent spots. A relapse at 6 months with peripapillary inflammatory foci and recurrent cystoid macular edema supported reclassification to a unilateral MFC/PIC-spectrum phenotype. At 2 years, the fellow eye developed mild vitritis, peripapillary hyperautofluorescence, peripapillary/arcade leakage on FA, delayed peripapillary filling on ICGA, and cystoid macular edema, establishing sequential bilateral MFC; no CNV developed and anti-vascular endothelial growth factor (anti-VEGF) therapy was not required. Complications included steroid-induced ocular hypertension and cataract surgery. Conclusions: The purpose of this report is to highlight longitudinal imaging "red flags" that supported reclassification from a MEWDS-like phenotype to a sequential bilateral MFC/PIC-spectrum disease.
