Exploring the intersection of tuberous sclerosis and precocious puberty unveiled by hematocolpos.

We present the case of a 6-year-old girl who initially presented with acute pelvic pain, ultimately diagnosed with imperforate hymen leading to hematocolpos. Further investigation revealed additional clinical features including academic struggles, mood swings, and cutaneous findings, prompting consideration of a neurocutaneous syndrome. Magnetic Resonance Imaging (MRI) revealed features consistent with tuberous sclerosis complex (TSC), including radial migration lines in the subcortical white matter and an incidental arachnoid cyst. Notably, this case exhibited a unique presentation with absence of typical TSC findings such as subependymal nodules or cortical tubers. Additionally, precocious puberty, rarely associated with TSC, was observed, suggesting a potential link between hypothalamic lesions and hormonal imbalance. This case underscores the importance of comprehensive evaluation in pediatric patients presenting with seemingly unrelated symptoms, as it may unveil underlying conditions necessitating tailored management strategies.
