Case in brief
A 2-year-old boy presented with scalp swelling, leading to the diagnosis of Langerhans cell histiocytosis (LCH) with dural involvement. Imaging studies revealed features that mimicked meningioma or inflammatory pachymeningitis. The use of combined MRI and FDG PET imaging allowed for detailed structural assessment and evaluation of metabolic activity, aiding in the management of this rare manifestation of LCH.
What made this case unusual
Dural involvement in LCH is a rare presentation, often resembling other conditions such as meningioma.
Diagnostic / clinical pearl
Clinicians should consider LCH in pediatric patients with dural lesions that present similarly to meningioma or inflammatory conditions.
Why it matters
This case highlights the importance of multimodal imaging in differentiating LCH from other dural pathologies, which can impact treatment decisions.
