Case: Cavernous hemangioma, an uncommon benign vascular lesion, can affect different joints. It generally presents as atraumatic swelling over the joint with normal radiographic findings. We present a case of a healthy 5-year-old girl with chronic knee pain over the anteromedial aspect following minor trauma. Conclusion: The patient underwent all baseline blood investigations and plain radiograph of her knee, all of which were normal. Magnetic resonance imaging showed hemangioma. Surgical excision was performed and histological studies confirmed a cavernous hemangioma. Delayed diagnosis may increase the risk of invading and damaging the joint resulting in further morbidities.
