Cephalohaematoma: Not always a benign bump.

In case 1, we hypothesise that the cephalohaematoma developed into subgaleal abscess with bacterial seeding from the antecedent urinary tract infection. The blood culture was also negative, white cell count (WCC) was 5.7 × 10 SP 9 sp /L and C-reactive protein (CRP) was 77.4 mg/L. Cranial ultrasound showed a lentiform 8.9 × 6.9 cm collection consistent with a large uncomplicated cephalohaematoma. If the cephalohaematoma does show signs of localised infection with possible extension, appropriate imaging with high diagnostic yield for osteomyelitis (CT or magnetic resonance imaging) is warranted with consideration given to debridement.
