Pott's puffy tumour is a specific clinical finding related to infections of the skull.
Defining Pott's Puffy Tumour
Pott's puffy tumour is defined as a subperiosteal abscess. This abscess occurs on the external surface of the skull, beneath the periosteum (the membrane covering the bone). It is specifically associated with underlying osteomyelitis, which is an infection of the bone itself. The infection typically affects the frontal bone of the skull.
Key Characteristics
- Location: Scalp, specifically over the frontal bone.
- Pathology: Involves both bone infection (osteomyelitis) and a collection of pus (subperiosteal abscess).
- Appearance: Presents as a soft, fluctuant swelling on the scalp, often described as "puffy".
Differential Diagnosis Consideration
While other scalp conditions exist, Pott's puffy tumour is distinct due to the combination of the soft swelling and the underlying bone infection, most commonly originating from sinusitis or direct trauma.
Therefore, the correct description of Pott's puffy tumour is a subperiosteal abscess associated with osteomyelitis of the frontal bone.
