Pott's Puffy tumor is a subperiosteal abscess of the anterior wall of the frontal sinus associated with underlying frontal bone osteomyelitis. It most commonly occurs as a complication of frontal sinusitis and presents with a fluctuant area of swelling over the forehead, accompanied by fever, headache, and rhinorrhea. Early diagnosis and treatment are crucial, as more than 50 % of cases of Pott's Puffy Tumor progress to result in intracranial pathology. This is a case of an adolescent male who presented to the emergency department with a "growing bump" on the top of his head and associated nasal congestion. Point-of-care ultrasound demonstrated a subdermal collection with an associated calvarial bone defect and an underlying collection communicating with the intracranial space. The patient was ultimately diagnosed with a calvarial Pott's Puffy Tumor and was found to have multiple subgaleal and epidural abscesses with an associated superior sagittal sinus thrombus. He required a craniotomy and a prolonged course of parenteral antibiotics. He has since recovered and is doing well.
