Figure 1: Axial magnetic resonance imaging brain showed an area of restricted diffusion in the scalp (white arrow a) which is an encapsulated collection in extracalvarial soft tissue in right frontal region measuring about 37 mm with focal areas of altered signal intensity of right frontal marrow. There is an associated subdural collection in the frontal region with associated meningeal enhancement (postcontrast axial magnetic resonance T1-weighted images white arrow b and c) along right fronto temporal dura flax cerebri cortical sulci and the frontal region (coronal magnetic resonance imaging T1-weighted images white arrow d). The features appeared even more distinct on the magnetic resonance imaging postcontrast fluid-attenuated inversion recovery images which showed distinct enhancement of the scalp collection (white arrow e) and the meninges (white arrow f). The magnetic resonance imaging features are suggestive of scalp abscess with bone osteomyelitis and intracranial spread of abscess with focal patchy leptomeningitis
