Figure 1. (A). Orbit and brain MRI with contrast shows 5×0.8×4 cm of frontal scalp subgaleal rime enhancing fluid collection, showing subgaleal abscess (arrow head) with mild restricted diffusion within the frontal calvarium, compatible with early changes of osteomyelitis. Moderate fluid collection is shown in underlying frontal sinuses (arrows). (B) MRI brain and orbit shows fluid throughout maxillary sinuses, with mild mucosal thickening bilaterally (arrows). Fluid and mucosal thickening within ethmoid air cells is shown (arrow heads). The findings show acute and chronic sinusitis.
