One month old male with large soft tissue mass on right head and history of sepsis. Examination of intracranial content demonstrates normal morphology and density of brain parenchyma. Cortical sulci, ventricular system and all CSF cisterns remain within normal limits. There is complete opacification of the left middle ear cavity and mastoid air cells. These findings represent otitis media. Right mastoid air cells and middle ear cavity cavity are well pneumatized and are unremarkable.Bony density of calvarium demonstrates some periosteal thickening in the right posterior parietal in region of large soft tissue abnormality of the scalp that was noted on clinical exam. No definitive evidence of abnormal enhancement is detected. No definitive evidence of any cavity formation is present. Although possibility of infection cannot be entirely ruled out possibility an old sub periosteal hemorrhage should also be considered. No definitive evidence of any edematous changes of the adjacent subcutaneous fat is detected. There is no evidence of any abnormality of the inner table of the skull or the marrow space. Further evaluation with an infused MRI is recommended.
