Multiple localized small cortical holes superimposed over the marrow.

Case Discussion

A pseudopermeative process in bone has multiple small cortical holes that are then superimposed over the marrow, giving a similar appearance to a permeative process. Most common pathologies that manifest with pseudopermeative appearance (and mimic permeative lesions) include: disuse (aggressive) osteopeniahemangioma and radiation.
