periosteal reaction

Fett im
Frakturkallus bei distaler Radiusfraktur. Ca. 2 Monate nach der ursprünglichen Fraktur fanden sich in dem Bereich der Periostreaktion regionale, scharf begrenzte Lysezonen. Die zu diesem Zeitpunkt angefertigte MRT zeigte in der periostalen Knochenneubildung an dieser Stelle fetthaltiges Material. Dies ist als seltene, transiente Erscheinung im Rahmen der Frakturheilung (insbesondere bei Kindern und insbesondere am distalen Radius) zu sehen. Röntgenbilder vom Unfalldatum, nach 2 Monaten, nach ca. 1,5 Jahren. MRT T1cor, T2m STIR, T1 FS ax, T1 FS sag.

Periosteal reaction, also known as periostitis or periosteitis, is a nonspecific radiographic finding that indicates periosteal irritation. Periosteal reactions may be broadly characterized as benign or aggressive, or more specifically categorized by pattern.

Classification

Benign versus aggressive

Periosteal reaction may be classified as benign or aggressive (note: not benign and malignant) based on the time course of the initiating process.

Benign periosteal reaction

Low-grade chronic irritation allows time for the formation of normal or near-normal cortex. The cortex will be thick and dense and have a wavy or uniform appearance.

Benign periosteal reactions can be seen in callus formation in a fracture or with slowly growing tumors.

Aggressive periosteal reaction

Rapid irritative processes do not allow the periosteum time to lay down and consolidate new bone to form normal cortex. The cortex may appear lamellated, amorphous, or sunburst-like.

Aggressive periosteal reactions can not only be seen with malignant tumors, but also with more benign processes like infection, eosinophilic granuloma (Langerhans cell histiocytosis), aneurysmal bone cyst, osteoid osteoma, hemophilia , and trauma.

Morphological classification of periosteal reactions

More specific classification of periosteal reactions can be made to narrow the differential diagnosis.
