“…Der bei der PsA häufige Befall der Kiefer-, Sternoclavikular-und Manubriosternalgelenke und die Entesiopathien besonders am Achillessehnenund Plantaraponeurosenansatz müssen bei entsprechenden Symptomen gezielt untersucht werden [8]. Am einzelnen Gelenk können nach Dihlmann [9] auch bei der PsA arthritische Kollateral-Phänomene und arthritische Direktzeichen unterschieden werden.…”

“…Im Bereich des Kapselansatzes sieht man feinste (oft nur mit der Lupe erkennbare) Appositionen ("Protuberanzen"), die der Epiphyse kranzartig oder wie ein Wollkragen anliegen. Kleine unregelmäßige Proliferationen im Bereich von Erosionen verleihen der Oberfläche ein ausgefranstes Aussehen [9]. Eine subperiostale pathologische Knochenneubildung führt zur subchondralen Sklerose, .…”

Conventional radiography is still the standard method of imaging in PsA since it displays many joints at the same time, thereby allowing different types of joint involvement to be recognized. Moreover, thanks to the high resolution of radiography, bony changes in a single joint are depicted in a brilliant way. Several features of psoriatic arthritis allow the distinction from rheumatoid arthritis, including the frequent involvement of the distal interphalangeal joints, asymmetry of joint involvement, axial involvement of finger joints, oligoarticular involvement; however, symmetric polyarthritis is also possible. At the level of the single joint, there are signs of severe destructive changes potentially leading to mutilation and at the same time signs of periostal bone proliferation and ankylosis may be present. Bony proliferation and/or osteolysis are not restricted to the joint region but can affect also the total phalanx with bone apposition or concentric osteolysis which may lead to a complete disappearance of phalanxes. For purposes of quantification of radiographic changes scoring methods are used that were originally developed for rheumatoid arthritis. So far, there is only one validated scoring method that was specifically designed for PsA and that takes into account both features of PsA, damage as well as proliferation of bone. In contrast to conventional radiography, MRI and sonography are able to visualize inflammatory processes within the soft tissue (joint capsules, tendon sheaths, tendon insertions, etc.), allowing an estimation of disease activity. Scintigraphy is nonspecific and can only be used to detect clinically silent inflammatory spots. The relatively frequent spinal (axial) involvement is similar to that seen in ankylosing spondylitis. However, unilateral sacroiliitis, asymmetry of syndesmophytes and development of parsyndesmophytes may distinguish PsA from ankylosing spondylitis. While conventional radiography demonstrates the bony consequences of inflammation in the spine, MRI also shows the active inflammatory changes in sacroiliacal joints and vertebrae.

“…Werner et al [32] showed a correlation between cortical micro-channels and the occurrence of bone erosions in bare areas.Especially in early, preclinical or undifferentiated arthritis with small or no erosions, it is necessary to differentiate a true rheumatic erosion from the various forms of normal erosion-simulating concavities of the bony surface and therefor avoid false-positive statements [38,39]. Such so-called pseudoerosions [40] have been described to be smooth and well demarcated on radiographs, ultrasound, computed tomography (CT) and MRI [41]. The effect of misinterpreting a normal anatomic concavity as an erosion or vice versa may be estimated from the intra-and inter-reader variations of scoring systems and has been directly mentioned for the RAMRIS (rheumatoid arthritis MRI score) [42,43].…”

Rheumatoid arthritis is a chronic inflammatory disease characterized by the development of osseous and cartilaginous damage. The correct differentiation between a true erosion and other entities—then often called “pseudoerosions”—is essential to avoid misdiagnosing rheumatoid arthritis and to correctly interpret the progress of the disease. The aims of this systematic review were as follows: to create a definition and delineation of the term “pseudoerosion”, to point out morphological pitfalls in the interpretation of images, and to report on difficulties arising from choosing different imaging modalities. A systematic review on bone erosions in rheumatoid arthritis was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following search terms were applied in PubMed and Scopus: “rheumatoid arthritis”, “bone erosion”, “ultrasonography”, “radiography”, “computed tomography” and “magnetic resonance imaging”. Appropriate exclusion criteria were defined. The systematic review registration number is 138826. The search resulted ultimately in a final number of 25 papers. All indications for morphological pitfalls and difficulties utilizing imaging modalities were recorded and summarized. A pseudoerosion is more than just a negative definition of an erosion; it can be anatomic (e.g., a normal osseous concavity) or artefact-related (i.e., an artificial interruption of the calcified zones). It can be classified according to their configuration, shape, content, and can be described specifically with an anatomical term. “Calcified zone” is a term to describe the deep components of the subchondral, subligamentous and subtendinous bone, and may be applied for all non-cancellous borders of a bone, thus representing a third type of the bone matrix beside the cortical and the trabecular bone.
