Osteochondrome und andere knorpelbildende benigne Tumoren der Wirbelsäule
Osteochondroma and benign chondrogenic tumors of the spineZusammenfassung
Unter den seltenen Primärtumoren des Skelettsystems zählen die chondrogenen zu den am häufigsten auftretenden. Innerhalb des chondroiden Grundmusters, zeigt sich eine große Bandbreite an radiomorphologischen und histopathologischen Erscheinungsformen mit variierender tumor-biologischer Aktivität. An der Wirbelsäule treten diese Tumoren deutlich seltener auf und klinisch stehen Schmerzen im Vordergrund. Aufgrund ihrer oft dorsalen Lokalisation sind neurologische Defizite nicht selten. CT und MRT sind maßgeblich für die bildgebende Diagnostik. Für das Management gilt das Prinzip der interdisziplinären Entscheidungsfindung und Therapie nach abgeschlossener Diagnostik, die eine suffiziente Biopsie einschließt. Entsprechend der Enneking Klassifikation der Tumoren sind intraläsionale und aggressive Resektionen in Abhängigkeit der zu Grunde liegenden, oft heterogenen tumor-biologischen Aktivität möglich. Entsprechend different sind Lokalrezidiv- und auch sekundäre Entartungsraten. Aufgrund ihres seltenen Auftretens, der notwendigen Diagnostik und der teils komplexen Therapie wird eine Zuweisung an ein spinal tumor-chirurgisches Referenzzentrum mit angeschlossener Infrastruktur empfohlen. Der folgende Artikel soll die Charakteristika, Diagnostik und Therapie benigner chondrogener Primärtumoren der Wirbelsäule aufzeigen und beschreibt exemplarisch Osteochondrome, Enchondrome, Chondro-myxoidfibrome und Chondroblastome der Wirbelsäule.
Abstract
Among primary tumors of the skeletal system, lesions with chondrogenic origin are most frequent. All present with a cartilaginous pattern, broadly varying in radiomorphologic and histopahtological characteristics as well as biological activity. They rarely appear at the spine, clinically presenting with local pain and - based on their often posterior localisation - with neurological deficits. CT- and MRI- scans are essential imaging tools. Following a complete diagnsotic work-up, that includes sufficient biospy, multidisciplinary decision-making is mandatory. Depending on the often heterogeneous biological activity and in accordance to the Enneking staging system, intralesional and aggressive resections are adequate in order to treat this lesions. Likewise, local recurrence and malignant transformation rates are differing. Due to the incidences, necessary diagnostic steps and propability for complex treatment regimens, admission to spinal tumor centers with affiliated oncological networks has to be recommended. This manuscript presents charactersitics, diagnostics and therapy of benign chondrogenic tumors with an examplary characterisation of osteochondroma, enchondroma, chondromyxoid fibroma and chondroblastoma.
