Zusammenfassung
Die solitäre Knochenzyste des Beckens stellt eine seltene Läsion dar. Sie ist bei ausreichendem Biopsie- bzw. Operationsmaterial einfach zu diagnostizieren. Kalzifizierende Formen bereiten differenzialdiagnostisch häufig Schwierigkeiten in der Diagnosestellung. Radiologisch ist die Läsion bei großen Defekten im Becken nicht sicher zu diagnostizieren. Eine Biopsie ist die Methode der Wahl für die endgültige Diagnose. Am späteren Operations- bzw. Kürettagematerial ist die Diagnose zu überprüfen. Knochentumoren des Beckens sind in der differenzialdiagnostischen Eingrenzung in Betracht zu ziehen. Gerade große „zystische“ Läsionen des Beckens bedürfen der kritischen Überprüfung einer pathohistologischen Diagnose, um Fehlinterpretationen zu vermeiden. Die Folgen für die Patienten sind im Einzelfall bezüglich Lebensqualität und Lebenserwartung gravierend. Mehr denn je ist an der Forderung nach einer interdisziplinären Zusammenarbeit für die korrekte Diagnostik und Therapie der Knochentumoren festzuhalten.
Abstract
Solitary bone cyst of the pelvis is a rare lesion. The diagnosis is relatively simple providing sufficient material is accumulated during biopsy or surgery. Calcifying forms often cause difficulties in terms of differential diagnosis. Radiographic imaging can be complex when examining large lesions of the pelvis. Biopsy is the method of choice for definitive diagnosis, which should be verified against material gathered surgically or during curettage.
Bone tumors of the pelvis have to be considered in the differential diagnosis of the lesion. Large cystic lesions of the pelvis in particular are to be reviewed pathohistologically to avoid false diagnosis. The consequences for the patient in terms of quality of life and life expectancy can be serious. The need for interdisciplinary cooperation is greater than ever to ensure correct diagnosis and therapy of bone lesions.
