Femur ve iskiyumda eşzamanlı basit kemik kistleri

Bu yazıda, sağ femurun proksimal üçte birlik bölümünde ve aynı tarafta iskiyum ramusta eşzamanlı olarak basit kemik kisti (BKK) saptanan 30 yaşında erkek hasta sunuldu. Her iki lezyon için de ince iğne aspirasyon biyopsisi yapıldı. Femurdaki lezyondan lokal anestezi altında biyopsinin başarılı olamaması nedeniyle açık biyopsi uygulandı ve biyopsi sonucu tanı BKK olarak kondu. İskiyumdan alınan biyopsi ise tanı için yeterli olamadı. Her iki lezyondan alınan biyopsilerde başka benign ya da malign patolojiye rastlanmadı. Femoral lezyon, büyük olması nedeniyle intralezyonal eksizyon-küretaj, kemik greftleme ve patolojik kırık riskine karşı uzun gama kilitli intramedüller çivi ile tedavi edildi. İskiyumdaki lezyona ise bir girişimde bulunulmadı ve konservatif olarak izlendi. Hastada ameliyat sonrası üç yıl boyunca semptom ve komplikasyon görülmedi. Sunulan olgu, hem uzun kemikte (femur) hem de düz kemikte (iskiyum ramus) eşzamanlı BKK bildirilen ilk erişkin hastadır.

Femur ve iskiyumda eşzamanlı basit kemik kistleri

We report a 30-year-old male patient with two unicameral bone cysts (UBC) simultaneously located in the proximal third of the right femur and ipsilateral ischium ramus, respectively. Fine needle biopsies were attempted for both lesions. Biopsy of the femoral lesion under local anesthesia was unsuccessful, so an open biopsy was performed which confirmed the diagnosis of UBC. Biopsy of the ischial lesion was not sufficient for diagnosis. Cytological examination of both specimens showed no other benign or malignant pathology. The femoral lesion was treated with intralesional (due to its large size) excisiocurettage, bone grafting, and the introduction of a long gamma locking intramedullary nail to prevent the occurrence of a pathological fracture. The ischial lesion was left untreated and followed conservatively. The patient was free of any symptoms and complications three years postoperatively. This is the first report of an adult patient with UBCs simultaneously located both in a long tubular bone (femur) and a flat bone (ischium ramus).
