Publication Castleman's disease: Unilateral cervical involvement and imaging findings a case report(Sage Publications Inc, 2007-06-01) Atahan, S.; Hakyemez, B.; Doğan, Nurullah; HAKYEMEZ, BAHATTİN; Topal, N. B.; BOLCA TOPAL, NAİLE; Parlak, M.; PARLAK, MÜFİT; Bursa Uludağ Üniversitesi/Tıp Fakültesi; 0000-0003-1455-6918; AAI-2327-2021; AAI-2318-2021; AAG-8521-2021Castleman's disease is an idiopathic lymphoproliferative disorder characterized by massive enlargement of lymph nodes. It may have a unifocal or multifocal presentation; the mediastinum is the most common site (70%). Patients with cervical disease usually have unifocal involvement (90%). The main problem posed by cervical Castleman's disease is that it should be considered in the differential diagnosis of cervical tumors. This report describes a patient who had unifocal Castleman's disease on the left side of the neck, and discusses the differential diagnosis with findings on magnetic resonance imaging, computed tomography and ultrasonography.Publication Effectiveness of percutaneous vertebroplasty in cases of vertebral metastases(Elsevier Masson, 2015-11-01) Nas, O. F.; İnecikli, M. F.; Kaçar, E.; Büyükkaya, R.; Özkaya, G.; Aydın, O.; Erdoğan, C.; Hakyemez, B.; NAS, ÖMER FATİH; ÖZKAYA, GÜVEN; Erdoğan, Cüneyt; HAKYEMEZ, BAHATTİN; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0003-0297-846X; 0000-0002-3425-0740; AAG-8561-2021; COE-1124-2022; A-4421-2016; AAI-2318-2021Purpose and objectives: To assess the effectiveness of percutaneous vertebroplasty (PV) in patients with vertebral collapse due to metastases.Materials and methods: PV procedures performed on 95 vertebras in 52 patients with primary malignancy were retrospectively evaluated. Vertebral metastases, primary malignancies of the patients, pain before and after PV on a visual analogue scale (VAS), amount of polymethylmethacrylate (PMMA) cement applied to the vertebral body during PV, PMMA cement leakage and vertebral approaches were evaluated.Results: VAS scores of 43 patients (in total 79 vertebras) were evaluated. Median VAS scores of patients declined from 8 (4-10) before PV to 3 (0-7) within one day after the procedure, to 2 (0-9) one week after the procedure and eventually to 2 (0-9) 3 months after the procedure (p < 0.001). PMMA amount applied to the vertebral body during PV varied between 1.5-9 mL (average +/- SD 4.91 +/- 1.61). There was no significant statistical correlation between PMMA amounts and VAS scores within one day after, 1 week after and 3 months after the PV procedure (p > 0.05).Conclusion: PV is a simple, effective, reliable, easy to perform and minimally invasive procedure in patients with painful vertebral metastases.
