Diffusion-Weighted Mri in the Diagnosis of Intracranial Hematomas
(2013) Şanli, D.; Ünal, O.; Bora, A.; Beyazal, M.; Yavuz, A.; Avcu, S.
To determinate the diagnostic value of diffusion-weighted MR imaging (DWI) in intracerebral hematomas, epidural hematomas, subdural hematomas, and subarachnoid hemorrhage, and to assess the contribution of diffusion signal characteristics in the differentiation of hematoma stages. In this prospective study, consecutive 67 patients (range: 3-89 years), 35 (18 men 17 women) with intracerebral hematoma, 18 (10 men 8 women) with subdural hematoma, 2 (1 man 1 woman) with epidural hematoma, and 12 (5 men 7 women) with subarachnoid hemorrhage on conventional MRI sequences constituted the case group and were evaluated with DWI. Intracerebral, subdural and epidural hematomas detected on conventional MR sequences were also shown on DWI. But none of the cases with subarachnoid hemorrhage was demonstrated on DWI. All intracranial hematomas detected on DWI except from chronic stage subdural hematomas showed similar signal intensity characteristics on DWI and T2WI, but were hypointense on ADC maps. All intracerebral, subdural and epidural hematomas seen on conventional MR sequences could be detected by DWI. On the contrary, DWI was not an effective imaging method for detecting subarachnoid hemorrhages. Using DWI alone for detecting the stages of hemorrhages can provide only additional information in subdural and intracerebral hematomas, and it is unable to give definite results, and the lesions should be evaluated by the correlation with other conventional MRI sequences.
Endovenous Laser Ablation Treatment With 980 Nm Diode Laser for Saphenous Vein Insufficiency: 6 Months Follow Up Results
(Assoc Royal Soc Scientifiques Medicales Belges, 2014) Beyazal, M.; Avcu, S.; Ozen, O.; Yavuz, A.; Bora, A.; Unal, O.
Objective: Superficial venous insufficiency is a common problem associated with varicose veins which, if untreated, may progress to venous ulceration. Endovenous laser ablation (EVLA) is a new, minimally invasive method for management of superficial venous insufficiency and varicose veins. The aim of this study was to demonstrate the effectiveness of 980 nm EVLA for treatment of symptomatic saphenous venous insufficiency and to present its early outcomes. Methods: Thirty-eight great saphenous veins and 5 small saphenous veins in 40 patients with saphenofemoral reflux were treated with 980 nm diode endovenous laser equipment. The diameter and length of the vein treated, total laser energy and energy density (Joules/cm) delivered were recorded. To determine the severity of the venous disease Venous Clinical Severity Score (VCSS) and Visual Analogue Scale (VAS) were used. Patients were followed up for 6 months after the procedure. Complications were recorded prospectively. Results: Forty-three saphenous veins in 40 patients were treated. The mean age of the patients was 39.9 (range 2172) years. The mean diameter and length of the veins were 4.9 mm (range, 3.5 to 8.5 mm) and 30.2 cm (range, 16 to 50 cm), respectively. At 6 months follow-up, total occlusion rate was 95.4% (41/43), and recanalization rate was 4.6%. Significant decrease was observed for VCSS and VAS scores after the procedure. No major complication was detected. Conclusion: EVLA treatment for superficial venous insufficiency is safe and can be carried out under local anaesthesia in an outpatient setting with good patient satisfaction and low complication rates.
A Rare Case That Can Be Diagnosed With Prenatal Ultrasound: Fryns Syndrome
(Yuzuncu Yil Universitesi Tip Fakultesi, 2015) Çeliker, F.B.; Ceylan, N.; Turan, A.; Beyazal, M.
Fryns syndrome is a syndrome that is accompanied by multiple congenital anomalies, with extremely high mortality, showing autosomal recessive inheritance and often leaves severe mental retardation on those who survive. Abnormal facial appearance, distant faded nipples, small rib cage, distal extremity and nail hypoplasia, pulmonary hypoplasia and diaphragmatic hernia are among major criteria for the diagnosis. Later, cardiovascular, genitourinary, central nervous system and skeletal system anomalies have been identified. Here, we presented Fryns syndrome case which has been diagnosed by prenatal ultrasound, and of which the diagnosis has been confirmed by physical examination and ultrasound at the postnatal period. © 2015, Yuzuncu Yil Universitesi Tip Fakultesi.

Solitary Melanoma of the Central Nervous System: Case Report
(Lippincott Williams and Wilkins, 2015) Beyazal, M.; Yavuz, A.; Kiymaz, N.; Yilmaz, D.
Primary melanoma of the central nervous system (CNS) is a rare entity, thus the diagnostic and therapeutic experience is based on a limited number of published cases. The diagnostic dilemma of solitary CNS melanoma is whether it is primary. Primary CNS malignant melanoma has more favorable prognosis than metastatic disease according to the published reports in the literature. Primary melanoma of the CNS may occur as intra-axial or extra-axial mass lesions or may be presented as meningeal spread. We describe the clinical features of 23-year-old male patient with solitary cerebral melanoma, including magnetic resonance imaging and histopathologic findings in light of literature. © 2013 Wolters Kluwer Health, Inc.
Squamous Cell Carcinoma Arising From Teratoma of the Ovary: Magnetic Resonance, Computed Tomography, and Pathological Findings
(I R O G Canada, inc, 2017) Celiker, F. Beyazal; Turan, A.; Beyazal, M.; Eroglu, H. Temel; Bulut, G.; Colcimen, N.; Polat, H. Beyazal
In the present case report, the authors investigated the clinicopathological characteristics of squamous cell carcinoma (SCC) arising from teratoma of the ovary and intended to report their clinical experience. Malignant transformation of ovarian teratoma is a quite rare condition with SCC observed to be the most common form of transformation. The present case was a 43-year-old female patient and her clinical presentation was abdominal pain, abdominal distension, and abdominal mass sensation. The patient underwent ultrasonography. After detection of a mass, magnetic resonance imaging (MRI) was performed. Surgery was performed on the patient and the pathological report revealed SCC arising from teratoma. The patient was evaluated retrospectively in terms of demographic characteristics, MRI, surgical findings, and prognosis.
Ultrasound-Guided Percutaneous Treatment of Abscess Foci in Different Localizations of the Body: Results of Three Year-Experience
(Yuzuncu Yil Universitesi Tip Fakultesi, 2015) Bulut, M.D.; Yavuz, A.; Bora, A.; Batur, A.; Beyazal, M.; Avcu, S.
In this study, we evaluated abscess foci which are found in different localizations of the body, diagnosed with US, CT and MRI and performed US-guided percutaneus drainage. We evaluated the effectiveness of treatment, etiologic factors, organs and localizations of abscess in the cases who underwent drainage. A total of 63 patients diagnosed with abscess in different tissues and organs, had US-guided percutaneous drainage performed (34 male, 29 female aged between 1-75 years), and 68 abscess foci were analysed. Abscess size varied between 2.5-21 cm and the mean diameter was detected as 8 cm. Diagnosis of abscess was made with US in 45 cases, CT in 23 cases and MRI in 6 cases. While 48 out of 68 abscess foci were simple, 20 were multilocular and contained septations. Air was observed in 19 of all abscess foci. Clinical findings of abscess completely resolved in 60 out of 63 patients who underwent abscess drainage (95.2%). In 3 abscess, the abscess cavity did not shrink as desired due to multiloculation, dense content, adhesions and fistulization. A drainage catheter had also been inserted, so a decision of surgical therapy was made. Secondary drainage was applied due to recurrence in 2 patients. Thirty two abscess foci (47%) developed postoperatively. Complications were not observed in any of the cases. The duration of catheter was calculated as 5-23 days (mean 10.5 days). US-guided percutaneous drainage should be the primarily preferred method in treatment of abscess and collections as it is easily applicable, does not require general anesthesia, is well tolerated, and has high success and low complication rates. © 2015, Yuzuncu Yil Universitesi Tip Fakultesi.

Us and Ct Findings of Hibernoma in an Unusual Location
(2013) Yavuz, A.; Bora, A.; Beyazal, M.; Göya, C.
Hibernomas are asymptomatic, slow-growing tumors occurring in the anatomical sites where of brown fatty tissue was found in fetal life such as inter-scapular region or thigh. Retroperitoneal localization is an unusual site for this tumor and only few cases have been published in the literature. These tumors are benign in nature without any recurrence after total excision or evidence of metastasis. The purpose of this presentation is to demonstrate the US and CT findings of retroperitoneal hibernoma with the review of the literature.
