    Giant dedifferentiated retroperitoneal liposarcoma: CT and MRI findings
    (Elsevier BV, 2004) Unal B.; Bilgili Y.K.; Batislam E.; Erdogan S.
    We present computed tomography, magnetic resonance imaging and pathologic findings of a 52-year-old female with a giant dedifferentiated retroperitoneal liposarcoma in which well differentiated lipoma-like and dedifferentiated components are found together. Dedifferentiated components of the mass showed various degrees of enhancement and revealed no suppression with fat saturation techniques. The diagnosis of dedifferentiated liposarcoma should be kept in mind when a mass is found with retroperitoneal localization, intense of contrast enhancement, calcifications, invasion of adjacent tissues, necrosis and haemorrhage, and the absence of fat suppression. © 2004 Elsevier Ireland Ltd.

    Medial orbital wall protrusion: Computed tomography findings
    (Elsevier BV, 2004) Kendi T.K.; Rodrigez C.; Kemal G.; Bilgili Y.K.; Huvaj S.
    We report a case with a defect in the medial orbital wall, causing a protrusion of orbital contents into the ethmoidal cells. Both the coronal and axial computed tomography of the paranasal sinuses demonstrated the protrusion and focal wall defect properly. © 2004 Elsevier Ireland Ltd. All rights reserved.

    Retrobulbar hemodynamics during healthy and preeclamptic pregnancy
    (2012) Onaran Z.; Bilgili Y.K.; Yilmazbaş P.
    Objective: We aimed to evaluate retrobulbar hemodynamics during healthy and preeclamptic pregnancy. Methods: We studied retrobulbar hemodynamics in 21 healthy pregnant, 20 preeclamptic and 21 non-pregnant fertile women. The peak systolic velocity, end-diastolic velocity and resistivity index (RI) of the ophthalmic artery (OA), central retinal artery (CRA) and posterior ciliary artery (PCA) were measured by color Doppler imaging. Results: The systolic and diastolic blood pressures of the preeclamptic women (155±8.5 and 105±7.5 mmHg, respectively) were significantly higher than those of healthy pregnant women (110±5.5 and 70±7.5 mmHg, respectively, p=0.008). The RI values of OA, CRA and PCA in healthy pregnant women were significantly lower than those of the non-pregnant women. The RI of the CRA and PCA in preeclamptic women were significantly higher than those of healthy pregnant women. Although there was no statistical significant difference, the RI of the OA was lower in preeclamptic women than healthy pregnant women. Conclusion: Resistance of all retrobulbar arteries decreased during healthy pregnancy. On the other hand, increased resistance was detected in PCA and CRA, besides the nonsignificant decrease in OA during preeclamptic pregnancy. Different auto regulator control mechanisms in response to hypertension seem to be responsible for the different conducts of different sized arteries of orbita during preeclamptic pregnancy. ©Copyright 2012 by Gazi University Medical Faculty.
