- PublicationOpen AccessCT and MRI Findings of Hepatic Involvement in Rendu-Osler-Weber Disease.(2012-01-01) Bilgin, MEHMET; Yildiz, S; Toprak, HÜSEYİN; AHMAD, ISSAM CHEIKH; KOCAKOÇ, ERCAN; BİLGİN, MEHMET; YILDIZ, ŞEYMA; TOPRAK, HÜSEYİNRendu-Osler-Weber disease is a rare autosomal dominant disorder. Hepatic involvement manifests itself as vascular, parenchymal, and biliary lesions with characteristic telangiectasias and vascular shunts. In a 37-year-old female patient, dynamic contrastenhanced upper abdominal CT and MRI were performed. CT and MRI revealed dilated celiac trunk and hepatic artery. On early arterial phase, dilated hepatic veins showed significant enhancement. On arterial and portal venous phases, liver showed significantly heterogeneous contrast enhancement and showed homogenous enhancement in the hepatic parenchymal phase. On the magnetic resonance cholangiopancreatography, irregular biliary ducts with strictures and dilatation were seen.

- PublicationOpen AccessRadiologic findings of idiopathic granulomatous mastitis(2015-03-01) Yildiz, Seyma; Aralasmak, AYŞE; Kadioglu, HÜSEYİN; Toprak, HÜSEYİN; YETİS, Huseyin; Gucin, ZÜHAL; KOCAKOC, Ercan; YILDIZ, ŞEYMA; ARALAŞMAK, AYŞE; KADIOĞLU, HÜSEYİN; TOPRAK, HÜSEYİN; GÜCİN, ZÜHALAim: To describe the radiological findings of idiopathic granulomatous mastitis (IGM). Material and methods: Radiologic findings of 30 women with histopathological diagnosis of IGM were retrospectively evaluated. All had breast feeding history. All the patients had ultrasonography (US), with 12 of them having additional Doppler US. Of 30 patients, 11 had mammography (MG) and 5 MRI. Results: US showed multiple irregular hypoechoic masses and collection areas with tubular connections in 25 of 30. The collection area with low-level internal echoes but without tubular connections, suggesting an abscess were seen in 2 of 30 (6.6%); a hypoechoic mass with an indistinct border in 2 of 30 (6.6%); multiple milimetric hypoechoic nodular masses in 1 of 30 (3.3%). On MG, normal findings were noted in 5 (45.4%); focal asymmetric density in 4 (36.4%), parenchymal distortion in 1 (9%) and diffuse asymmetric opacity with trabecular thickening in 1 (9%) of 30 patients. On MRI, segmental T2 hyperintensity with contrast-enhancement on T1 were seen in 4 of 5 (80%). An enhancing T2 hypointense mass with irregular margin was present in 1 of 5 (20%). Time-signal intensity curve of lesions showed slow enhancement in 1 and moderate in 4 of 5 patients. Conclusions: In IGM, MG findings were nonspecific. In US, multiple irregular hypoechoic masses and collections with tubular connections with fingerlike aspects, and fistulae formation to the skin in patients with breastfeeding history suggested IGM rather than carcinoma. Due to the limited number of patients, no conclusion was reached regarding MRI of IGM.
- PublicationMetadata onlyMRI and MRS findings in fucosidosis; a rare lysosomal storage disease(2016-04-01) EDIZ, Suna Sahin; Aralasmak, AYŞE; YILMAZ, TEMEL FATİH; Toprak, HÜSEYİN; Yesil, GÖZDE; Alkan, ALPAY; ARALAŞMAK, AYŞE; YILMAZ, TEMEL FATİH; TOPRAK, HÜSEYİN; YEŞİL, GÖZDE; ALKAN, ALPAYFucosidosis is a rare lysosomal storage disorder caused by deficient activity of the enzyme L-fucosidase in all tissues. We presented magnetic resonance imaging [MRI] and MR spectroscopy [MRS] findings of a 4-year-old boy with genetically proven fucosidosis. He had a history and clinical findings of recurrent sinopulmonary infections, hypertonicity on lower extremities, gingival hypertrophy, bilateral ptosis, angiokeratoma corporis diffusum, and dysostosis multiplex. He had no organomegaly and urine glycosaminoglycan analysis were normal. MRI revealed abnormalities within the globus pallidus and periventricular and subcortical white matter. MRS showed a peak at the 3.8-3.9 ppm as a result of accumulating carbohydrate containing macromolecules and another peak at 1.2 which was doublet and inverted on TE 135, suggesting fructose peak. A final diagnosis of fucosidosis was proved by mutational analysis of FUCA1 gene which is responsible for the Fucosidosis phenotype. Two recent reports of MRS of two patients demonstrated that MRS is specific for fucosidosis. In this case, we aim to discuss fucosidosis with MRI and MRS findings accompanied by the literature.
