    Purpose: We aimed to investigate whether there are any differences in apparent diffusion coefficient (ADC) values obtained from colorectal liver metastases (CRLM) according to Kirsten rat sarcoma (KRAS) gene mutation status.

    Papillary Lesions of the Breast: Addition of DWI and TIRM Sequences to Routine Breast MRI Could Help in Differentiation Benign from Malignant

    Aim: We aimed to investigate the magnetic resonance imaging (MRI) features of benign, atypical, or malignant papillary breast lesions and to assess the additional value of diffusion-weighted imaging (DWI) and turbo inversion recovery magnitude (TIRM) sequences to routine breast MRI. Background: Differentiation between benign and malignant papillary breast lesions is essential for patient management. However, morphologic features and enhancement patterns of malignant papillary lesions may overlap with those of benign papilloma. Methods: Seventy-two papillary breast lesions (50 benign, 22 atypical or malignant) were included in the current study, retrospectively. We divided the patients into two groups: benign papillary breast lesions and atypical or malignant papillary breast lesions. Morphologic, dynamic, turbo inversion recovery magnitude (TIRM) values and diffusion features of the papillary lesions were compared between two groups. Results: Benign papillary lesions were smaller in size (p=0.006 and p=0.005, for radiologists 1 and 2 respectively), closer to the areola (p=0.045 and 0.049 for radiologist 1 and 2 respectively), and had higher ADC values (p=0.001 for two radiologists) than the atypical or malignant group. ROC curves showed diagnostic accuracy for ADC (AUC=0.770 and 0.762, p & lt; 0.0001 for two radiologists), and showed a cut-off value of <= 957 x 10-6 mm(2/s) (radiologist 1) and <= 910 x 10-6 mm(2/s) (radiologist 2). Conclusion: MRI is a useful method for differentiation between benign and malignant papillary breast lesions. Centrally located, lesser in size, and higher ADC values should be considered benign, whereas peripherally located, larger in size, and lower ADC values should be considered malignant.

    MR Enterography Features of Jejunal Lipoma Causing Intussusception: A Unique Case Report
    (2020-05-13T04:00:00Z) KILINÇ, YAĞMUR BAŞAK; SARI, LÜTFULLAH; KARABULUT, ÜMMÜHAN EBRU; AYKAN, MAHMUT ESAT; TOPRAK, HÜSEYİN; KILINÇ, YAĞMUR BAŞAK; SARI, LÜTFULLAH; KARABULUT, ÜMMÜHAN EBRU; AYKAN, MAHMUT ESAT; TOPRAK, HÜSEYİN
    Intussusception usually occurs in children due to benign causes, whereas in adults, it is mostly caused by malign causes in the colon. On the other hand, the causes of small bowel intussusceptions in adulthood are usually benign, such as polyps, lipomas, adenomas, and Meckel-s diverticulum. Intestinal lipomas are an uncommon entity among benign tumors. Here, we present MR enterography features of jejunojejunal intussusception caused by an intramural lipoma.

    BACKGROUND: Groove pancreatitis (GP) is a rare form of chronic pancreatitis that is less common and is now gaining awareness with multimodal imaging modalities. Our aim is to analyze the mid-long term outcomes of patients diagnosed with GP with different treatment approaches.

    Uncommon Testicular Germ Cell Tumor Thrombus in Azygos Vein Detected by FDG PET/CT
    (2021-07-01T00:00:00Z) PEKER, ABDUSSELİM ADİL; TOPRAK, HÜSEYİN; YASİN, Ayşe İrem; AYDIN, MEHMET; PEKER, ABDUSSELİM ADİL; TOPRAK, HÜSEYİN; YASİN, AYŞE İREM; AYDIN, MEHMET
    A 40-year old man admitted to the nuclear medicine department to undergo PET/CT for restaging of known testicular germ cell tumor. The patient had a history of orchiectomy for left testis and left nephrectomy with retroperitoneal lymph node dissection. Histopathology revealed testicular germ cell tumor. During the follow-up period, there is a rapidly expanding mass in posterior mediastinum. PET reveals increased FDG activity in the azygos vein. Contrast-enhanced CT of the thorax showed distended azygos vein with heterogeneously enhancing thrombus and peripheral fat stranding. Findings are consistent with azygos vein tumor thrombosis related to testicular germ cell tumor.
