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.

BACKGROUND: Umbilical vein catheterization (UVC) is an early venous access route in newborns and is frequently used for delivering total parenteral nutrition (TPN) and medications. Vascular, hepatic parenchymal, and infectious complications of UVC can be seen rarely. OBJECTIVE: We present preterm neonates\" X-ray, US, and MRI findings with parenchymal TPN extravasation and portal vein thrombosis. Our case was the first case about MRI findings of TPNoma. CASE PRESENTATION: A 30 week female with a birth weight of 1340 g was born via Cesarean section. Due to the diagnosis of transient tachypnea of the newborn and prematurity, the infant was hospitalized in the neonatal intensive care unit. On the first day of hospitalization, UVC was inserted and TPN with 20% lipid content was started. After 10 days, UVC was removed and TPN treatment was continued with a piccline catheter. Abdominal US and portal venous Doppler examination was applied to the patient whose general condition deteriorated on the 12th day. US and Doppler revealed a lesion of 17x17x18mm in size with lobulated contour, hyperechoic heterogeneous internal structure, and no central or peripheral blood supply was observed in the left lobe of the liver. Moreover, a filling defect compatible with a thrombus was observed in the proximal part of the left portal vein. An abdominal MRI was performed to characterize this liver lesion. Axial T1 weighted and T2- weighted images showed a heterogeneous hyperintense lesion without contrast enhancement. Axial fat saturation T1-weighted and out of phase T1-weighted images showed a reduction in signal intensity. US and MRI examinations showed that the thrombosed umbilical vein ended superior to the lesion. In the differential diagnoses, fat-containing lesions such as lipoma-teratoma and fat-containing collection secondary to extravasation of TPN treatment via UVC were thought. CONCLUSION: In the differential diagnosis of liver localized lesions in newborns, UVC-related liver injury should be considered and the localization of the catheter tip should be checked. In case of the doubt based on US and X-ray findings, presence of fat on MRI could be diagnosed. Serious complications should be avoided with catheter revision or removal.

To evaluate breast MRI and DWI and demographic features of pleomorphic invasive lobular carcinoma (pILC) and classic invasive lobular carcinoma (cILC). Invasive lobular (ILC) is the second most common breast malignancy after invasive ductal carcinoma (IDC) and constitutes the 8-14% of all invasive breast cancers. ILC morphologically can be classified into the classic, alveolar, solid, tubulolobular, and pleomorphic subtypes according to WHO. This study was performed retrospectively. The MRI and demographic features of 18 patients with 23 pILC were compared with those 22 consecutive patients with 27 cILC. There was no significant difference in demographic features of patients, MR appearance, kinetics, and ADC values between two groups. pILC, an aggressive subtype of ILC, cannot be differentiated from cILC with breast MRI.

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.

© 2022 The Royal College of RadiologistsAIM: The purpose of this study was to evaluate meniscal and tibiofemoral cartilage injury in patients with trochlear dysplasia (TD) and investigate whether there were correlations between TD grade and meniscal and cartilage injury. In addition, the relationship between TD and mucoid degeneration of the anterior cruciate ligament (ACL-MD) was investigated. MATERİALS AND METHODS: Magnetic resonance imaging (MRI) examinations of 133 patients with TD were included in the study. TD was graded (types A, B, C, D). The tibial tuberosity (TT)–TG distance was also measured. The ACL was assessed for ACL-MD. Both menisci were evaluated for the degeneration and tears. Medial–lateral tibial plateau (MTP–LTP), medial–lateral femoral condyles (MFC–LFC), and trochlear cartilage were examined for focal cartilage defect (FCD). RESULTS: ACL-MD was present in 42 of the patients with TD (31.6%). There was a significant positive relationship between ACL-MD and TT–TG distance. Meniscal tear was detected in 40 (30.1%) of all patients. FCD were detected in the tibiofemoral compartments in 41 (30.8%) of 133 patients. There was a significant positive relationship between the presence of FCD in the LFC and the type of TD (p<0.01). FCD was present in the LFC of all cases in the type D. A significant positive relationship was found between the TT–TG distance and the presence of FCD, especially in the anterior part of LFC (p<0.01). There was a significant relationship between the lateral trochlear cartilage defect and the type of dysplasia (p=0.037). CONCLUSİON: TD is a significant risk factor for ACL-MD, meniscal, and tibiofemoral cartilage injury.
