Objective: The aim of this study was to assess the diffusion-weighted whole-body-MRI (WBMRI) in the initial staging of breast cancer at high risk of metastases in comparison with positron emission tomography (PET)-CT.
Methods: Forty-five women were prospectively enrolled. The inclusion criteria were female gender, age >18, invasive breast cancer, an initial PET-CT, and a performance status of 0-2.
Objective: To assess tumor response with diffusion-weighted MRI (DW-MRI) after a short preoperative radiotherapy in early-stage breast cancer (BCa).
Materials And Methods: This was a prospective, single-center pilot study. 3T-MRI were performed before and after radiotherapy.
To compare region of interest (ROI)-apparent diffusion coefficient (ADC) on diffusion-weighted imaging (DWI) measurements and Ki-67 proliferation index before and after neoadjuvant chemotherapy (NACT) for breast cancer. 55 women were enrolled in this prospective single-center study, with a final population of 47 women (49 cases of invasive breast cancer). ROI-ADC measurements were obtained on MRI before and after NACT and were compared to histological findings, including the Ki-67 index in the whole study population and in subgroups of "pathologic complete response" (pCR) and non-pCR.
View Article and Find Full Text PDFOvarian Sertoli-Leydig cell tumors (SLCTs) are extremely rare ovarian sex-cord stromal tumors. Alpha-fetoprotein (AFP) production by SLCTs is a rare event generally linked to the presence of hepatocytes or intestinal mucinous epithelium as heterologous elements. We report here a case of a 15-year-old female complaining about abdominal pain, constipation, and spaniomenorrhea with high level of serum AFP leading to a clinical suspicion of malignant germ cell tumor.

However wound problems occurred frequently and was documented in 5 of the 14 patients: 2 patients with a mastitis needing antibiotics, 2 patients developed a fistula with exudate needing antibiotics and local disinfection and 1 patient developed a fistula needing surgical reintervention. Other acute and late iatrogenic events were rather limited.

Methods: Between January 2016 and December 2019, 55 women were enrolled in this prospective single-center study. MRI was performed at three time points for each patient: before treatment (MRI 1: DW and DCE MRI), after one cycle of NAC (MRI 2: noncontrast DW MRI), and after completion of NAC before surgery (MRI 3: DW and DCE MRI).
Background: The ovarian-adnexal reporting and data system-magnetic resonance imaging (O-RADS-MRI) score decreases the incidence of indeterminate adnexal masses from 18% to 31% with ultrasound till 10.8% to 12.5% with MRI.

Their management essentially relies on imagery. We report the case of an 18 weeks-pregnant women presenting bilateral teratomas visualized by RMI.

Methods: Between January 2004 and December 2007, 337 cases from BI-RADS3 lesions underwent FNAC. Three to six needle passes were made on each patient.
To analyse the correlation between axillary ultrasonography (US), cell block (CBs) preparation, and histological diagnosis of lymph nodes from patients with primary breast cancer with the intention to assess the accuracy of cell block (CB) technique in preoperative staging. We tested a series of 26 patients who underwent axillary cell blocks from ultrasound guided fine-needle aspiration with histologic follow-up (axillary lymph nodes dissection). The specificity of axillary cell block was 100% vs.

Materials And Methods: Institutional review board approval for this study was obtained, and each patient gave written informed consent.
Aims: To determine the impact of preoperative use of breast magnetic resonance imaging (MRI) in therapeutic surgical approach in women with breast cancer.
Materials And Methods: Preoperative contrast-enhanced MRI of the breast was performed in 105 patients with suspected breast carcinomas. MRI findings were correlated with mammography (MMG) and ultrasonography (US).
Objective: The purpose of our study was to assess the usefulness of manganese dipyridoxyl diphosphate (Mn-DPDP)-enhanced T1-weighted MR cholangiography for evaluating patients with biliary-enteric anastomoses.
Conclusion: Mn-DPDP-enhanced T1-weighted MR cholangiography may provide useful functional information and may aid in the assessment of the patency of biliary-enteric anastomoses.
We report unusual findings in two patients with Langerhans' cell histiocytosis (LCH), namely a cervical mass lesion with extensive destruction of the posterior elements of a cervical vertebra and gastrointestinal lesions as part of multisystem involvement. The aim of our report is threefold. Firstly, LCH can be responsible for osteolysis of the vertebral posterior arches, with or without involvement of the vertebral body, and should be included in the differential diagnoses of cervical mass lesions.
View Article and Find Full Text PDFTwo cases of calcific tendinitis of gluteus maximus muscle are presented. The CT findings, including amorphous calcification without soft tissue mass and possible cortical erosion at the femoral enthesis of the gluteus maximus muscle, are highly suggestive of calcific tendinitis at this unusual but classical location. Ossifying entheses with well-defined cortical defect are frequent at the femoral insertion of the gluteus maximus muscle in asymptomatic subjects and must be differentiated from a real cortical erosion sometimes associated with these calcific tendinitis.
