Desmoid tumours are rare mesenchymal tumours, often locally invasive and characteristically associated with a high local recurrence rate after resection. A potential aetiological role for female hormones is indicated. Pregnancy-associated desmoid tumours are almost exclusively located in the abdominal wall. An essential issue is how to counsel women who have had a pregnancy-associated desmoid tumour and subsequently wish to bear a child. A considerably rare case of a patient with a resection of a giant pregnancy-associated, 33 cm in diameter, intra-abdominal desmoid tumour is presented. After a subsequent pregnancy, the patient delivered healthy twins 26 months later. Fifty-four months after treatment, there are no signs of recurrent or second desmoid tumour. Although rarely located in the abdomen, pregnancy-associated desmoid tumours should be included in the differential diagnosis of intra-abdominal tumours detected during or shortly after pregnancy. Based on this case and a few others reported in the literature, subsequent pregnancy does not necessarily seem to be a risk factor for recurrent or new disease.

The aim of this study is to investigate the possibility of predicting histological grade in patients with endometrial cancer on the basis of intravoxel incoherent motion (IVIM)-related histogram analysis parameters. This prospective study included 52 women with endometrial cancer (EC) who underwent MR imaging as initial staging in our hospital, allocated into low-grade (G1 and G2) and high-grade (G3) tumors according to the pathology reports. Regions of interest (ROIs) were drawn on the diffusion weighted images and apparent diffusion coefficient (ADC), true diffusivity (D), and perfusion fraction (f) using diffusion models were computed. Mean, median, skewness, kurtosis, and interquartile range (IQR) were calculated from the whole-tumor histogram. The IQR of the diffusion coefficient (D) was significantly lower in the low-grade tumors from that of the high-grade group with an adjusted p-value of less than 5% (0.048). The ROC curve analysis results of the statistically significant IQR of the D yielded an accuracy, sensitivity, and specificity of 74.5%, 70.1%, and 76.5% respectively, for discriminating low from high-grade tumors, with an optimal cutoff of 0.206 (×10⁻³ mm²/s) and an AUC of 75.4% (95% CI: 62.1 to 88.8). The IVIM modeling coupled with histogram analysis techniques is promising for preoperative differentiation between low- and high-grade EC tumors.

The peculiar anatomy of pancreatic ducts in pancreas divisum (PD) may interfere with the development of acute chronic pancreatitis. In the presented case, PD influenced the evolution of lesions after pancreatic trauma. A 38 years old patient refferred to our hospital with recurrent episodes of mild pancreatitis during the last two years. The first episode occurred four months after blunt abdominal trauma. Endoscopic Retrograde Cholangiopancreatography, Magnetic Resonance Imaging of upper abdomen and Magnetic Resonance Cholangiopancreatography disclosed pancreas divisum, changes consistent with chronic pancreatitis in the dorsal pancreatic duct, atrophy in the body and tail of the pancreas and a pseudocyst in the pancreatic head, that was drained endoscopically. Pancreas Divisum may interfere with the evolution of posttraumatic changes in the pancreas after blunt abdominal trauma.
