Article Synopsis
- - The study investigates the reliability of Diffusion Kurtosis Imaging (DKI) parameters by comparing them with perfusion metrics from Dynamic Contrast Enhanced (DCE) and Dynamic Susceptibility Contrast (DSC) MRI techniques in primary central nervous system lymphoma (PCNSL) patients.
- - Analysis of 15 lesions from patients with Epstein-Barr Virus negative PCNSL showed significant correlations, notably between DKI parameters and both DCE/DSC metrics, suggesting that DKI adds valuable insights beyond traditional diffusion models.
- - The findings indicate a strong inverse correlation between several DKI parameters and perfusion metrics, pointing to DKI's potential to enhance understanding of tumor characteristics and inform clinical practices.
Background: Intraductal papillary neoplasms of the bile duct (IPNB) are rare precancerous lesions with implications for the development of cholangiocarcinoma (CCA). Recognizing IPNB and managing its recurrence pose challenges in clinical practice. We present two cases.

- The study evaluated the effectiveness of MRI sequences (T1-TSE, T2-TSE, and 3D FLAIR) with and without the Compressed-SENSE technique by measuring contrast, contrast-to-noise ratio (CNR), and signal-to-noise ratio (SNR).
- A total of 142 MRI images were analyzed, with regions of interest marked by radiologists to assess differences in CNS structures (white matter, grey matter, cerebrospinal fluid).
- Results showed that while Compressed-SENSE improved image quality in specific T1-TSE sequences, it had mixed effects on contrast values in other sequences, ultimately demonstrating its potential for faster MRI scans without compromising essential diagnostic information.
Peliosis hepatis (PH) is a rare benign pathological entity characterised by dilatation of the hepatic sinusoids. It has been reported to be associated with infection or malignancy, but the aetiology of PH remains unknown. Distinguishing PH from other malignancies can be difficult on imaging studies.

We report a case of a 35-year-old female who received an allogenic hematopoietic stem cell transplantation for acute myeloid leukemia, suffering from maxillo-spheno-ethmoidal rhinosinusitis which was complicated by cavernous sinus thrombosis, orbital cellulitis, optic ischemia and cerebritis.
