Magnetic resonance imaging (MRI) is increasingly used in the diagnosis of multiple myeloma (MM). The new statement of the International Myeloma Working Group (IMWG) introduced the role of Whole-body Magnetic Resonance Imaging (WB-MRI) in the management of patients with this haematological disease. We report the case of a hospitalized patient in the haematology department, who was diagnosed with MM and investigated by WB-MRI in order to achieve a complete lesions' report, and staging of the disease. The presented case illustrates more lesions of the spine, long bones and the skull. Common MRI characteristics of MM lesions were defined as a nodular injuries, which were hypointense with T1-weighting, hyperintense with STIR and/or hyperintense with b-800 diffusion-weighting. WB-MRI examination was shown to be a sensitive imaging technique in evaluation of bone marrow and it was included in the DurieSalmon staging system PLUS.
Renal cell carcinoma (RCC) causes significant morbidity and mortality. Clear cell RCC (ccRCC) is the most common histologic subtype, with worse prognosis compared with other histologic subtypes. The indolent variant of ccRCC is the multilocular cystic RCC (McRCC). Imaging features reflect the various histological findings of each histologic subtypes. Recent advances in imaging technology permit early and more appropriate diagnosis of RCC and facilitate optimal management.
Prostate cancer (PC) is one of the most prevalent malignant tumour in men, especially in elderly patients. The aim of this paper is to present and illustrate the utility of multiparametric (MP) MRI in the diagnostic of PC. A 66 years old patient with clincal suspicion of PC was explored by MP MRI. The MR examination included T2-wi, dynamic contrast-enhanced (DCE) MRI and diffusion-weighted imaging (DWI) acquisitions. The final MR diagnosis was prostate tumor with the TNM-stage T4 N1 Mx. Radical prostatectomy revealed a Gleason score 7 (4+3) adenocarcinoma with extraprostatic extension. This case report shows the utility of MP MRI exam in characterizing and for the management of PC.
Pancreatic pseudocysts are often complications of acute pancreatitis and chronic pancreatitis, secondary to pancreatic trauma or pancreatic duct obstruction. Computer tomography (CT) is the standard investigation for the diagnosis of pancreatic pseudocysts, but Magnetic Resonance Imaging (MRI) is a better alternative for the detection and characterisation of this pathology. We present a case of a 43 year old male admitted with ascites who was investigated mainly by CT, both pre and post-operative, but also by MRI. The presented case illustrates an arterialized pancreatic pseudocyst, which is a rare complication associated with chronic pancreatitis. This case shows the importance of CT examination in pancreatic cystic lesions with vascular involvement. For unstable patients and modified cystic mass content, CT is the best imaging choice for evaluation and characterization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
