18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) and diffusion weighted magnetic resonance imaging with background signal suppression (DWIBS) are two powerful functional imaging modalities in the evaluation of the malignant plasma cell (PC) disease multiple myeloma (MM). Preliminary observations have suggested that MM patients with extensive disease according to DWIBS may be reported as being disease-free on FDG-PET ("PET-false-negative"). The aim of this study was to describe the proportion of PET-false-negativity in a representative set of 227 newly diagnosed MM patients with simultaneous assessment of FDG-PET and DWIBS, and to identify tumor-intrinsic features associated with this pattern...

Radiology provides a crucial clinical adjunct in patients with plasma cell disorders, in particular multiple myeloma, and its uses are evolving and expanding. This pictorial review illustrates the role of imaging throughout the patient's clinical course, with specific reference to recently updated international diagnostic criteria. At presentation, imaging optimises characterisation and staging of the plasma-cell disorder, while later in the course of the disease, its roles include the monitoring of disease progression, assessment of post-treatment response and the investigation of clinical deterioration...

PET-magnetic resonance (MR) is a hybrid imaging modality that combines PET and MR. Evidence for this new modality is in the process of being developed, but both component modalities are well tested in the diagnosis and management of multiple myeloma. It allows advanced bimodality imaging of the whole body with an adaptable field of view and it can be used for monitoring plasma cell dyscrasias for progression to multiple myeloma, for assessing disease burden in patients with known multiple myeloma, for assessing response to therapy and relapse after remission, and for radiation therapy treatment planning...

Hematologic malignancies comprise a set of prevalent yet clinically diverse diseases that can affect every organ system. Because blood components originate in bone marrow, it is no surprise that bone marrow is a common location for both primary and metastatic hematologic neoplasms. Findings of hematologic malignancy can be seen with most imaging modalities including radiography, computed tomography (CT), technetium 99m ((99m)Tc) methylene diphosphonate (MDP) bone scanning, fluorine 18 ((18)F) fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT, and magnetic resonance (MR) imaging...

BACKGROUND: Although the diagnosis of subdural hematoma is usually straightforward, occasionally it may be erroneous, leading to mistakes in the treatment. For example, leptomeningeal malignancies, even in the absence of bleeding, may clinically and radiologically mimic subdural hemorrhage. OBJECTIVE: To stress the importance of not only intuitive thinking but also in analytic thinking in appropriate and accurate treatment strategies. METHODS AND ILLUSTRATIVE CASE: In this report, the clinical and radiological pitfalls in differentiating malignant leptomeningeal infiltration and subdural hematomas are discussed...

A 47-year-old man presented with abdominal pain, vomiting, and bone pain. Laboratory findings revealed severe hypercalcemia, anemia, and renal insufficiency with decreased serum parathyroid hormone. FDG PET/CT was performed for characteristics suggestive of multiple myeloma and other occult malignancy. The images revealed widespread osteolytic lesions with only 1 focus of definite abnormal FDG uptake. B-cell acute lymphoblastic leukemia was confirmed by pathological examination following bone marrow biopsy.

Ga prostate-specific membrane antigen (PSMA) HBED-CC PET/CT in a 65-year-old man with first diagnosis of prostate cancer (PC) and a history of multiple myeloma showing multifocal PSMA ligand uptake in the skeleton with corresponding osteolytic lesions in CT. Although osteolytic bone metastases are very rare in PC, PSMA expression in PET raised the suspicion of PC bone metastases. Bone marrow biopsy excluded PC metastases with immunohistochemistry showing endothelial expression of PSMA in small vessels within the myeloma...

The International Myeloma Working Group consensus aimed to provide recommendations for the optimal use of (18)fluorodeoxyglucose ((18)F-FDG) PET/CT in patients with multiple myeloma and other plasma cell disorders, including smouldering multiple myeloma and solitary plasmacytoma. (18)F-FDG PET/CT can be considered a valuable tool for the work-up of patients with both newly diagnosed and relapsed or refractory multiple myeloma because it assesses bone damage with relatively high sensitivity and specificity, and detects extramedullary sites of proliferating clonal plasma cells while providing important prognostic information...

Posterior reversible encephalopathy syndrome (PRES) is a neurological condition characterized by headaches, visual disturbances, and seizures. A magnetic resonance imaging (MRI) scan of an affected brain typically shows symmetrical white matter edema in the posterior cerebral hemispheres. The onset of PRES can constitute a medical emergency, especially when accompanied by status epilepticus. If promptly recognized and treated, the clinical syndrome and associated radiological findings are usually resolved in a matter of weeks or months...

Multiple myeloma is a lymphoproliferative disease that may involve the bone marrow as well as extramedullary soft tissues. However, laryngeal localization of multiple myeloma is extremely rare. We herein present the case of a 68-year-old male patient with a history of dyspnea, dysphonia and dysphagia. Laryngoscopic examination revealed a lesion involving the right glottis and right vestibular (false) vocal fold, with absence of ipsilateral laryngeal motility and constriction of the airway. Computed tomography and magnetic resonance imaging revealed a gross swelling infiltrating the right glottis and right false vocal fold, sized 33×19×33 mm, with sub-centimeter laterocervical lymph nodes bilaterally...

PURPOSE: Dickkopf 1 (DKK1) has been extensively investigated in mouse models of multiple myeloma, which results in osteolytic bone lesions. Elevated DKK1 levels in bone marrow plasma and serum inhibit the differentiation of osteoblast precursors. Present pharmaceutical approaches to target bone lesions are limited to antiresorptive agents. In this study, we developed a cyclized oligopeptide against DKK1-low density lipoprotein receptor-related protein (LRP) 5/6 interaction and tested the effects of the oligopeptide on tumor burden...

Conjunctival amyloidosis is a very rare disease, and its presence may be a sign of systemic amyloidosis. We present our ocular and systemic findings in a patient with conjunctival amyloidosis. A 43-year-old man had repeated subconjunctival hemorrhages (SCHs) for two years and was referred to the Chiba University Hospital. He had comprehensive ophthalmological and systemic examinations to determine the cause of the SCHs. His visual acuities were 1.2 OU, and the intraocular pressures were 13-14 mmHg OU. Magnetic resonance imaging was normal...

Plasmablastic lymphoma, a rare highly aggressive non-Hodgkin's lymphoma subtype, often associated with HIV infection, is a close differential diagnosis of plasmablastic myeloma. The 2 conditions may be morphologically and immunophenotypically identical. However, differentiating between the 2 conditions is critical for adequate patient management. Herein, we describe an unusual case of plasmablastic myeloma with biclonal gammopathy which was initially diagnosed as plasmablastic lymphoma based on lymph node biopsy and immunohistochemistry (IHC) results...

Multiple myeloma (MM) is characterized by abnormal proliferation of plasma cells in the bone marrow leading to symptoms of anemia, renal failure, hypercalcemia, and bone lesions. Bone imaging is critical for the diagnosis, staging, assessment for the presence and extent of bone lesions, and initial treatment of MM. Skeletal survey is the preferred initial imaging modality due to its availability and low cost. However, it has poor sensitivity and patients with occult myeloma may escape detection, delaying their diagnosis and treatment...

Magnetic resonance imaging (MRI) is the most sensitive imaging technique for the detection of bone marrow infiltration, and has therefore recently been included in the new diagnostic myeloma criteria, as proposed by the International Myeloma Working Group. Nevertheless, conventional MRI only provides anatomical information and is therefore only of limited use in the response assessment of patients with multiple myeloma. The additional information from functional MRI techniques, such as diffusion-weighted imaging and dynamic contrast-enhanced MRI, can improve the detection rate of bone marrow infiltration and the assessment of response...
