Published: February 2018

Amyloidosis is a rare disease defined by accumulation of extracellular amyloid systemically or within a specific organ. Localized amyloidosis of the genitourinary system is extremely rare, with the predominate location being the bladder. The imaging findings are often nonspecific and mimic urothelial carcinoma. We present a 49-year-old woman with a chief complaint of flank pain. A filling defect was discovered on radiological imaging. The defect was subsequently biopsied and proven to be a primary amyloidosis of the renal pelvis. We then review the radiological findings of amyloidosis of the genitourinary system.

Primary amyloidosis (AL type) is a systemic disease that can lead to structural and functional damage to organs and tissues such as the kidney, heart and liver with non-specific symptoms. Most of the affected patients develop thyroid infiltration and thus diffuse enlargement of the thyroid gland, while cases leading to hypothyroidism are exceedingly rare. Some researchers have analyzed thyroid function in newly diagnosed patients with AL amyloidosis, and found that the incidence of overt hypothyroidism is only 7%.

Introduction And Objectives: Cardiac amyloidosis (CA) is a prevalent yet underdiagnosed heart condition characterized by the abnormal accumulation of amyloid fibres, frequently resulting in heart failure (HF), particularly in older people. Despite advancements in non-invasive diagnostic techniques and treatments, the epidemiology of CA patients remains inadequately understood. This nationwide retrospective observational study sought to comprehensively investigate CA patients' characteristics, mortality, and readmission patterns.

POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal Protein, Skin changes) is a syndrome that involves a monoclonal B-cell proliferation, most often plasmacytic, and a variable number of manifestations listed or not in the acronym. These manifestations include sclerotic bone lesions, plasmacytic Castleman disease, papillary edema, peripheral edema, ascites, thrombocytosis and/or polycythemia, venous and/or arterial thrombosis, and renal, pulmonary, and cardiac impairments . Diagnosis is often delayed due to the rarity of this entity and its clinical polymorphism, which can mimic other neurological disorders.

Importance: Early detection of brain amyloidosis (Aβ+) is pivotal for diagnosing Alzheimer's disease (AD) and optimizing patient management, especially in light of emerging treatments. While plasma biomarkers are promising, their combined diagnostic value through specific ratios remains underexplored.

Objective: To evaluate the diagnostic accuracy of plasma pTau isoform (pTau181 and pTau217) to Aβ42 ratios in detecting Aβ+ status.
