2024年7月12日 · Calcium pyrophosphate dihydrate deposition (CPPD) disease, also known as pyrophosphate arthropathy or pseudogout, is defined by the co-occurrence of arthritis with evidence of calcium pyrophosphate dihydrate deposition within the articular cartilage.

CT-scan detected calcium deposit in 7 cases. MRI showed lesions going from the increased signal of the disk, to calcified or not-cystic lesion of the facet joints, an intramedullary mass mimicking a schwannoma. Histological examination established the diagnosis of CPPD in 21 patients in all studies.

2025年1月8日 · The radiological manifestations of calcium pyrophosphate deposition (CPPD) revolve around two main axes: the asymptomatic form and CPPD disease. The latter is a consequence of an immune response to calcium phosphate crystals.

2020年2月10日 · Final pathology report showed fragments of cartilage with calcium pyrophosphate crystal deposition supporting a diagnosis of acute CPP crystal arthritis of the lumbar spine (Figures 2 (a) – 2 (d) ).

2000年11月1日 · Calcium pyrophosphate dihydrate (CPPD) crystal is widespread in elderly persons and has various clinical presentation that can be confounding to clinicians. It is characterized by acute, subacute, or chronic joint inflammation and deposition of CPPD crystals in hyaline cartilage, fibrocartilage, and other soft tissue structures.

Results: Spinal CPPD was diagnosed in 37/152 (24.3%) CPPD patients. Patient with spinal involvement had more widespread peripheral CC. The cervical (n = 21) and lumbar (n = 19) segments were most involved. CT-scan was more sensitive than plain radiographs for detecting spinal calcifications.

2022年10月6日 · CT-scan detected calcium deposit in 7 cases. MRI showed lesions going from the increased signal of the disk, to calcified or not-cystic lesion of the facet joints, an intramedullary mass mimicking a schwannoma. Histological examination established the diagnosis of CPPD in 21 patients in all studies.

2024年6月1日 · Calcium pyrophosphate dihydrate crystal deposition disease (CPPD-CDD) refers to inflammatory arthropathy caused by CPPD depositing on articular cartilage, synovium, ligaments, tendons and other soft tissues (Rosenthal & Ryan, 2016).

2020年2月10日 · Inflammatory arthritis, such as pseudogout or otherwise referred to as calcium pyrophosphate (CPP) crystal arthritis or calcium pyrophosphate deposition (CPPD) disease, is characterized by the deposition of crystal formation and deposition in large joints. CPPD is known to affect the elderly populat …
