MR imaging findings in transient osteoporosis of the hip

Degenerative endplate changes of the lumbosacral spine: Dynamic contrast‐enhanced MRI profiles related to age, sex, and spinal level

“…The similarity of MR appearance of degenerative endplate changes to that of ischemic necrosis of the hip has indicated possible links to vascular impairment, focal inflammation, and edema or ischemia (1,38). DCE MRI studies have shown delayed peak enhancement in transient osteoporosis of the hip and increased enhancement rate in rheumatoid arthritis and may support the observation of delayed and increased maximum enhancement in degenerative changes in the presence of local edema or inflammation (25,26). Other studies have shown decreasing enhancement slope with increasing fatty marrow percentage and may explain decreased WIN in degenerative changes in presence of fatty marrow (27).…”

Migratory transient osteoporosis: atypical migration to the bilateral knee after childbirth

“…[15] It has also been reported that TO was improved by the termination of pregnancy in severe cases that do not respond to the other treatment. [16] Interestingly in our case, a remission was not seen during the postpartum period and migration occurred other joints.…”

“…When we analyzed the published medical literature, we determined that 5-42% of cases diagnosed with TO had migratory characteristics such as in our case. [3,16,18] Treatment of TO is conservative. The restriction of weight bearing on the involved joint can help prevent formation of microfractures on the joint surface which may progress to collapse.…”

Gebelik ile ilişkili Osteoporoz

“…Manyetik rezonans görüntüleme (MRG) T1 ağırlıklı kesitlerde düşük sinyal yoğunluğu, T2 ağırlıklı kesitlerde ise yüksek sinyal yoğunluğu kemik iliği ödemini göstermektedir (33). MRG bu olguların avasküler nekrozdan ayırımının yapılmasında önemlidir (34). Olguların çok küçük bir kısmında femoral kırık gelişse de hemen hemen hepsinde kırıksız spontan iyileşme gözlenir (30).…”
