Possible conjectures for the aggravation of clinical symptoms in the pericollapse stage include deteriorative structural instability of the femoral head, enhanced secretion of inflammatory mediators, elevated intramedullary pressure, and increase in hyperstatic pressure caused by
joint effusion, etc.[18],[19],[20],[22],[33],[35] There are, of course, exceptions.
Mild villous frond-like fatty subsynovial hyperplasia is present in the suprapatellar bursa associated with synovial proliferation, which is enhanced after iv administration of gadolinium, and
joint effusion (arrows).
Joint effusion and synovial thickening was observed in two cases (67%).
MR imaging obtained four months postdiagnosis demonstrated complete resolution of the findings of bone marrow edema and
joint effusion. There was no evidence of contralateral hip involvement or complications such as fracture (Figure 2B).
However, most symptomatic patients evaluated showed neither bone alterations nor signal intensity consistent with
joint effusion.
The diagnosis of disseminated gonococcal infection is usually made by clinical examination and culture of specimens from the genital tract, blood, or

Specifically, they could not make clear-cut distinctions between signals of slow motion sodium ions in the cartilage from those of free sodium ions in synovial fluid and

On exam, she has no evidence of
joint effusion but has tenderness along the patellar facets, a positive patellar apprehension test, and pain on squatting.
The presence of a knee
joint effusion probably relates to stress or injury.
The presence of other findings on ultrasound were recorded in the symptomatic and asymptomatic shoulders, the appearance of the biceps tendon, SASD bursa, the presence of a glenohumeral
joint effusion, signs of impingement according to Neer's classification and size of the tears.
An earlier MRI study revealed changes in the joint cartilage and signs of
joint effusion - fluid in the joint after only 30 minutes of jogging by recreational runners, according to Shellock.
X-ray of the left knee showed a
joint effusion. MRI of his left knee also demonstrated a
joint effusion with a popliteal cyst and synovial thickening (Figure 1).
