Results
The MR imaging features of our 40 clinical cases are listed in the Table(1),
10 cases were excluded due to presence of other bony lesions as enthesopathy,
spurs & tarsal tunnel syndrome,
also of the 20 control cases one case showed mild edema denoting mild form of plantar fascitis .
MR imaging criteria in 3 patients,
one patient aged 30 years,
the other two at age group (46-55) aging 47 & 50 years respectively,
these patients were having partial tear of the PS,
showed partial high T2-weighted signal intensity of the plantar fascia.
In the three patients,
abnormal thickening of the PA at the site of partial disruption was evident.
Tears involved the proximal PA was present in one case and no tear at the middle PA was observed.
The three cases showed edema in perifascial soft tissue with high signal intensity on T2-WI .
Fascial thickening & scar tissue was depicted with low signal intensity on T2-WI,
and STIR images.
MR imaging studies in the 27 patients with plantar fasciitis ,
10 patients at age group (25-35),
11 at age group (36-45) & 6 at age group (46-55) revealed the signal intensity changes of perifascial edema either superficial to (n = 11) or both superficial and deep to (n = 16) the PA .
In 13 patients,
the PA exhibited abnormal intrafascial high signal intensity on T2-weighted images,
STIR images,
or both.
The PA was abnormally thickened (5–7 mm) in 20 patients.
20 healthy non complaining control group were examined,
one person showed superfascial edema of the plantar fascia denoting mild fasciitis,
while the rest of the control group showed no abnormality.
Accordingly,
out of the 40 patients; 10 cases (25% ) were clinically complaining but radiologically free.
On the other hand,
one of the control non complaining group turned to have mild plantar fasciitis that accounts for 1/20 = 0.05%
