Findings and procedure details
Our young patient was underwent to a dynamic ultrasonographic study,
performing an axial and longitudinal scan of the mass with a 18 MHz linear transducer (MyLab TWICE,
Esaote Biomedica,
Genoa,
Italy) ,
with the patient in upright position and tibialis anterior muscle tension,
that showed small hypoechoic formations through fascia cruris defect crossed by perforating vessels (fig.
1-3) ,
to report to small hernias intermuscular adipose tissue,
condition that occurred when some position of the leg increase the pressure inside.
Subsequently,
she performed a MRI exam (Siemens Aera 1.5 T,
Monaco,
Germany) of both legs,
by T1 weighted,
T2 weighted and T2 fat suppression sequences,
which evidenced hyperintense masses in T1 and T2 weighted sequences (fig.
4a,
4d),
hypointense in T2 fat suppression sequence (fig.
4b),
most between tibialis anterior and extensor muscles.
Such signal features,
along with site and morphology of the masses,
confirmed the ultrasound diagnostic hypothesis and finally excluded other conditions such as muscle herniation,
lipomas,
angiolipomas,
fibromas .
