Objectives: High resolution ultrasound (HRUS) is increasingly popular
in the assessment of soft tissue tumours. This retrospective study evaluates
the reliability of HRUS in diagnosing soft tissue tumours of the hand and
wrist, compared to clinical evaluation, intraoperative findings and
histological examination.
Methods: Sixty-three patients with soft tissue tumours of the hand
and wrist were first evaluated clinically investigated. HRUS was then
performed using a 5-17 MHz broadband linear probe, with the radiologist
blinded to the clinical interpretation. The patient was scheduled for
operation depending upon suspected pathology. Histological examination was
routinely obtained during surgery.
Results: Thirty-one patients underwent surgery. Of the 16 solid
lesions HRUS was right in 15 cases (94%). Only nine of these 16 lesions
(56%) were correctly diagnosed on clinical examination (p= 0.041). All 15
cysts were correctly diagnosed by HRUS, whereas clinical examination alone
correctly diagnosed a cyst in 14 patients (not significant).
Conclusion: No significant difference was found in the
differentiation of cystic and solid lesions comparing HRUS and clinical
examination. HRUS is significantly better than clinical diagnosis alone in
distinguishing the type of solid lesions. Further benefits of HRUS include
the identification of atypically localised cysts and improved preoperative
planning.
