Results
From all 100 cases we have got 70 benign lesions:
- 53 casese of benign tumors and
- 17 cases of tumor-like lesions.
Malignant lesions were present in 30 cases:
- 26 of them were primary malignant tumors (Fig.2) and
- 4 cases were metastases (fig.4).
The overall imaging accuracy for benign tumors as well as malignant was 92%.
Nine cases (9%) were false positive:
- 4 benign tumors,
- one tumor-like lesion and
- 4 metastases.
False negative were two (2%) cases.
The correlation between imaging staging and histopathology was 63,6% for malignant tumors.
MRI had highest diagnostic accuracy (89%) compared to US and CT.
Ultrasonography had diagnostic accuracy of (78%) and at computed tomography diagnostic accuracy were (83%).
During our workDiagnostic imaging algorithm was created.
The idea was not to have over investigation of the suspected soft tissue lesion but in the same time not to miss malignant tumor.
For example when tumor is clearly lipoma on US and CT than we can suggesst to skip biopsy,
etc.
(Fig.1)
Histopathology after US-guided biopsy correlated in all surgical specimens.
