2. PURPOSE
Gossypiboma or textiloma may be
disclosed incidentally by ultrasound in
routine check-up.
The aim of the present study was to
evaluate the findings of conventional
ultrasound in the detection of
gossypiboma.

3. METHODS and MATERIALS
 All patients received conventional
ultrasound, and then MDCT to confirm the
ultrasound findings and rule out a
malignant mass.

4. RESULTS
 From 1995 to 2011, there are 12 cases
which were detected by ultrasound and
later confirmed by MDCT and surgery.
 The time point to detect gossypiboma are
in range from one 1 month to 23 years
post-op.
 Most of cases are in fibrinous stage and 3
cases in early stage.

5. RESULTS (cont.)
 Ultrasound findings of gossypiboma are
cystic formation masses with echogenic
structure, hypoechogenic contour and
strong posterior shadowing.
 3 types: (1) echogenic mass with
"umbrella sign" (Dr Hai Thanh Phan,
1988) ; (2) cystic mass encapsulates
striped structure inside; (3) non specified
hypoechoic or mixed mass.

6. Gossypiboma post cesarian for 5 months

7. Gossypiboma post removed left kidney for 7 years

8. Gossypiboma post removing R.kidney stone for 13 years

9. Gossypiboma post op for 23 years

10. Gossypiboma post appendicectomy for 14 months

11. Gossypiboma post cesarian for 1 month

12. Gossipiboma post removing R. thyroid nodule for 8 months

13. DISCUSSIONS
 With one’s own skills and experiences,
ultrasound is sensitive to detect gossypiboma
and can differentiate from a malignant mass.
 Umbrella sign may help although that is not a
specific finding in differentiating gossypiboma to
fecalith, abscess and real tumor.
 But MDCT (and MRI) play a valuable role in
identification the textile structure of retained
gauze in the abdomen.

14. CONCLUSIONS
 Ultrasound can be performed in the
detection of gossypiboma with reliable
results, in regarding of the scar on the
region of previous surgery.
 Based on the clinical context, ultrasound
may help avoid a misdiagnosis of an
intraabdominal malignant mass, abscess
and fecalith.
