CLINICAL FEATURES : 6 months male baby
presented with cry.
SONOGRAPHIC
FINDINGS : Mass with hypoechoic rim with central
echogenicity. (pseudokidney sign) at transverse, desending
colon, rectal
regions.
DIAGNOSIS : Ileo-colic
intussusception is per -operative diagnosis.
DISCUSSION
: Intussuscetion is the most common cause of small bowel obstruction
in chindren between the ages 6 months and 4years. Clinical
findings of crampy,intermittent abdominalpain, vomitings and current
jelly stools are classic nature.Resent studies shows that ultrasound
is highly sensitive and specific for the diagnosis of
intussuception.
Sonographically intussusception appear as an oval, hypoechoic with
central bright echoes on longitudinal imaging(i.e. Pseudokidney sign)
and target confugaration on cross sectional image.Hypoechoic rim
represent s the edematous wall of the intussusceptum and central
echogenicity represents compressed mesentary , mucosaand intestinal
contents.Large amount of fluid in peritonium suggestive of bowel
perferation.(Small amount of ascitis may present in peritonium even
without peforation.)
Role of sonography is
to establish diagnosis , to detect complecations, to guide the
mode of treatment, to assess the response for non-surgecal
treatment, ? to assess the risk of perforation by color doppler.
