Ultrasound Pictures of “Diverticulitis”

Note: “Right-sided diverticulitis” of the sigmoid colon may be mistaken for
appendicitis.

Abnormal target pattern in the right lower quadrant: sigmoid
diverticulitis with peridiverticulitis. Differentiation is mainly required
from appendicitis with an incipient perityphlitic abscess.

we submit ultrasound pictures of diverticulitis as the below, please your see

Ultrasound Pictures Classification of Diverticulitis :
x Chronic, intermittent, secondary (diabetes mellitus, myxedema, amyloidosis, scleroderma, dermatomyositis, muscular dystrophy, endocrine disorders)
x Idiopathic
x Acute (Ogilvie syndrome) after a severe illness or surgical operation.

Clinical manifestations Diverticulitis: intermittent pain, abdominal distention, nausea, vomiting (suggests mechanical bowel obstruction); constipation, possible intermittent diarrhea with steatorrhea (in blind pouch syndrome due to intestinal bacterial overgrowth); malnutrition ranging to anorexia.

Diagnosis Diverticulitis

x History, clinical examination: Digital rectal examination is important (rectal
ampulla is filled with stool in pseudo-obstruction, empty with a true obstruction)
x Laboratory tests, including tests for endocrine disorders
x Sonography
x Endoscopic examination and biopsy (amyloidosis, muscular dystrophy); air
aspiration may also be therapeutic

“Ultrasound Pictures” Sonographic findings:
x Distended bowel loops with increased fluid content
x Small and large intestine may be affected
x Decreased peristalsis
x No obstruction of intestinal transit
x Bowel wall appears thinned
x The posterior walls of anterior bowel loops may not be visualized because of
dehiscence and intraluminal air.

Accuracy Ultrasound pictures of diagnosis of diagnosis: The sonographic findings are unequivocal, but the diagnosis remains uncertain because the cause cannot be determined. A stenosing lesion may be missed at ultrasound examination. Doubts are resolved by endoscopy and histologic evaluation of biopsy samples.

“Ultrasound Pictures” of Pseudo-obstruction: overdistended loops of colon with anterior intraluminal air (echogenic crescent). The plicae (arrows) and haustrations in this patient can still be identified.
