Differential Diagnosis for CT Abdomen Findings
Single Most Likely Diagnosis
- Mild ileus or nonspecific gastroenteritis: This is the most likely diagnosis given the presence of fluid in portions of the small bowel and colon without any evidence of obstruction, inflammation, or other specific causes.
Other Likely Diagnoses
- Diverticulosis: Although diverticulitis is ruled out, the presence of diverticulosis could be contributing to the patient's symptoms, especially if there is a history of diverticular disease.
- Gallbladder sludge or small gallstones: The possible faint density in the gallbladder could be indicative of sludge or small gallstones, which might be causing symptoms, although the absence of pericholecystic inflammatory changes and gallbladder wall thickening makes this less likely.
Do Not Miss Diagnoses
- Ovarian torsion or cyst rupture: Although the CT mentions multiple small follicles in the ovaries, it's crucial to consider ovarian torsion or cyst rupture, especially if the patient presents with acute abdominal pain. These conditions are emergencies and require prompt intervention.
- Cholecystitis: Despite the absence of pericholecystic inflammatory changes and gallbladder wall thickening, cholecystitis should be considered, especially if the patient has symptoms suggestive of gallbladder disease.
Rare Diagnoses
- Ovarian cystadenoma or other ovarian tumors: The presence of multiple small follicles could be indicative of an ovarian tumor, although this would be less likely without other specific findings on the CT.
- Intussusception: Although not directly suggested by the CT findings, intussusception could cause bowel obstruction and should be considered in the differential diagnosis, especially if the patient has symptoms of obstruction or abdominal pain.
