1.- Update current knowledge on the capacity of radiological techniques to differentiate sigmoiditis/acute diverticulitis from colon cancer.
2.- Describe and illustrate the orienting CT findings (computed tomography).
Individuals living in industrialized countries face an approximately 60% risk of developing colon diverticula (1).
Acute diverticulitis is one of the causes of hospitalization,
affecting up to 25% of patients with diverticulosis (2,
The assessment and management of acute diverticulitis have evolved steadily in recent decades.
There has recently been a significant increase in the use of CT to confirm the acute diverticulitis diagnosis,
with a trend toward conservative treatment over surgical resection (4,
Surgery is commonly reserved for cases of Hinchey III/IV...
Findings and procedure details
Current internationally-accepted directives recommend routine colonoscopy following an acute episode to confirm the diagnosis and rule out malignancy,
given the frequent similarities between the clinical-radiological presentations of acute diverticulitis and colon cancer.
This recommendation is based on studies performed prior to the use of high-quality CT,
in cases in which evidence of low performance of CT orient a diagnosis of malignancy or benignancy was found.
One example of the scenario described are the results published by Chintapalli et al (6).
They performed a retrospective analysis...
It is possible to orient the diagnosis of the inflammatory or neoplastic origin of a colon segment affected by sigmoiditis/acute diverticulitis with high reliability using radiological tests.
Their performance appears to be directly related with the use of CT of greater quality,
and the consolidation of recently-developed techniques with promising results such as the PCT,
CCT and the use of T2- weighted MRI and diffusion-weighted MRI.
the evidence is still too limited for radiological tests to replace the current routine usage of the colonoscopy...
