To emphasize the role of multidetector CT in the differential diagnosis
The pain in the left iliac fossa accompanied by fever is a frequent clinical problem originated by processes of varied etiology and prognosis. The first tendency is to suspect that it is diverticulitis because it is the most frequent pathology that this clinic gives,
but other pathologies must be taken into account. It is often difficult to arrive at adefinitive diagnosis based only on history and clinic tests,
requiring imaging studies in most cases. Taking into account the anatomical...
Findings and procedure details
NORMAL ANATOMY The left iliac fossa (LIF) is defined as the space between two imaginary lines,
a vertical one at the level of the left midclavicular line and a horizontal line between the two anterosuperior iliac spines. The left iliac fossais a crossroadin which coincide the gastrointestinal tract (sigmoid colon) the genitourinary tract (left ureter and left ovary in the female),
the iliac vessels and the muscles (iliopsoas). CLASSIFICATION OF THE PATHOLOGY OF THE LEFT ILIAC FOSSA. 1....
Acute diverticulitis is the second most frequent cause of acute abdominal pain and the most frequent cause of fever and pain in the left iliac fossa,
especially in middle-agedpatients.
Its main differential diagnosis should be performed with complicated sigmoid neoplasia,
however there are multiple pathologies that can occur with the same clinicand that the radiologist must know in order to make a more accurate diagnostic approach.
