Objective:
Abdominal tuberculosis (TB) is a relatively rare disease in most of Europe and the typical clinical and sonographic findings in this setting have not been studied. We aimed to define sonographic findings that should alert an examiner to the possibility of abdominal TB in a low endemic region.
Methods:
Case records of 17 patients with proven (n = 11) or highly likely (n = 6) abdominal TB detected in the gastrointestinal ultrasound unit at a German tertiary care center in 2003-2013 were analyzed retrospectively. Findings were compared with reported series from high-prevalence regions.
Results:
While 76% of patients had an immigrant background, only 35% had a condition associated with immunosuppression. Lymphadenopathy was present in all cases of abdominal TB, while it was absent in 28% of patients from a control group with proven abdominal sarcoidosis. Moreover, retroperitoneal lymphadenopathy was significantly more common in TB. Other findings in patients with abdominal TB in descending order of frequency were ascites, altered hepatic texture, splenomegaly, splenic lesions, peritoneal thickening, intestinal wall lesions, hepatic lesions and hepatomegaly. 76% of abdominal TB patients had 2 or more pathological findings.
Conclusions:
Multiple pathological intra-abdominal findings including lymphadenopathy should alert the examiner to the possibility of abdominal TB.

01:20Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

01:25Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
