Summary
Computed tomography (CT) reveals unusual abdominal tuberculosis (TB) manifestations, including atypical ascites and adenopathy. Recognizing these diverse CT findings is crucial for accurate diagnosis and effective management of abdominal TB.
Area of Science:
- Radiology
- Infectious Diseases
- Oncology
Background:
- Abdominal tuberculosis (TB) diagnosis can be challenging, often requiring advanced imaging techniques.
- Computed tomography (CT) is a key modality for evaluating abdominal TB, but its characteristic findings are not always present.
Purpose of the Study:
- To update knowledge on abdominal TB presentation on CT.
- To identify and characterize the range and extent of abdominal involvement in proven TB cases.
- To compare observed CT findings with previously reported typical features.
Main Methods:
- Retrospective review of CT scans from 12 patients with confirmed abdominal tuberculosis.
- Analysis of the nature, range, and extent of abdominal involvement.
- Comparison of CT findings with existing literature.
Main Results:
- Mycobacterium tuberculosis was the causative agent in all cases.
- Low-density ascites and uncommon adenopathy patterns were observed.
- Typical abdominal TB findings were present in only 5 out of 12 patients.
- Unusual findings included pelvic, adrenal, splenic, and hepatic lesions, mimicking malignancy in 6 patients.
- Three patients had co-existing, previously undiagnosed thoracic TB.
Conclusions:
- Abdominal tuberculosis exhibits diverse and often atypical CT manifestations.
- Unusual findings can mimic malignancy, highlighting the need for increased radiologist awareness.
- Early recognition of these varied CT presentations is essential for optimal clinical management and avoiding misdiagnosis.
