Summary
This case study highlights intestinal tuberculosis mimicking malignancy. A patient presenting with abdominal pain and weight loss was diagnosed with Mycobacterium tuberculosis infection after initial suspicion of cancer.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Radiology
Background:
- Gastrointestinal symptoms like epigastric pain, constipation, and vomiting can be challenging to diagnose.
- Elevated tumor markers, such as CA19-9, can raise suspicion for malignancy.
Observation:
- A 32-year-old male presented with a 2-month history of epigastric pain, constipation, vomiting, and weight loss.
- Abdominal CT revealed proximal jejunal wall thickening.
- FDG-PET scan showed an FDG-avid lesion, and endoscopy identified mucosal fold thickening and skip ulcer lesions in the jejunum.
Findings:
- Biopsy cultures confirmed Mycobacterium tuberculosis infection.
- Pulmonary tuberculosis was ruled out during further evaluation.
Implications:
- Intestinal tuberculosis should be considered in the differential diagnosis of unexplained gastrointestinal symptoms and elevated tumor markers.
- This case underscores the importance of comprehensive diagnostic approaches, including microbiological analysis, to differentiate infectious from malignant conditions.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

01:29Positron Emission Tomography
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
