**Core Concept**
Steroids are used in tuberculosis (TB) to modulate the body's immune response and reduce inflammation. They are particularly useful in extrapulmonary TB, where the infection is located outside the lungs. Steroids are used to prevent tissue damage and improve outcomes in conditions like TB meningitis and pericarditis.

**Why the Correct Answer is Right**
Ileo-caecal tuberculosis is a type of intestinal TB that typically presents with abdominal pain, diarrhea, and weight loss. In this form of TB, the primary concern is the destruction of the intestinal mucosa and the potential for intestinal obstruction or perforation. Steroids are not typically used in the treatment of intestinal TB as they can worsen the disease by suppressing the immune system and allowing the TB bacilli to multiply and cause more damage.

**Why Each Wrong Option is Incorrect**
**Option A:** TB meningitis is a serious and life-threatening form of extrapulmonary TB that requires prompt treatment with steroids to reduce inflammation and prevent long-term neurological damage.
**Option B:** Pericarditis due to TB is a medical emergency that requires the use of steroids to reduce inflammation and prevent cardiac tamponade.
**Option D:** Adrenal involvement in TB can lead to adrenal insufficiency, which is a medical emergency that requires the use of steroids to replace deficient hormones.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that steroids are not a substitute for antitubercular therapy in any form of TB. They are used adjunctively to modulate the immune response and prevent tissue damage, but they do not kill the TB bacilli.

**✓ Correct Answer: C. Ileo-caecal tuberculosis**
