Abdominal tuberculosis is most commonly seen in the ileocecal region due to factors like stasis and abundant lymphoid tissue. It typically presents with abdominal pain and a mass in the right lower quadrant. Diagnosis involves imaging studies like ultrasound and CT scan showing thickened bowel walls and enlarged lymph nodes. Confirmation is by biopsy and PCR analysis. Treatment involves anti-tubercular drugs for 6-9 months along with surgery for complications like obstruction or hemorrhage. Prognosis is generally good with medical management but depends on early diagnosis and treatment.
