Intestinal tuberculosis in a patient with end-stage renal disease on hemodialysis: A case report

We report an intestinal TB case with a clinical presentation similar to that of colon cancer in a patient with ESRD on hemodialysis. Patient concerns: A 49-year-old man presented with a 3-month history of general weakness and anorexia. He had been treated for stage 5 chronic kidney disease (CKD) due to diabetic nephropathy for the last 3 years. His blood urea nitrogen and serum creatinine levels were 96.9 and 8.1 mg/dL, respectively, at the time of admission; azotemia was accompanied by severe anemia, hypoalbuminemia, hyperkalemia, and metabolic acidosis. Hemodialysis was initiated for suspected exacerbation of uremia; however, intermittent fever, night sweats, and abdominal discomfort persisted. Diagnoses: Abdominal computed tomography (CT) and whole-body 18F-fluorodeoxyglucose positron emission tomography were indicative of ascending colon cancer with lymph node metastases. However, colonoscopy with biopsy revealed the formation of submucosal caseating granuloma and acid-fast bacillus. Interventions: We initiated quadruple therapy with isoniazid, rifampicin, pyrazinamide, and ethambutol. The patient continued the quadruple regimen for the first 2 months before switching to dual therapy and received anti-TB medications for a total of 12 months. Outcomes: After 9 months of standard anti-TB chemotherapy, polypoid residual lesions were noted during follow-up colonoscopy. Laparoscopy-assisted ileocecal resection was performed. No findings suggestive of recurrence o...
