Pneumatosis intestinalis (PI), defined as intestinal intra- and extramural gas accumulation, is a rare radiographic finding in conditions of intestinal wall damage of varied etiology. Here, we report on a 56-year-old female with multiple myeloma who presented with undulating fever, fluctuating abdominal symptoms, and a distended abdomen 5 months after allogeneic hematopoietic stem cell transplantation (HSCT). Abdominal X-ray and CT scan documented PI with gas accumulation both in the intestinal and colonic bowel walls. Concurrently, thoracic CT revealed mediastinal and bihilar lymphadenopathy associated with bilateral pleural effusions. Microscopy of bronchoalveolar lavage fluid (BALF) revealed acid-fast bacilli, which were identified as Mycobacterium tuberculosis. Tuberculostatic treatment resulted in timely clinical improvement, a complete clearance of the radiological and clinical findings of PI, and the control of the tuberculosis (Tbc), determined by multiple negative BALF results. Taken together, PI occurred as the initial symptom of Tbc in an allogeneic stem cell recipient, achieving complete recovery by tuberculostatic treatment only.
