DISSEMINATED TB IN AN IMMUNOCOMPETENT PATIENT

Abstract

TYPE: Case Report TOPIC: Chest Infections INTRODUCTION: Disseminated tuberculosis (TB) is a rare presentation, more common in patients with HIV, chronic liver disease or alcohol abuse and associated with high rates of treatment failure. CASE PRESENTATION: A 28 years-old male, with history of asthma, started complains of cough, sputum production and asthenia . Despite inhaled steroids, he continued to deteriorate. Skin ulcerations on the right wrist, elbow and leg appeared 4 months later. Fourteen months after the first symptoms, there was purulent drainage in the ulcers and a right knee edema which prevented the patient from walking. The patient presented to the hospital with extreme weight loss (20Kg). HIV screening was negative. CT scan with peri broncho-vascular opacities, tree-in-bud, cavitary lesions and pneumomediastinum. PCR for Mycobacterium tuberculosis was positive on sputum and knee pus. The patient started antibiotics (Clindamycin) and anti-TB drugs. A drain was placed on the right knee. Bone MRI revealed osteomyelitis in the knee, femur and cervical-dorsal spine, with need for surgical cleaning. DISCUSSION: A long evolution of symptoms was probably responsible for the exuberant presentation in this case of disseminated TB. The antibiotics and surgical strategies to treat the skin lesions were very challenging due to different microbiologic isolates and recurrence after drainage. The extension of lesions to the bone led to leg and arm movement impairment. Due to this, a multidisciplinary evaluation and decision to perform surgery were essential to prevent permanent disability. CONCLUSIONS: This case highlights the challenges in the management of thoracic complications of cavitary lesions, cutaneous ulceration and osteomyelitis due to TB. DISCLOSURE: Nothing to declare.
