Wegener's Granulomatosis: Are We Still Missing It?
Abstract:
We report the case of an 18-year-old female who was mis-diagnosed as a smear-negative pulmonary tuberculosis and advised standard antituberculosis treatment. She later presented with clinio-radiological worsening and thrombosis of superficial veins of the lower extremity. Cytoplasmic anti-neutrophil cytoplasmic antibody and computed tomography-guided lung biopsy confirmed the diagnosis of Wegener's granulomatosis. The rare association of superficial vein thrombosis with lung manifestation is highlighted here as also the need for a high index of clinical suspicion to avoid a missed or delayed diagnosis.
