A 38-year-old male was diagnosed with aortoiliac aneurysm while evaluating for new-onset hypertension. On further workup, the cause was identified as tubercular aortoiliac aneurysm. His aneurysm had stormy course and disseminated further while ongoing antitubercular therapy with multiple episodes of aneurysmal rupture and endovascular interventions. Management of this case was complicated with several other rarer entities, such as haemophagocytosis and thrombotic microangiopathy with disseminated intravascular coagulation resistant to steroids and plasmapheresis, within a span of few weeks. Moreover, first-line antitubercular therapy had to be regularly modified in view of emerging complications. While case reports for each individual entity exists in literature, this is the first case to the best of our knowledge where such varied complications were present in a patient of tubercular mycotic aneurysm.
