%X <B>UNASSIGNED: </B>Masquerade presentation of acute type B aortic dissections (TBAD) as acute limb ischaemia (ALI) is rare. Holistic clinical assessment, preferably with the help of scoring systems and timely computer tomographic angiogram (CTA), is needed for early diagnosis. Acute TBAD and its complications are increasingly treated with endovascular therapies.<BR><B>METHODS: </B>A 21-year-old male with poorly controlled essential hypertension was admitted with prominent clinical features of ALI. No clinical pointers of a TBAD were present. Doppler ultrasound revealed an arterial occlusive pattern, and an urgent surgical embolectomy was performed. On failure to retrieve any thrombi, a CTA was performed, and diagnosis of TBAD complicated with ALI was made. The limb was revascularised with guidewire directed aortic fenestration with angioplasty. TBAD was managed conservatively.<BR><B>UNASSIGNED: </B>We report a case of acute TBAD presented as isolated ALI, which was initially diagnosed and treated as an ALI unrelated to aortic dissection. TBAD with typical or atypical clinical features presented with ALI as a malperfusion syndrome is not uncommon. However, masquerade presentations of TBAD as ALI are rare in the literature. Endovascular fenestration with or without stenting has fewer neurological complications and long-term mortality than thoracic endovascular aortic repair (TEVAR). Moreover, they become convenient in resource-poor settings without dedicated aortic centres.<BR><B>CONCLUSIONS: </B>Masquerade presentation of TBAD should be recognised in the differential diagnosis of ALI. Timely CTA would prevent unnecessary interventions and help diagnose TBAD complicated with ALI. Despite their availability, outcomes will depend on proper patient selection for endovascular, surgical, and TEVAR options.
