A Rare Cause of Thrombotic Thrombocytopenia Purpura- (TTP-)‎ Like Syndrome, Vitamin B12 Deficiency: Interpretation of Significant Pathological Findings

الملخص EN

Thrombotic thrombocytopenia purpura (TTP) is a hematological emergency that requires rapid assessment followed by prompt initiation of therapy due to high mortality associated with delayed treatment.

TTP has many causes including heritable syndromes, ADAMTS13 deficiency, and drugs-related etiologies.

Profound vitamin B12 deficiency can, in rare cases, mimic TTP in presentation, and since plasmapheresis can be of limited benefit, prompt diagnosis is necessary for accurate treatment with B12.

Therefore, careful analysis of all clinical signs, symptoms, and labs must be assessed.

We report a patient who presented with a diagnosis of TTP, and repeat assessment confirmed a diagnosis of sever vitamin B12 (B12) deficiency with pancytopenia who was appropriately treated with B12.
