Thrombotic thrombocytopenic purpura is an acute syndrome with abnormalities in multiple organ systems, which becomes manifest with
microangiopathic hemolytic anemia and
thrombocytopenia. The hereditary or acquired deficiency of ADAMTS-13 activity leads to an excess of high molecular weight
von Willebrand factor multimers in plasma, leading to platelet aggregation and diffuse intravascular
thrombus formation, resulting in
thrombotic thrombocytopenic purpura. Thrombotic lesions occurring in
TTP leads to
ischemia and convulsion. Depending on the properties of the bony tissue, fractures are divided into three groups as traumatic, pathological, and
stress fractures. A
pathologic fracture is a
broken bone caused by disease leading to weakness of the bone. This process is most commonly due to
osteoporosis, but may also be due to other pathologies such as
cancer,
infections, inherited bone disorders, or a
bone cyst. We herein report a case with a
pathologic fracture due to convulsion secondary to thrombotic thrombocytopenic pupura. Thrombotic lesions occurring in
TTP may lead to
ischemia and convulsion, as in our patient and
pathological fractures presented in our case report may occur as a result of severe muscle contractions associated with convulsive activity. Thrombotic thrombocytopenic pupura is a disease that involves many organ systems and thus may have a very wide spectrum of clinical presentations.
