Conclusion
TCB is a diagnosis of exclusion. It is dramatic and rare complication of
cerebral and coronary angiography. Though controversial, neurotoxicity
of contrast medium and PRES have been suggested as the possible causes.
Independent risk factors include chronic hypertension, large dosage of
contrast medium and vertebral angiography. The condition shows complete
recovery within hours to days with no residual neurological deficit. It
requires supportive therapy; no evidence is available for the use of
steroids. Embolic infarction as a complication of angiography should be
ruled out with computed tomography, magnetic resonance and angiography
immediately. Due to the dramatic presentation of the index case,
radiologists and radiographers must be aware of TCB to avoid inutile
measures.
