INTRODUCTION:

Tetanus is a disease that affects the nervous system and its clinical presentation is characterized by muscle spasms caused by the release of a neurotoxin produced by the formation of spores of the Clostridium tetani bacteria.

CASE DESCRIPTION:

We present the case of a 70-year-old man who after a fall, presented an injury to the ocular region. On admission, signs of local infection and involuntary contraction of the masseter muscles were evident, with impossibility of oral opening. Subsequently, he presented respiratory failure, generalized contractions and transfer to the intensive care unit, due to its similarity to convulsive events, pathology at the level of the central nervous system is suspected, for which it requires complementary studies and clinical analysis to rule it out.

DISCUSSION:

The diagnosis of tetanus is clinical, it is important to suspect it in patients with a history of skin lesions and inadequate immunization, due to its extensive clinical presentation, it can lead to confusion with other pathologies. Among the differential diagnoses are epileptic seizures, however, tetanus does not meet the semiological characteristics, does not compromise the state of consciousness and does not progress to status epilepticus, associated with the normality of complementary studies such as neuroimaging, cerebrospinal fluid study and registry electroencephalographic.

CONCLUSION:

Tetanus is a highly preventable disease and a diagnostic challenge for the health professional due to its wide onset of symptoms. That is why the diagnostic approach is important to recognize the differential diagnoses based on the clinical history, which allows an early and timely diagnosis.
