RESUMO
Acute ischemic infarction in the territory of the artery of Percheron (AOP). AOP is a relatively uncommon neurovascular anatomical variant of the posterior circulation. It is a single arterial trunk supplying bilateral paramedian thalami and the rostral midbrain, a crucial structure responsible for regulation of alertness, consciousness, and sleep. The clinical presentation may deviate from the typical sensorimotor deficits seen with classical stroke syndromes. Without a high index of suspicion, AOP infarcts can be missed clinically and radiologically, thereby missing the crucial window of thrombolytic therapy. We discuss a case of a 60-year-old male, who was presented with acute onset altered sensorium due to AOP infarction and missed the opportunity for intravenous thrombolysis due to delayed diagnosis
RESUMO
Splenic infarction is an unusual diagnosis in infectious diseases. It is relatively more common in typhoid fever as opposed to nontyphoidal salmonellosis (NTS). A young male presenting with fever, abdominal pain, and tender hepatosplenomegaly, was investigated. Radiological tests showed the presence of areas of splenic infarction and his blood culture revealed the growth of NTS species. Only 5% of NTS infection present with extraintestinal manifestation such as splenic infarction, while the majority of the cases manifest as gastroenteritis
