A 22-year-old woman died after suffering a severe allergic reaction during a CT scan.

Law student Letícia Paul went into anaphylactic shock shortly after receiving the iodinated contrast.

She was intubated but passed away this week,less than 24 hours after what was meant to be a routine scan.

She had gone to the Hospital Regional Alto Vale in Rio do Sul,in Brazil’s southern state of Santa Catarina,for a routine scan due to a history of kidney stones.

In a statement,the hospital said: ‘We would like to take this opportunity to reaffirm our commitment to ethics,transparency,and patient safety,emphasising that all procedures are carried out in accordance with recommended clinical protocols.’

Letícia held a law degree and was pursuing postgraduate studies in Real Estate Law and Business.

Iodinated contrast is injected into a vein to make organs and tissues more visible during a CT scan.

It is widely used in medicine and is generally considered safe,but in rare cases it can trigger severe reactions.

Medical studies show that severe reactions to iodinated contrast are very rare,occurring in roughly one in 5,000 to one in 10,000 scans.

Healthcare facilities are typically prepared for such cases,but there are situations where even immediate medical care may not be enough.

Most people experience only mild symptoms,such as warmth,nausea,or itching after the IV is injected.

In 2023,a schoolgirl died from a suspected severe allergic reaction after drinking a hot chocolate at Costa Coffee in London.

The mother of Hannah Jacobs,13,who was intolerant to dairy products,fish and eggs since she was a toddler,ordered the hot drink thinking it had soya milk.

Hannah took a sip of the to-go drink in the dental practice’s waiting room while waiting for her appointment,only to realise it had dairy milk.

The mother had told the barista about her daughter’s dairy intolerance,the legal firm Leigh Day said.
