# A case of MRI-induced headache caused by an intracranial foreign body

## TL;DR

A man experienced MRI-induced headaches due to a metal nail in his brain from a past injury, highlighting the need for careful patient screening before MRI.

## Contribution

Highlights the risk of undetected intracranial foreign bodies during MRI and the importance of thorough patient assessment.

## Key findings

- A patient's headaches worsened during MRI due to an undetected intracranial nail.
- The foreign body was discovered via CT scan after MRI complications arose.
- Surgical removal was not feasible, emphasizing the need for caution in similar cases.

## Abstract

This case report delves into a unique occurrence of MRI-induced headaches attributed to an unsuspected intracranial foreign body. A male patient, presenting persistent headaches, experienced exacerbation of pain upon entering the MRI suite, hindering the imaging procedure. A subsequent head CT scan revealed a nail within the cranial cavity, stemming from a previous nail gun injury. Surgical removal was deemed unsafe, leading to continued observation. This case emphasizes the need for cautious exploration of abnormal symptoms in the MRI suite, urging healthcare professionals to consider potential foreign bodies. The incident underscores the risk of metallic fragments causing complications during MRI procedures and highlights the importance of thorough patient assessment before resorting to MRI imaging.
