“…Literature reports only one case of accidental ingestion of a SIM card by Dixit et al in which no foreign body was found on examination and patient was advised to return if he further develops vomiting or abdominal pain. 1 Laryngeal foreign body is encountered less commonly than bronchial foreign body, but is potentially more dangerous. Diagnosis is made by clinical and radiological examination.…”

“…Accidental ingestion of foreign bodies in the pediatric population are usually small pieces from toys or other household objects and subsequent emergency department attendance is a common occurrence. 1 The technical improvements has facilitated the retrieval of foreign bodies by utilizing various advancements such as rod lens, video endoscopy, a broad range of a variety of sized forceps and safer anaesthesia. Despite of these advancements, more than 3000 deaths occur per year because of foreign bodies and an untold number of patients survive with variable sequelae.…”

Background. Foreign body ingestion typically affects children or adults with mental conditions. SIM (subscriber identity module) card ingestion is extremely rare. As their particularly X-Ray dense metal parts are sized about 9 × 12 mm × 50-80 μ, they can be difficult to capture on plain radiographs. We were asked by investigative authorities to point out the best method to document intentionally swallowed SIM cards. Method and material. A case of a 23 year old female who had swallowed a SIM card when she was arrested for murder was followed up with four abdomen radiographs and CT (computed tomography) of the abdomen. Experimentally, SIM cards were examined in CT. SIM card object contrast against surrounding background was quantified through CNR (contrast-to-noise ratio). Results. SIM card orientation perpendicular to plain film X-Ray beams resulted in relatively low CNR values of 1.6-2.5. SIM cards in CT scans yielded considerably better CNR values exceeding 9. Discussion. While plain abdomen radiographs have a lower X-Ray dose than abdomen CT scans, more frequent possibly negative results may lead to repetitive exposure. We recommend to consider drug trafficking as possible problem in conjunction with any observed SIM card swallowing, particularly in context of police arrests or a suspect's detention. We recommend to consider CT of the abdomen, if possible with a low dose, rather than plain abdomen radiographs.
