Fish bone as a foreign body is the most common food-associated foreign body in Asians as compared to meat impaction in the Western population, and the most common site is upper esophagus. The impaction of fish bones in the gastrointestinal tract during ingestion is a common complaint and can mimic acute coronary syndrome (ACS). A 45-year-old man presented to our emergency department with acute-onset retrosternal pain. Electrocardiogram, Troponin I, and two-dimensional-echocardiography were normal. Computed tomography of the chest showed a lodged fish bone tenting the upper esophagus, which was removed endoscopically. He was discharged on the 3rd day of the procedure. This case showed an unusual cause of acute chest pain which was initially suspected as ACS based on American College of Cardiology/American Heart Association guidelines. This case highlights the importance of thorough history taking and a need for high level of alertness in reaching the correct diagnosis.

| Introduction|| |
Fish bone foreign body (FFB) is the most common food-associated foreign body in Asians as compared to meat impaction in the Western population. The upper esophagus is the most common site of lodging of FFB. It has a wide range of clinical presentations. An FFB in the esophagus is a medical emergency and requires early treatment to prevent the complications. Here, we report a case of fish bone ingestion, which mimicked acute coronary syndrome (ACS).
| Case Report|| |
A 45-year-old man presented to the emergency department with a history of chest pain of 2 h duration. It was sharp, stabbing in character, and severe in intensity in the retrosternal area. It started soon after the intake of food. Pain radiated to the back and aggravated with swallowing and talking. He had a history of chronic ethanol consumption. There was no history of any other systemic illness or any similar illness in the past. On general physical examination, the patient was restless. His pulse was 110 beats/min and blood pressure was 110/80 mmHg. Cardiovascular and respiratory system examinations were unremarkable. Neurological and gastrointestinal system examination did not reveal any abnormality. His electrocardiogram showed only sinus tachycardia. Serial serum Troponin I levels were <10 ng/ml, which was also within the normal reference limit. Total leukocyte count was 7700 cells/cubic ml with a normal differential leukocyte count. Renal function and liver function tests were within normal limits. His two-dimensional-echocardiography was normal. In view of symptoms favoring ACS, he was initiated on treatment according to American College of cardiology/American Heart Association (ACC/AHA) guidelines for the management of chest pain. He was treated with antiplatelets, statins, and anti-anginal measures. However, 24 h after admission, the patient developed hypotension and developed breathlessness with fever. A possibility of aortic dissection was considered, and he underwent contrast-enhanced computed tomography of the chest. The CT ruled out aortic dissection. However, it revealed linear calcific densities in the upper esophagus in noncontrast phase of the study [Figure 1]. One of it was seen tenting the esophagus. On deep inquiry, he gave a history of consuming fish along with ethanol about 1 h prior to the onset of the chest pain. The diagnosis of fish bone ingestion mimicking ACS was made. He underwent flexible upper gastrointestinal endoscopy, and a fish bone was removed from the esophagus approximately 25 cm from the incisor. There was superficial ulceration of the esophageal mucosa [Figure 2]. The patient had an uneventful recovery with intravenous antibiotics and supportive measures. He was discharged on the 3rd day following removal of the fish bone.

| Discussion|| |
Among patients presenting to the emergency department with chest pain, 50% of them will be diagnosed with noncardiac chest pain. Esophageal chest pain remains one of the important causes. FFB ingestion is an important cause of foreign body in the oropharynx or esophagus. Its main complications are airway obstruction necessitating emergency resuscitation or esophageal injuries. Rarely, it can cause dreaded complications such as development of aorto-esophageal fistula.
Our patient presented to the emergency department with a history of acute-onset retrosternal chest pain, which initially mimicked ACS, and he was initiated on treatment according to ACC/AHA guidelines. Subsequently, he developed hypotension, which was most probably due to vagal plexus stimulation by the fish bone present in the esophagus. Patients with impacted fish bone can present with a wide range of manifestations from foreign body sensation to retrosternal pain. In the present case, the pain which increased on talking or swallowing was probably due to local injury to the throat by the fish bone. Our patient was treated with conventional treatment for ACS based on the ACC/AHA guidelines. However, when the clinical condition did not improve, other alternative possibilities that can cause similar symptoms were sought for. We evaluated for a possible aortic dissection which turned out to be negative. However, CT chest and a review of history helped in inching toward diagnosis. Hence, a thorough and detailed history taking is of utmost importance in making such diagnosis.
Plain radiography (both lateral and anteroposterior views) is the first screening investigation for FFB, however it has a low sensitivity of 32%. CT chest has a high sensitivity of 90%–100% and a specificity of 93.7%. Complications may increase if treatment is delayed beyond 24 h. Removal of the FFB by flexible endoscopy is the treatment of choice.
| Conclusion|| |
The lodgment of fish bone in the upper esophagus is a common entity. This case demonstrated an unusual cause of acute retrosternal pain in the form of FFB ingestion, which we initially treated as ACS based on ACC/AHA guidelines for the management of chest pain. Misdiagnosis can especially occur in circumstances where proper and relevant clinical history cannot be given by the patient. In such cases, CT may facilitate early diagnosis of FFB to avoid catastrophic outcomes. This case highlights the importance of thorough history taking and a need for high level of alertness in reaching the correct diagnosis.
