September 2022 Medical Image of the Month: Epiglottic Calcification

Figure 1. Lateral (A) and frontal (B) topogram from a neck CT demonstrates linear calcifications in the expected location of the epiglottis (black arrows).  Sagittal multiplanar reconstructions demonstrate prominent calcification of the epiglottis (white arrow).

In consideration of dysphagia, most cases predominate in the oropharyngeal region with the remainder caused primary by esophageal causes. Lesser known and studied is the development of dysphagia and globus sensation from epiglottic pathology, namely epiglottic calcification. With less than a dozen published cases in literature, very little data exists on identification, diagnosis, and treatment of this known cause of morbidity. Here we present a case of oropharyngeal dysphagia arising from a rare cause, epiglottic calcification.

An 81-year-old man with a history of aortic stenosis and carotid artery stenosis presented with worsening dysphagia over the course of one month. The patient reported significant dysphagia, initially to solids and subsequently to liquids causing a weight loss of over 50 pounds. Physical exam of the oropharynx and neck were unremarkable. A bedside swallow evaluation suggested mildly decreased hyolaryngeal movement, but no other significant abnormalities.  A barium swallow study revealed incomplete epiglottic excursion during the pharyngeal phase of swallowing. The patient then underwent evaluation with a contrast-enhanced esophagogram, which showed severe esophageal dysmotility and gastroesophageal reflux. A CT of the neck demonstrated calcification of the epiglottis without epiglottal enlargement. ENT was consulted, the patient underwent flexible fiberoptic laryngoscopy and also EGD with biopsy.  No other esophageal or gastric pathology were identified other than the epiglottic calcification. As no effective treatment is known at this time, the patient was changed to a modified diet with ongoing speech and swallow therapy as an outpatient.

Epiglottic calcification is a rare cause of dysphagia that is poorly understood in its etiology, clinical course and outcome (1). This case demonstrates that despite consultant team recommendations, no clear evaluation pathway or treatment currently exists. Currently, diagnosis can be accomplished with radiologic evaluation along with exclusion of other causes; however, no definitive treatments are available for this rare condition. Although the condition itself is rare, epiglottic calcification should be considered when other more common causes of significant dysphagia are ruled out.

Medical Image of the Month: An Unexpected Cause of Chronic Cough

Figure 1. Axial image from a contrast-enhanced CT demonstrates a hollow, calcified structure in the bronchus intermedius with thickening suggesting inflammation in the surrounding bronchial wall (arrow).

 

Figure 2. Photograph of chicken bone fragment retrieved from bronchus intermedius during flexible bronchoscopy (A).  In retrospect, this fragment of bone is visible on the topogram from the chest CT (B) and is circled. Note the prominent notch that is visible on CT and on the actual bone fragment (arrowheads).

Sometimes it is as simple as it looks!  A previously healthy nonsmoking 40 years old man presented with a 7-month history of dry cough which was misdiagnosed as asthma. He had persistent cough despite appropriate asthma treatment including empiric PPIs. This patient had undergone extensive lab work up and evaluation; from negative viral and fungal panel, repeated pulmonary function tests which were within normal limits, chest x-rays, and CT scans which had shown small local calcification in the bronchus intermedius with significant thickening of the surrounding bronchial wall (Figure 1). The decision was made to proceed with flexible bronchoscopy, which yielded a chicken bone fragment with surrounding granulation tissue as shown in Figure 2A. In retrospect the bone is visible within the  bronchus intermedius on the topogram from the CT scan, see Figure 2B.

Foreign body aspiration in adults reported in low rates (0.66 per 100 000) (1). Despite being uncommon, neurological disorders, alcohol abuse, advanced age and altered level of consciousness all found to be the main underlying cause of foreign body aspiration in adults (2). Still, 10% of adult patients with foreign body aspiration have no known risk factors (3). Usually, diagnosis of foreign body aspiration in adults is straightforward only if the patient’s history involves aspiration or choking event. But, if the initial event goes unnoticed, the clinical picture maybe similar to obstructive lung diseases such as COPD or asthma.
