Description
A woman aged 31 years with no medical history was admitted to the intensive care unit for acute epiglottitis. For 4 days, she had been complaining of fever, intractable vomiting and increasing cervical pain treated with anti-inflammatory drugs.
The admission CT scan confirmed the diagnosis of acute epiglottitis associated with a parapharyngeal abscess (figure 1A). An intramural oesophageal dissection (IOD) was incidentally diagnosed (figure 1B), extending from the upper oesophageal sphincter to the lesser gastric curvature without any sign of mediastinitis (figure 1C and D). Initial panendoscopy revealed mucosal necrosis on the cervical oesophagus. Neither endoscopy nor an oral contrast-enhanced CT scan revealed any perforation. The parapharyngeal abscess was surgically drained and bacteriological culture revealed Streptococcus anginosus and anaerobic bacteria. A conservative treatment of the oesophagus proved effective with invasive mechanical ventilation, parenteral nutrition and appropriate antibiotherapy for 15 days. The patient was discharged home 21 days later after normalisation of both endoscopic and radiologic controls.
Cervical and thoracic contrast-enhanced CT scan. Acute epiglottitis was associated with a parapharyngeal abscess (panel A, black arrow) and a pneumatic false lumen revealing an extensive intramural oesophageal dissection (panel B, white arrow). The oesophageal dissection extended from the upper oesophageal sphincter to the lesser gastric curvature (panels C and D). No signs of mediastinitis or cellulitis were observed.
The present case describes an original presentation of IOD with a pneumatic false lumen complicating severe vomiting in a context of acute epiglottitis. IOD may have also been favoured by epiglottitis-induced local inflammation associated with the use of non-steroidal anti-inflammatory drugs.1 Although rare, IODs usually result in dissecting hematomas, caused by sudden pressure changes or direct traumatisms in elderly patients with comorbidities.2 Complications of IOD are rare and hence conservative management is the mainstay of treatment unless transmural perforation occurs.3
In summary, acute epiglottitis associated with intractable vomiting should lead to a search for IOD to adapt the monitoring.
Learning points
Epiglottitis may induce intractable vomiting.
Intramural oesophageal dissection should be searched in this context.
Conservative management can be considered.
