Summary

Spontaneous pneumomediastinum rarely presents with temporal swelling. This case highlights an unusual association of cervical, facial, and retroperitoneal emphysema, emphasizing the need for careful observation.

Area of Science:

Thoracic surgery
Medical imaging
Emergency medicine

Background:

Spontaneous pneumomediastinum typically involves air dissection along bronchovascular shafts.
Air usually travels superiorly or inferiorly from ruptured alveoli.
Extensive subcutaneous emphysema with cervical and retroperitoneal involvement is uncommon.

Observation:

A rare case of spontaneous pneumomediastinum presenting with bilateral painless temporal swelling is described.
The patient exhibited cervical, facial, and retroperitoneal emphysema.
This specific combination of emphysema has not been previously reported in medical literature.

Findings:

The unusual presentation involved air dissecting to the temporal regions, a rare pathway for spontaneous pneumomediastinum.
The findings underscore the potential for varied and unexpected anatomical spread of air in spontaneous pneumomediastinum.
Diagnostic imaging confirmed the extensive emphysema, including the temporal regions.

Implications:

This case expands the known clinical presentations of spontaneous pneumomediastinum.
Physicians should consider rare anatomical distributions, such as temporal swelling, in diagnosing spontaneous pneumomediastinum.
Observation is crucial to monitor for and manage potentially life-threatening complications associated with extensive emphysema.
