A previously healthy 37-year-old man with an upper airway viral infection presented with a progressive onset of neck pain with odinophagia and pretracheal tenderness after repetitive sneezing efforts. Upon examination, cervical subcutaneous emphysema was the only finding. The chest radiograph confirmed the presence of pneumomediastinum. Cervical and chest CT scans performed during a Valsalva ma...

dysphagia over a 2-month period. Transnasal endoscopy with an ultrathin endoscope (Fujinon EG-530N; Fujinon, Wayne, New Jersey, USA) was used. An ulcerative tumor was found in the middle esophagus (●" Fig. 1), and the biopsy revealed squamous cell carcinoma. A feeding tube was placed over a guidewire. A chest computed tomography (CT) scan was performed the next day to evaluate the esophageal ca...

BACKGROUND Spontaneous pneumomediastinum is a rare and benign condition that generally occurs in young generations without any precipitating factor or underlying disease. The purpose of this study is to review our experience in dealing with this entity and detail a reasonable course of assessment and management. METHODS From December 1999 to May 2012, 32 spontaneous pneumomediastinum patients...

Hyperemesis gravidarum (HG) is a severe form of the more common nausea of early pregnancy. We report an unusual case of pneumomediastinum and bilatetral pneumothoraces presenting in the tenth week of pregnancy complicating HG.

Spontaneous pneumomediastinum associated with subcutaneous emphysema is a rare condition also known as Hamman's syndrome. It can also be seen postpartum. We present two cases of subcutaneous emphysema associated with childbirth in nulliparous women, both of which resolved spontaneously.

Management of tracheal tears can prove to be challenging in the perioperative setting. This is a rare condition that can be life threatening. Here, we present a case of seven-year-old boy involved in a high-speed motor vehicle collision. The child sustained multiple injuries including a near fatal head injury, multiple facial fractures, and a tracheal injury associated with pneumomediastinum. D...

INTRODUCTION We report a case of pseudomembranous tracheobronchitis caused by Aspergillus fumigatus 2 years after matched unrelated stem cell transplant. CLINICAL PICTURE The patient presented with dyspnoea and obstructive airway disease coinciding with the onset of chronic graft-versus-host disease (GVHD). Following treatment with higher immunosuppressive therapy for presumptive diagnosis of...

Air localized within the spinal canal is called pneumorrhachis. In the case of pneumorrhachis, air can be present in the extradural, the intradural, or the subarachnoid space of the spinal canal. The air within the soft tissue of the posterior mediastinum may dissect along fascial planes, through the intervertebral neural foramina, and into the extradural or the subarachnoid space. Nontraumatic...
