Abstract:
Patients often present to the emergency department following a generalized tonic-clonic seizure, particularly of new onset. Complications associated with seizures usually arise from injuries sustained from loss of consciousness or during convulsive activity. This report describes a patient with an idiopathic seizure who developed postictal alveolar edema and delayed bilateral pneumothoraces and pneumomediastinum. A literature search revealed only 1 other case of this potentially life-threatening pulmonary complication from seizures.

Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Pneumothorax-II
Clinical Manifestations:
Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
