Pneumatocele of the Cranium

Thinking outside the cranium

Introduction Cerebral toxoplasmosis is a leading cause of central nervous system (CNS) lesions in severely immunocompromised human immunodeficiency virus+ (HIV+) patients who are seropositive for the parasite and have not received effective chemoprophylaxis. A 48-year-old HIV+ woman presented to our emergency room with seizure and decreased level of consciousness. She had developed fever, produ...

Cranium Bifidum

An infant girl was referred for assessment and management of a large frontal skull defect. She was born, after an uneventful pregnancy, by caesarian section to a 36-year-old mother (G1P1). The procedure was performed electively for a breech presentation. Her antenatal ultrasound had shown no specific abnormalities. The attending pediatrician immediately noted a large bi-frontal (but predominant...

tocele in the left upper lobe. A linear air pocket in the soft tissue of the left upper hemithorax was also noted ( fig. 1 c). CT revealed a 15 ! 6 cm cavitary lesion in the left upper lobe extending and communicating with the chest wall through a fistulous tract without pneumothorax or mediastinal emphysema ( fig. 2 ). The subcutaneous air pocket had been noted on the patient’s examination 4 y...

A study of the rhythmic motions of the Cranium living cranium

The hypothesis of inherent motility of the cranium has been supported by palpation of the living head. The hypothesis that a rhythm synchronous with the arterial pulse and another associated with thoracic respiration might be detected is in accord with known physiologic phenomena. The report of a third palpable rhythm, slower than either pulse or respiration, required more study. This article r...
