Spontaneous subdural haematoma in a healthy young male

Spontaneous Recurrent Chronic Subdural Hematoma in a Young Woman

“…Wang et al 6 reported an interesting case Letter to the Editor of spontaneous CSH in a flute trainer, which they thought to be caused by increased intravenous pressure induced by repeated blowing of air (Valsalva's maneuver). Similar role of repeated Valsalva's maneuver in causing subdural hematoma has been reported by Brennan et al 10 in a marathon runner and Jacome and Yanez 11 in a heavyweight lifter. Intracranial hypotension secondary to systemic hypotension or exercise can cause spontaneous subdural hematoma.…”

Spontaneous Chronic Subdural Hematoma in an Adolescent Girl

“…In the absence of trauma and any predisposing conditions, subdural bleeding might instead result from a sudden increase in intravenous pressure, which can occur when forcible exhalation occurs against a closed glottis, for example, during the Valsalva maneuver or during coughing or defecation, but also while blowing. Brennan et al2) presented a spontaneous subdural hematoma in a 37-year-old male marathon runner. They supposed that weight training, which could potentially cause subdural hematoma throught generation of valsalva maneuver.…”

Spontaneous subdural haemorrhage from an arachnoid cyst: a case report and literature review

“…5,10 Spontaneous SDH could arise following a Valsalva manoeuvre on coughing, straining or weight training, 11,12 and in association with intracranial hypotension sec- ondary to CSF leak or shunt over drainage, exercise, 13,14 or dehydration. 15 We found no direct evidence for the above in our patient. Arachnoid cysts are a common incidental finding on imaging in adults.…”
