Chronic subdural hematoma (CSDH), located between the dura mater and the arachnoid and usually characterized by a well-vascularized external capsule (HEM), has a higher incidence in male patients with elevated urinary estrogens than in female patients. In an attempt to increase our understanding of the physiopathogenesis of CSDH, total estrogen receptor (ER) was measured in HEM specimens from four male patients by a sodium thiocyanate exchange assay and cytosol progesterone receptor (PRc) in three specimens by a dextran-coated charcoal adsorption assay. Although no nuclear ER could be detected, ERc and PRc were found in all three specimens examined. The presence of ER in a mesenchymal tissue like HEM could suggest that, in addition to inducing vascular changes, estrogens might act directly on HEM through a receptor-mediated mechanism more pronounced in men than in women, whose vascular network is adapted to high estrogen values. |
