Clinical question: Subdural hematoma. Signs and symptoms: Subdural hematoma. Nonenhanced CT of brain:There is no evidence of new bleed since prior exam. There is revisualization of patient's known right frontal and parietal subdural collection. This results in subtle mass effect and buckling of the cortex of right frontal and parietal lobes. In greatest dimension of subdural measures approximately 14 mm which is fairly similar to prior examination. Minimal discrepancy in measurements however could be secondary to slice positioning.No abnormality of brain parenchyma is detected. Cortical sulci and ventricular system are within normal range for patient's stated age. Burr hole is in the left frontal bone secondary to prior surgical intervention for drainage of subdural is again identified. A small left frontal -- temporal subdural is again identified. There is no evidence of interval change in the size or the extent of this lesion since prior study.Revisualization of bilateral extra conal well-demarcated high density lesions with no interval change. Findings could represent metastatic lesions. On prior examination the clinical date no included metastatic carcinoma. He above extraconal findings are not associated with any bony changes. Further evaluation with an MRI examination is recommended.
1.No evidence of new hemorrhage.2.Stable bilateral subdurals as detailed above.3.Stable bilateral extraconal retro-orbital masses as described.4.No detectable parenchymal abnormality on this non-infused CT of brain.
