2013年4月21日 · Differentiating between SEs and SHs in patients with low platelet count on MRI is crucial as the former may just be secondary to IH and the latter due to a prior bleeding episode.

Acute CSF subdural hygromas had signal intensities identical to CSF without MR evidence of blood products. At surgery, clear fluid under pressure was found. MR imaging, with its unique ability to delineate the various phases of hemorrhage, is well suited to …

2 天之前 · MRI features most consistent with an arachnoid cyst of the middle cranial fossa ruptured into the subdural space with a subdural hygroma. Arachnoid cysts within the brain are common in children but its rupture within the subdural space is relati...

2013年4月21日 · The authors report a series of 80 cases of traumatic subdural hygroma and discuss the clinical and radiological features, management, surgical results, and pathogenesis.

2023年11月5日 · MRI (Magnetic Resonance Imaging): MRI provides even more detailed images of the brain and is often used when additional information is needed. It can show the extent of the hygroma and help in differentiating it from other conditions. The treatment of subdural hygroma depends on its size, symptoms, and the underlying cause.

An urgent repeated MRI lumbar spine revealed a dorsal intradural fluid collection (hygroma) at L1 displacing the cauda equina nerve roots anteriorly (Figure 2A), and a ventral intradural hygroma with conglomeration of the cauda equina nerve roots residing centrally within the …
