@entity50 presenting as unilateral lobar haematomas with mass effect: an easily misdiagnosed cause of XXXX .

@entity558 @entity548 @entity5 @entity4 @entity772 @entity715 @entity50 @entity1779
@entity50 has protean clinical and radiological manifestations ranging from minimal effacement of sulci with no symptoms to severe @entity1779 associated with focal deficits, @entity772 and even death. An uncommon form of presentation is characterized by unilateral lobar @entity548 associated with extensive @entity4 and parenchymal distortion. In an acute presentation, this might resemble @entity548 into a @entity5 . In delayed presentations, the haematoma, being iso- or hypodense and showing peripheral ring-like enhancement, can @entity5 or infective processes. As this is an uncommon @entity558 , misdiagnosis is common with the potential for mismanagement and adverse outcomes. We present five such consecutive cases that were initially misdiagnosed as other entities. Each of these cases on closer inspection show features observed on CT and MRI that should have suggested a diagnosis of dural @entity50 . One of these cases progressed to not only extensively involve the superficial sinuses but also the deep veins, with a significant adverse outcome. The imaging features of this interesting variant of dural sinus @entity715 are reviewed. The haemodynamic basis for @entity548 and anatomical basis for the lateralization of the lesions are discussed.
