Case 1 (A–D), case 2 (E–G) and case 3 (H–K). A Left parietal lobar haemorrhage with adjacent SAH (straight arrow). The aetiology of the defect in the left frontal superior gyrus (triangle) remained elusive. B Lobar haemorrhage in the postcentral gyrus with adjacent SAH in the central sulcus (straight arrow). Note the left parietal defect (triangle). C Lobar haemorrhage in the left frontal superior gyrus and adjacent SAH (curved arrow) in the sulcus of the corpus callosum (coronal reconstruction). D Large right frontal lobar haemorrhage with mass effect, FLP (arrow) and SAH (curved arrow). FLP are extensions from the core haemorrhage which are longer than their width at the base of the haemorrhage. E Large right sided lobar haemorrhage with SAH (straight arrow), FLP (curved arrow) and subdural extension (triangle). F + G Large right sided lobar haemorrhage with SAH (F, straight arrow), FLP (G, curved arrow) and intraventricular extension (G, triangle). Note the trepanation (F, triangle). H–J Left temporal lobar haemorrhage with subdural (A, arrow) and subarachnoid extension (I, sagittal reconstruction, straight arrow) and FLP (J, sagittal reconstruction, curved arrow). K Large right frontal lobar haemorrhage with effect, SAH (straight arrow) and FLP (curved arrow). Note the trepanation (triangles)
