Patients with brain tuberculomas are generally managed with 12-18 months of antituberculous treatment (ATT) with or without surgery. However, a subset of these patients may require ATT for longer periods. We studied the factors that were associated with the need for prolonged ATT (>24 months) in patients with brain tuberculomas. ⋯ Although 78% of brain tuberculomas resolve with 12-24 months of ATT, 22% required >24 months of ATT. Multiple tuberculomas had significant association with prolonged ATT, with a median duration of resolution of 36 months. Because tuberculomas >2.5 cm were likely to need longer duration of ATT, brain tuberculomas that require surgery should be excised totally or reduced in size to <2.5 cm to enable early resolution.

The relationship between superior cervical ganglia (SCG) ischemia due to bilateral common carotid artery ligation (BCCAL) and basilar artery (BA) reconfiguration was investigated. ⋯ A meaningful and paradoxic correlation was detected between the BA VDI values and degenerated neuron density of SCG after BCCAL. Although a low degenerated neuron density within SCG may provoke excessive sympathetic activity and prevent excessive BA dilatation with steno-occlusive carotid artery diseases, a high degenerated neuron density may cause dangerous vasodilatation of BA.
