Gadolinium enhanced T1 weighted (1a) Sagittal (1b) Axial and (1c) coronal magnetic resonance imaging (MRI) images showed diffuse and linear enhancement of the meninges along the entire cerebral convexities (thick arrow) and the inter hemispheric fissure (thin arrow)

A Magnetic resonance imaging (MRI) brain with gadolinium contrast was performed, which showed diffuse pachymeningeal enhancement [Figure 1].
Anterior and posterior images of 99m Technetium Diethylenetriaminepenta acetic acid cisternography in a patient of spontaneous intracranial hypotension. (2a) 1 h anterior view of lumbar region showed early visualization of both kidneys and bladder (thin arrows). (2b) 2 h anterior view and (2c) 2 h posterior view images showed mild extra-dural radiotracer accumulation in the region of right upper thoracic spine (dotted arrows). (2d) 24 h posterior view image showed inadequate ascent of tracer over the higher cerebral convexities (notched arrow)

There was early visualization of the kidneys and bladder on the 1 h delayed image [Figure 2]. Subtle extra-dural tracer accumulation of radiotracer was noted in the region of upper thoracic spine on the right side in the 2 h anterior and posterior delayed images [Figure 2]. Inadequate ascent of tracer over the higher cerebral convexities was noted in the 24 h delayed image [Figure 2].
