putamen

 [pu-ta´men]
the larger, darker, and more lateral part of the lentiform nucleus, separated from the lateral globus pallidus by the lateral medullary lamina.

pu·ta·men

(pū-tā'men), [TA]
The outer, larger, and darker gray of the three portions into which the lenticular nucleus is divided by laminae of white fibers; it is connected with the caudate nucleus by bridging bands of gray substance that penetrate the internal capsule. Its histologic structure is similar to that of the caudate nucleus together with which it composes the striatum.
See also: striate body, lenticular nucleus.
[L. that which falls off in pruning, fr. puto, to prune]

Caption: Figure 1: (a) DaTSCAN detected a slight decrease in tracer uptake in the left caudate nucleus, as well as reduced uptake in the putamina (more marked in the left).
He underwent MRI brain which showed bilaterally symmetrical subacute haemorrhage noted in the bilateral putamina. These appeared hyperintense on T1-weighted and isointense on T2-weighted images, which were associated with surrounding oedema.
(7,8) MRI demonstrates marked T2 hypointensity within the basal ganglia, with greatest involvement of the putamina and caudate nuclei.
