{{Short description|Spindle-like shape}} [[File:Spindle with cotton yarn.jpg|thumb|Spindle with yarn]] [[File:Lemon (geometry).png|thumb|A ''lemon'' in geometry]] {{Wiktionary|fusiform|fusiformis}} '''Fusiform''' (from Latin ''fusus'' ‘spindle’) means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel.
