Abstract :
We presented a 30 year-old woman presented with symmetrical swelling of the lower limbs since 5 years ago with sparing of
the feet. She was highly suspicious of having lipoedema and was referred for lower limb lymphoscintigraphy to rule out
possible lymphedema. Lymphoscintigraphy images showed asymmetrical injection sites and unusually high liver and spleen
uptake. Inguinal nodes was not visualized on the right side. With the suspicion of inadvertent intra-vascular injection, another
injection was done on the right side. Repeated imaging showed inguinal nodes with normal uptake. In conclusion, in case of
any suspicion of intra-vascular injection of the radiotracer in limb lymphoscintigraphy, re-injection of the tracer can be of
especial use to avoid false positive results.
