Rare case of adult-onset phalangeal microgeodic syndrome of the feet

Abstract

Phalangeal microgeodic syndrome (PMS) is a rare condition typically affecting children and is characterised by painful digits precipitated by cold temperatures. In medical literature, cases appear to be clustered in Japan. Adult-onset PMS is particularly rare and although imaging features are characteristic, it may go undiagnosed, as it is not commonly encountered. We present, to our knowledge, the fifth reported case in the literature of adult PMS, the second to affect the feet rather than hands, and the first in a Caucasian adult patient. This case report aims to raise awareness of this likely underdiagnosed condition to allow optimal management and avoidance of unnecessary diagnostic procedures.
