A 55-year-old man complained to his internist of pain over the lateral
aspect of his left iliac crest. A 99mTc methylene diphosphate bone
scan showed increased activity in this area (Figs.
3A and
3B) although no corresponding
bone or soft-tissue abnormality could be detected on radiographs
(Fig. 3C). Seeing the patient
dressed for work, the physician noticed that a beeper was belt-mounted
directly over the point of pain and increased radionuclide uptake. He
recommended that the beeper be relocated. At follow-up 13 months later, the
pain was gone, and the repeat bone scan showed almost total resolution of the
previous area of increased activity.

Follow-up 99mTc methylene diphosphate bone scan obtained 13 months
later in now asymptomatic patient shows virtually complete resolution of
previous focus of increased activity.

We posit that the pain resulted from the intermittent or constant pressure
of the beeper against the insertion of the external oblique muscle at the
iliac crest, thus producing tendinitis, peritendinitis, or bursitis somewhat
similar to that produced in the "pump bump" seen in Haglund's
disease [1].
