Recurrent diabetic muscle infarction, a rare complication of diabetes : a case report

الملخص EN

Diabetic muscle infarction is a rare complication of diabetes mellitus that presents as a localized, exquisitely painful swelling and limited range of motion of the involved extremity.

The onset is usually acute, persists for several weeks and resolves spontaneously over several weeks to months without the need for intervention.

However, as diabetes mellitus is an immunocompromised state and any painful swelling in the limbs is often taken as infectious in aetiology, the patient is inadvertently investigated with invasive procedures and is started on unnecessary antibiotics, adding to the burden of management.

Keeping in view the low threshold for starting antibiotics in painful limb swelling in diabetes mellitus in our setting, we hereby describe a case of recurrent painful diabetic muscle infarction, first involving the right upper and later the right lower limb, managed with physical rest and analgesics.

This case emphasizes that the treating physician keep this rare complication of diabetes mellitus in consideration in the respective clinical scenario and adopt a less aggressive (a noninvasive method like ultrasound) rather than a more aggressive (an invasive method like muscle biopsy) approach in diagnosis and take a similar approach towards management.
