An magnetic resonance imagine (MRI) identified likely stress fracture of the second metatarsal base with a diffusely low T1 signal indicating hyperactive red marrow. Due to persistent pain, a follow-up MRI was ordered 6 months later and indicated serous atrophy of the bone marrow, prompting a further metabolic workup notable for triglycerides exceeding 4000 mg/dL and a hemoglobin A1c of 10.9%. This case highlights the manifestation of a rare congenital lipodystrophy that initially presented as a relatively classic stress fracture and metrorrhagia in a female athlete.
