This condition may arise from a number of causes i.e. both traumatic and non-traumatic. Diagnosis of the disease at an early stage and deliberate management can prevent the unwanted complications like femoral head collapse and severe arthritis and may save the bone. Although diagnosis of AVN is primarily dependent on radiological investigations, the incremental value and vital role of 99mTc-methylene diphosphonate (<sup>99m</sup>Tc-MDP) single-photon emission computed tomography (SPECT) over planar bone scintigraphy permits more accurate localization of lesions and provide pertinent information to recognize the disease at initial stage for better management. We present a case of unexplained low back pain in a young woman who was diagnosed as having avascular necrosis of both femoral heads by <sup>99m</sup>Tc-MDP bone scan incorporated with SPECT</p><p>Bangladesh J.
