Abstract:
The technetium-99m methylene diphosphonate (99mTc-MDP) whole-body bone scan along with single-photon emission computed tomography (SPECT/CT) can detect challenging soft tissue uptake patterns. We present a case of a 67-year-old female in whom the 99mTc-MDP scan, performed 3 hours after injection, revealed abnormal soft tissue uptake in the right thoracic region. No functioning right kidney was seen in the right lumbar region. Hybrid SPECT/CT revealed an ectopic right kidney in the subdiaphragmatic location, accompanied by gut loops and eventration of the right-sided diaphragm. This case underscores the value of SPECT/CT in identifying and characterizing unexpected anatomical abnormalities, such as ectopic kidneys.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
