Intrathoracic kidney, an extremely rare form of renal ectopia, was diagnosed in a 62-year-old man presenting with urinary issues. This case highlights the importance of advanced imaging in identifying congenital anomalies.
Area of Science:
- Medical Imaging
- Urology
- Congenital Anomalies
Background:
- Ectopic kidney is a recognized congenital anomaly where the kidney is not in its usual anatomical location.
- Renal ectopia encompasses various conditions, including the rare intrathoracic kidney, where the kidney resides within the chest cavity.
Observation:
- A 62-year-old male patient presented with urinary problems requiring investigation.
- Initial ultrasonography suggested the presence of an intrathoracic kidney.
- A computed tomography (CT) scan confirmed the diagnosis of intrathoracic kidney.
Findings:
- The case successfully diagnosed an extremely rare instance of intrathoracic kidney using diagnostic imaging.
- Ultrasonography and CT scan were pivotal in confirming the ectopic renal location.
Implications:
- This case underscores the diagnostic utility of imaging modalities like ultrasonography and CT in identifying rare congenital renal anomalies.
- Understanding and reporting such rare cases contribute to the broader medical knowledge base for renal ectopia.
- Early and accurate diagnosis of intrathoracic kidney is crucial for appropriate patient management and further research.

Internal Anatomy of the Kidney
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
