The symptoms of a cortical cyst, particularly a renal cortical cyst, often depend on its size, location, and whether it causes complications. Many simple cortical cysts are small and do not produce any symptoms at all. However, when symptoms do occur, they can include pain, obstruction of fluid flow, infection, or rupture.
Common Symptoms of a Cortical Cyst
When a cortical cyst grows large enough or is positioned in a way that interferes with bodily functions, it can manifest in various ways. Below is a summary of potential symptoms:
| Symptom | Description |
|---|---|
| Pain or Discomfort | Occurs when the cyst is large enough to press on nearby bones or other organs. |
| Obstructed Flow | The cyst can block the normal flow of blood or urine through the kidneys or the ureters. |
| Infection | An infected cyst can lead to symptoms like fever, localized pain, and tenderness. |
| Rupture | If a cyst bursts, it can cause sudden pain and may result in blood appearing in the urine (hematuria). |
Detailed Explanation of Symptoms
- Pain and Discomfort: As a cortical cyst expands, it can exert pressure on surrounding structures. This pressure can manifest as a dull ache or more significant discomfort in the flank (side), back, or abdomen, depending on the cyst's exact location.
- Obstruction of Flow: A strategically located or rapidly growing cyst can impede the flow of urine out of the kidney or interfere with blood flow within the kidney. Blockage of urine flow can lead to kidney swelling (hydronephrosis) and potentially impact kidney function over time.
- Infection: Although less common, a cortical cyst can become infected. When this happens, individuals may experience symptoms characteristic of an infection, such as:
- Fever
- Increased pain in the kidney area
- Tenderness to the touch over the affected kidney
- Rupture: In some cases, a cortical cyst can spontaneously rupture due to trauma or increased internal pressure. A ruptured cyst can cause acute, sharp pain. If the cyst ruptures into the urinary system, it can lead to hematuria, which is the presence of blood in the urine.
When to Seek Medical Attention
If you experience any of these symptoms, especially persistent pain, fever, or blood in your urine, it is important to consult a healthcare professional. They can accurately diagnose the cause of your symptoms and recommend appropriate management. Further information regarding kidney health can be found through resources such as the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
