A microcyst is a very small cyst, particularly when referring to breast cysts, that is too small to be felt during a physical examination.
Understanding Microcysts
Microcysts are generally discovered during imaging tests like mammograms or ultrasounds. They are distinguished from macrocysts, which are larger and can be felt upon palpation.
Key Characteristics of Microcysts
Here’s a breakdown of the key aspects of microcysts:
| Characteristic | Description |
|---|---|
| Size | Very small; too small to be felt during a physical exam. |
| Detection | Usually found during imaging tests like mammography or ultrasound. |
| Feeling | Not palpable (can't be felt) |
| Comparison | In contrast, macrocysts are larger and can be felt and are about 1-2 inches in diameter. |
Clinical Implications
- Detection Method: Since they are not palpable, microcysts are generally discovered incidentally when someone is undergoing breast imaging for other reasons.
- Monitoring: Once identified, microcysts may require periodic monitoring through follow-up imaging to observe any changes.
- Benign Nature: Most microcysts are benign and do not require treatment, but medical advice should be followed.
Example
- During a routine mammogram, a radiologist might detect tiny, fluid-filled sacs. These small sacs could be classified as microcysts since the patient does not feel them during self-examination.
In summary, a microcyst is a minute, usually fluid-filled sac that can be seen in imaging tests, and is too small to be detected through touch, unlike a macrocyst.
