This article deals with crystals in body fluids.
Crystals
Joint crystals
Types:[1]
- Gout = needle-shaped, negatively birefringent, yellow when aligned.
- Pseudogout = rhomboid-shaped, positively birefringent, blue when aligned.
Notes:
- Pseudogout also known as CPPD = calcium pyrophosphate dehydrogenase.
- Memory device: ABC+ = aligned blue is calcium & cuboid - positively birefringent.
Urine crystals
Types - morphology:
- Envelope shape (calcium oxalate).
- Diamond shape (uric acid).
- Coffin-lid shape (struvite).
- Hexagonal shape (cysteine).
Notes:
- Memory devices:
- Diamonds are see-through; ergo, uric acid stones not seen on KUB.
- Calcium oxalate = envelope, uric acid = diamond.
- Uric acid crystals: usually dissolve in formalin... but do not dissolve in alcohol.[2][3]
- Calcium oxalate crystals are seen in the context of ethylene glycol poisoning.[4]
