An Unusual Case of Post-traumatic Intramuscular Organised Haematoma of the Left Hand

Abstract

An organised haematoma is a benign cystic lesion in which the haematoma is enclosed by a superficial fibrotic capsule. It is also referred to as chronic expanding haematoma or hematic cyst. Organised haematoma can be observed in various sites, but it is extremely rare to find it in an intramuscular location. This is a rare case of organised haematoma in the palm of the left hand of a 75- year-old female, which occurred after an accidental injury from broken bangles fifteen years ago. The swelling gradually increased in size and became painful over the years. A pre-operative Magnetic Resonance Image (MRI) revealed a well-defined, large soft tissue density lesion located in the subcutaneous plane of the interdigital space between the left thumb and index finger, extending into the volar and dorsal aspects of the hand. An incision was made on the skin over the swelling, followed by excision. The patient was discharged with a good post-operative outcome.
