“…Our patient was previously diagnosed with nodular fasciitis, probably because the spindle cell component in MO is morphologically identical to nodular fasciitis. Laboratory and image studies have an important role in the diagnosis [ 7 ]. Imaging and pathology should be carefully observed to diagnose MO clearly while ruling out other soft tissue conditions such as sarcoma.…”

A woman in her 20s with a past medical history of surgical debulking of a right neck mass presented to the hospital for persistent and worsening right shoulder pain. The shoulder pain was associated with trismus and back and neck pain. A CT scan of the neck with contrast revealed post-surgical changes with increased heterotopic ossification throughout the surgical site extending to the supraclavicular soft tissues and the left sternocleidomastoid muscle, suggesting muscle ossification. A biopsy was performed, and the patient was diagnosed with myositis ossificans (MO). Initial treatment began with the administration of steroids and analgesics. She was scheduled for a follow-up with orthopedics, rheumatology, and genetics, but she was lost for follow-up. MO is a very rare medical condition usually associated with trauma, and in our patient, the symptoms started after a chiropractic adjustment.

“…Myositis ossificans (MOC) is non-neoplastic abnormal extraosseous bone formation [ 109 ]. MOC occurs usually in young adults and can be either traumatic, which is the most common, or non-traumatic in origin.…”

The paraspinal region encompasses all tissues around the spine. The regional anatomy is complex and includes the paraspinal muscles, spinal nerves, sympathetic chains, Batson’s venous plexus and a rich arterial network. A wide variety of pathologies can occur in the paraspinal region, originating either from paraspinal soft tissues or the vertebral column. The most common paraspinal benign neoplasms include lipomas, fibroblastic tumours and benign peripheral nerve sheath tumours. Tumour-like masses such as haematomas, extramedullary haematopoiesis or abscesses should be considered in patients with suggestive medical histories. Malignant neoplasms are less frequent than benign processes and include liposarcomas and undifferentiated sarcomas. Secondary and primary spinal tumours may present as midline expansile soft tissue masses invading the adjacent paraspinal region. Knowledge of the anatomy of the paraspinal region is of major importance since it allows understanding of the complex locoregional tumour spread that can occur via many adipose corridors, haematogenous pathways and direct contact. Paraspinal tumours can extend into other anatomical regions, such as the retroperitoneum, pleura, posterior mediastinum, intercostal space or extradural neural axis compartment. Imaging plays a crucial role in formulating a hypothesis regarding the aetiology of the mass and tumour staging, which informs preoperative planning. Understanding the complex relationship between the different elements and the imaging features of common paraspinal masses is fundamental to achieving a correct diagnosis and adequate patient management. This review gives an overview of the anatomy of the paraspinal region and describes imaging features of the main tumours and tumour-like lesions that occur in the region.

“…Males are affected more commonly (3:2) and its etiology is remains not clearly understood [4 , 5] . In most cases it occurs 4-12 weeks subsequent to a traumatic event, in other cases mechanical stress or minimal trauma can also be associated [6] . The most common location is the lower limb (73%) and within that region, the quadriceps muscle; areas prone to trauma such as the elbow and shoulder follow in frequency [6 , 7] .…”

The most common location is the lower limb (73%) and within that region, the quadriceps muscle; areas prone to trauma such as the elbow and shoulder follow in frequency [6 , 7] . MO is classified according to its presentation into 3 different types: myositis (fibrous) ossificans progressiva, traumatic, and circumscripta without history of trauma [8] .…”
