“…Treatment of choice is complete surgical excision and reoccurrences are exceptional. 1,2,3 The myxoma can present as an isolated lesion or together with fibrous dysplasia or Albright syndrome. 3,4 The presence of multiple lesions, which are also associated with fibrous dysplasia, is named as Mazabraud's syndrome.…”

“… 1 In light of the literature available to date, intramuscular myxomas most commonly occur in the muscles of thigh, with less common sites being the shoulder, buttocks, lower leg, and upper arm. 1 , 2 Intramuscular myxoma share the same anatomical location as fibrous dysplasia, which is known as Mazabraud’s syndrome. 5 Diagnosis can be made with good history and examination; however, a robust diagnosis can only be made upon histological examination.…”

Intramuscular Myxomas are rare benign soft tissue tumors which usually occur between the ages 40 and 70 years and are more common among females. A thorough history and examination can help with diagnosis and it can be confirmed via histological examination. A 40-year-old female presented with a swelling in the medial aspect of right thigh which measured about 5 × 5 cm. Ultrasound, magnetic resonance imaging, and histopathology examination confirmed the diagnosis and a complete surgical resection was performed to remove the mass. Intramuscular myxoma should be included in differential diagnosis of sarcomas, hemangioma, desmoid tumor, clear cell sarcoma, and lipomas. Magnetic resonance imaging should be the investigation of choice, and histopathology remains the gold standard of investigation. Complete surgical excision with negative margins is the treatment of choice.

“…Imaging techniques may include X-ray, ultrasound, computed tomography (CT scan) or magnetic resonance imaging (MRI). X-ray examinations may be normal or show a non-specific intramuscular mass that rarely contains calcifications [ 4 , 12 ]. On ultrasound images, an IM typically appears as a well-circumscribed, hypoechogenic or heteroechogenic mass, sometimes with a cystic component [ 1 , 11 ].…”

“…The tumour should be differentiated from other benign lesions (such as lipoma, fibroma, haemangioma, schwannoma or cystic non-neoplastic lesions) and malignant tumours (such as myxoid liposarcoma, myxoid chondrosarcoma, fibrosarcoma or mucinous adenosarcoma metastases) [ 3–5 , 12 , 13 ].…”

“…They are often solitary, however, multiple lesions are seen in syndromes such as Mazabrauds which consists of polyostotic fibrous dysplasia and multiple intramuscular myxomas. The lesions are hypointense on T1 and hyperintense on T2 weighted sequences (19). Intramuscular haemangiomas are common in the general population.…”

Introduction. Referred pain along the deltoid muscle is a common presentation of patients with shoulder pathology. Intramuscular lesions involving the deltoid muscle are often identified on routine ultrasound or magnetic resonance imaging of the shoulder. The aim of this retrospective study is to review deltoid lesions identified at our institution and to provide a diagnostic approach to aid their management. Methods. A retrospective study of our orthopaedic oncology database was performed to identify lesions referred to our institution between June 2007 and June 2018. Relevant imaging was reviewed on our picture archiving and communication system (PACS). Patient demographics, anatomical extent and MRI characteristics of the lesions were assessed along with histological correlation. Results. 91 patients were included in the study of which 42 (46%) were male and 49 (54%) were female with an age range of 22-88 years. 8 patients were under 40 years and one low grade fibromyxoid sarcoma was identified in this age group. In the over 40 year cohort, the commonest lesion was a lipoma and malignant lesion was identified in 13 (16%) patients. The vast majority of lesions were confined to a single deltoid muscle compartment. 4 lesions involved more than one compartment, all of which were malignant. Conclusions. Deltoid lesions in patients under 40 years are highly likely to be benign whereas the probability of malignancy increases in patients over 40 years of age. Lesions involving more than one muscle compartment are likely to be malignant.
