Left Ventricle Intramuscular Haemangioma

Cardiac haemangiomas are rare cardiac tumours that are usually asymptomatic and detected incidentally while imaging the heart with echocardiogram. Cardiovascular magnetic resonance (CMR) is a non-ionising imaging modality that allows the diagnosis of cardiac haemangiomas prior to surgery. We report a 36-year old male patient who was referred to the Adult Cardiology Clinic at the Royal Hospital, Muscat, Oman, in 2006 with a history of a left ventricle mass detected on echocardiogram. Further assessment of the mass by CMR revealed that the mass within the left ventricle apical septum contained features that were consistent with a cardiac haemangioma. Due to the surgical risk of ventricular septal defect and the stability of the mass, the patient was managed conservatively and upon followup the patient’s condition remained stable.

Nasal Bridge Intramuscular Hemangioma

Intramuscular haemangioma (IMH) is a benign mesenchymal tumour. It appears as a deep, nontender mass within the soft tissue, particularly in the extremities. This tumour may not be obvious on clinical examination. Head and neck IMHs represent only 13.5% of the total IMHs. The most common site for a head and neck IMH is the masseter muscle, followed by trapezius, sternocleidomastoid, and very rarely temporalis muscle. We present a patient with left nasal bridge swelling which was excised and histologically confirmed as intramuscular hemangioma.

Intramuscular haemangioma of the tongue

Haemangiomas are one of the most common benign tumours. Clinicians come across haemangiomas of different subtypes at different locations in the body. They are often faced with the question of whether to treat them or leave it to the natural history of the disease. We present a case of the intramuscular variety of haemangioma found in the unusual location of the tongue in a 60-year-old woman. Fine needle aspiration was inconclusive and on magnetic resonance imaging, it mimicked a malignancy, which prompted treatment. We also review the unique pathology of this variety of haemangioma, which defines their treatment. The radiological attributes of the disease and recurrence rates of surgery are also discussed.

Intramuscular Haemangioma with Diagnostic Challenge: A Cause for Strange Pain in the Masseter Muscle

Intramuscular hemangiomas are unique vascular tumors which are benign in nature, most commonly occurring in the trunk and extremities. When present in head and neck, they most frequently involve the masseter and trapezius muscles, accounting for less than 1% of all hemangiomas. Most of these lesions present with pain and discomfort and some patients may demonstrate progressive enlargement. Due to their infrequency, deep location, and unfamiliar presentation, these lesions are seldom correctly diagnosed clinically. Our report is a clinically misdiagnosed case of a painful soft tissue mass in the right side masseteric region of a 23-year-old female patient, confirmed as intramuscular hemangioma based on imaging studies and histopathologic examination, treated by surgical excision which had no recurrence after a 3-year followup.
