Intercostal Muscle Cavernous Haemangioma: A Chest Wall Pandora’s Box
Intercostal muscle cavernous hemangioma
KeywordsCavernous haemangioma, chest wall tumour, histopathology, surgery
Background: Haemangiomas are uncommon chest wall tumours arising outside the rib cage. Their occurrence in intercostal muscle is extremely rare.
Aim: We describe a case of intercostal muscle cavernous haemangioma as a differential diagnosis for chest wall swelling.
Case description: We describe an 18-year-old male patient with an asymptomatic left-sided chest wall swelling. Contrast-enhanced computed tomography revealed a well-defined homogenously non-enhancing mass lesion arising from the seventh intercostal muscle with differential diagnoses of various chest wall tumours. Clinical presentation and imaging findings were inconclusive, but histopathological examination following excision biopsy revealed a cavernous haemangioma. The present case emphasizes the importance of histopathological diagnosis when clinical and radiological examination is inconclusive. Hence, it is necessary to consider intercostal muscle haemangiomas as a differential diagnosis for chest wall tumours in the absence of a feeding vessel.
Conclusion: Despite its rare occurrence, intercostal muscle haemangioma must be considered as a differential diagnosis in chest wall tumours even in the absence of a feeding vessel. We believe that histopathology can provide a definitive diagnosis when most investigative procedures are inconclusive.
