Sporadic Multifocal Venous Malformations of the Head and Neck.
Objective. To report a case of unusually widespread sporadic venous malformations of the head and neck associated with normal D-dimer levels and, due to the protean clinical manifestations and increased risk of coagulopathy of these lesions, to review their diagnosis and clinical management. Case Report. A 25-year-old man presented with a one-year history of intermittent right-sided neck swelling and tongue swelling. Physical exam revealed additional lesions present throughout the head and neck. There was no family history suggestive of heritable vascular malformations. Radiographic imaging demonstrated 15 lesions located in various tissue layers consistent with venous malformations. A coagulation screen showed a normal prothrombin time, activated partial thromboplastin time, international normalized ratio, D-dimer level, and fibrinogen level. It was determined that the patient was not at increased risk for intraoperative coagulopathy and preoperative heparin administration would not be necessary. The patient's buccal and tongue lesions were subsequently excised with no complications. The patient also underwent sclerotherapy evaluation for his neck mass. Conclusion. This case describes a unique presentation of sporadic multifocal venous malformations. It also emphasizes the importance of prompt diagnosis and workup when multiple venous malformations are present to prevent morbidity during surgical excision secondary to intravascular coagulopathy.
