It is well known that intramuscular hemangiomas are often accompanied by adipose tissue. However, reports on the presence of adipose tissue in intramuscular hemangiomas originating in the tongue are limited. Here, we present a case of an intramuscular hemangioma of the tongue with adipose tissue. A 33-year-old woman visited our hospital with complaints of tongue swelling and pain on swallowing. The mucosa of the tongue appeared normal in color, but there was significant swelling and tenderness on the dorsal surface. An occlusal X-ray revealed six calculus-like opacities within the tongue, while fat-suppressed T2-weighted MRI showed a diamond-shaped hyperintense lesion measuring 30 × 28 × 30 mm within the tongue muscle, raising suspicion of an intramuscular hemangioma. Contrast-enhanced MRI was performed to assess the lesion’s flow characteristics. The lesion involved the tongue muscle, bilateral pterygoid muscles, right temporal muscle, and the dorsal aspect of the right submandibular gland. These multiple lesions were considered slow-flow venous malformations. The patient wished to become pregnant and was concerned that hormonal changes might exacerbate the tongue hemangioma and cause pain, and so opted for aggressive treatment. A tongue-shortening procedure was performed via a median incision extending from the anterior part of the tongue to ensure adequate exposure. The lesion was excised from within the tongue. Oral intake was resumed on postoperative day 5, and active tongue movement training was initiated. The patient was able to eat normal meals and was discharged on postoperative day 10. Histopathological examination confirmed the diagnosis of an intramuscular hemangioma with mature adipose tissue.
