Background:We present one of the first documented cases in the literature of an adult with Klippel-Trenaunay syndrome (KTS) with a large frontal osseous hemangioma.
Case Description:A 30-year-old male presented with a rapidly enlarging frontal skull lesion that had developed in only 3 months. Radiological investigation revealed a highly vascular lesion attached to the frontal bone. The lesion was surgically resected with the patient making complete recovery. Histopathology was consistent with an osseous hemangioma.
Conclusion:We report the clinical presentation and surgical management of a rare presentation of osseous hemangioma in a patient with KTS.

Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder characterized by the classic triad of capillary malformation, venous malformation, and limb overgrowth.[
A 30-year-old male with a known history of KTS presented with a rapidly enlarging subcutaneous central frontal mass, measuring 41 × 47 × 54 mm since its formation just 3 months earlier causing pain and an obvious cosmetic defect. The patient had no demonstrable neurological signs on examination with normal pre-operative laboratory studies, however, had previous episodes of significant hemorrhage arising from the lesion as a result of minor trauma.
Clinically, the patient was dysmorphic, most notably severe soft tissue overgrowth, bilateral lower limb lymphoedema, and cellulitis. Despite this, he had no history of other complications arising as a result of his KTS such as malignancy or peripheral hemangioma.
Radiological findings initially began with computed tomography angiogram, which revealed a destructive expansile arterially-enhancing lesion arising from the frontal bone. Heterogenous contrast enhancement on magnetic resonance imaging [
T1 weighted post contrast magnetic resonance imaging depicting the destructive nature and invasion of the vascular lesion; although it is closely associated with dura and superior saggital sinus, there is no evidence of parenchymal invasion. Digital Subtraction Cerebral Angiogram (right sided image) further characterizing the vascular lesion; arterial supply with fistulization from the ophthalmic artery and also some lesser arterial supply from the superficial temporal arteries bilaterally
Gross total resection consisted of a T-shaped incision followed by bilateral frontal craniectomies [
Postoperatively, the patient had a full recovery. Histopathological hemotoxylin and eosin stains revealed the lesion extending through bone, with a small foci of extramedullary hemopoiesis, consistent with hemangioma. There has been no evidence of recurrence 6 months post resection.
Since its description in the early 20th century, prevalence has remained uncommon.
To our knowledge, vascular lesions arising from the skull in patients with KTS have not been previously described in the literature. Previous reports do highlight the increased prevalence and wide variability of malignancy in patients with KTS peripherally and in the spine.[
Hemangioma are benign vascular tumors, most commonly seen in pediatric age groups.[
Intraoperatively, the tumor was seen to locally invade into calvaria with evidence of skull remodeling and destruction which is scarcely discussed as a characteristic of vascular hemangioma in past literature. Gross total resection is the gold standard of therapy and recommended by the authors. This minimizes recurrence and allows for tissue histopathological diagnosis in a syndrome known for predisposition to malignancy. The role for non-operative management in hemangioma including radiotherapy still exists.[
Postoperatively, the patient received regular follow-up with radiological screening for tumor recurrence.
We, as the authors would like to highlight this unique case of an intracranial osseous hemangioma with frontal skull based origin in a patient with KTS, a rare syndrome with a predisposition to malignancy. There are associated dangers and complexities for the surgeon involved in resection of these uncommon lesions.
