47-year-old man with intracortical hemangioma. Lateral radiograph of the right lower leg shows an expansile, lytic lesion with geographic border at the anterolateral cortex of the distal tibial diaphysis. There are internal lattice-like, vertically oriented striations and trabeculae with a minimal, thin, sclerotic rim and cortical erosion.

Radiograph of the right lower leg revealed an expansile and geographic lytic lesion at the anterolateral cortex of the distal tibial diaphysis (Fig. 1).
47-year-old man with intracortical hemangioma. MRI of the right lower leg. (A) Axial T1-weighted image shows intracortical mass with low signal intensity. (B) Axial T2- weighted image shows very high-signal-intensity mass. (C) Axial postgadolinium T1-weighted fat-saturated image shows contrast enhancement of the mass. There are internal septa with low signal intensity on all pulse sequences (MRI appearance of polkadot). (D) Sagittal postgadolinium T1-weighted fat-saturated image shows MRI appearance of corduroy pattern with multiple vertical hypointense septa.

The mass had low signal intensity on T1-weighted images (Fig. 2A) and very high signal intensity on T2-weighted images (Fig. 2B). T1-weighted images, there was homogeneous enhancement of the lesion (Fig. 2C). There were internal septa with low signal intensity on all pulse sequences (Fig. 2D).
47-year-old man with intracortical hemangioma. A whole-body bone scan image shows slightly increased uptake in the right distal tibia.

A whole-body bone scan showed an area of slightly increased uptake in the right tibia (Fig. 3).
47-year-old man with intracortical hemangioma. There is remodeled cortical and trabecular bone with increased numbers of vessels in Haversian systems and intertrabecular space. The vessels varied from small capillary-type vessels to more cavernous-appearing vascular spaces (HE stain, 100x).
