Capillary Venous Malformation With Secondary Aneurysmal Bone Cyst of Temporal Bone

Federica Canzano et al. J Int Adv Otol. 2021 Sep.

Abstract

Aneurysmal bone cysts (ABCs) arising from vascular malformation are extremely rare, and none have been reported in the literature in English till now. We report a very rare case of secondary ABC of left temporal bone in a 5-year-old Caucasian boy who presented with a left sudden facial palsy associated with a painless non-tender mass of the left temporo-parietal region. The computed tomography (CT) and magnetic resonance imaging (MRI) features were suggestive of ABC secondary to a capillary venous malformation, with concurrent involvement of the squamous, mastoid, and petrous portions of the temporal bone. Surgical resection was performed. On follow-up, the patient was found to be doing well.

Figure 1.
(A) Pre-operative MR images (axial T2 sequence): multiloculated osseous lesion with multiple fluid-fluid levels. (B) Pre-operative MR images (coronal post-contrast-enhancement T1WI sequence): a thin rim of low signal intensity surrounded the lesion with non-homogeneous contrast enhancement.
Figure 2.
Figure 2.
(A) Pre-operative CT (coronal) with erosion of the inner and outer table of the skull, a complete erosion of the left tegmen tympani, and a partial erosion of bony external auditory canal. (B) Pre-embolization digital subtraction angiography: global left external injection shows the mass, which is mainly fed by the middle meningeal artery, ascending pharyngeal artery, and superficial temporal artery; it also shows areas with intensive blush and others with no signal at all.

Histopathology: original magnification (A) 2×; (B) 4×; (C) 10× and (D) 20×. Staining (A-D) hematoxylin–eosin. (A) The bone (arrow) is largely replaced by a small-vessel benign proliferation (arrowhead). In addition, large cavernous non-specific vessels (asterisk) can be detected in some areas. (B) The small-vessel proliferation (arrow) forms significant areas replacing, and focally infiltrating, the bone, which shows reactive changes. (C) There are sparse and dilated venous channels (arrow) with signs of iatrogenic pre-operative embolization (asterisk). (D) The small-vessel benign proliferation consists of thin dilated channels (arrow) with foci of osteoid matrix (arrowhead).

Post-operative MRI control shows complete excision of the mass (C coronal T2WI) re-expansion of the temporal lobe.
