Abstract

Intraosseous cavernous hemangioma is a rare cause of osteolytic lesions of the skull, and its multifocal type is even more infrequent. This tumor is difficult to accurately diagnose by imaging and can be confused with osteolytic Langerhan’s cell histiocytosis or other neoplasms. Here we present a case of multifocal intraosseous cavernous hemangioma of the skull treated with surgical intervention in our hospital five years ago. A review of related literatures and case reports is also provided to help clarify the diagnosis and devise treatment regimens. In light of the difficulties of early diagnosis, early en bloc surgical removal is recommended.

Highlights

Primary cavernous hemangiomas are rare skeletal tumors accounting for 0.7-1% of all bone neoplasms [4]
Cavernous hemangiomas are usually unifocal, and they represent 0.2% of all benign neoplasms of the skull

Summary

Introduction

Primary cavernous hemangiomas are rare skeletal tumors accounting for 0.7-1% of all bone neoplasms [4]. These tumors, which arise from the intrinsic vasculature are mostly found in vertebral bodies. Cavernous hemangiomas are usually unifocal, and they represent 0.2% of all benign neoplasms of the skull. The majority of these lesions are asymptomatic, but patients can. C present with focal pain or palpable mass. A multifocal osteolytic lesion can initially be confused with Langerhan’s cell histiocytosis (LCH) or a malignant neoplasm. We present a case of multifocal cavernous hemangiomas of the skull bone
