A Case of Multiple Cavernous Hemangiomas with Skin and Central Nervous System Involvement

Rare case of vascular malformations in both skin and brain: Case report and published work review

Solitary venous malformation (VM) of the skin, previously known as cavernous hemangioma, is frequently observed in the dermatological field, but multiple acquired VM are rare. We present a case of multiple VM of the skin associated with multiple cerebral cavernous malformations (CCM) in a 70-year-old Japanese woman. In addition, we summarize seven reported similar cases, including the present case. That some reports have described concomitant VM of the skin and CCM, together with the present case, suggests a tight relationship or a common pathogenetic pathway between these two diseases.

Review of familial cerebral cavernous malformations and report of seven additional families

Cerebral cavernous malformations are vascular anomalies of the central nervous system characterized by clusters of enlarged, leaky capillaries. They are caused by loss-of-function mutations in KRIT1, CCM2, or PDCD10. The proteins encoded by these genes are involved in four partially interconnected signaling pathways that control angiogenesis and endothelial permeability. Cerebral cavernous malformations can occur sporadically, or as a familial autosomal dominant disorder (FCCM) with incomplete clinical and neuroradiological penetrance and great inter-individual variability. Although the clinical course is unpredictable, symptoms typically present during adult life and include headaches, focal neurological deficits, seizures, and potentially fatal stroke. In addition to neural lesions, extraneural cavernous malformations have been described in familial disease in several tissues, in particular the skin. We here present seven novel FCCM families with neurologic and cutaneous lesions. We review histopathological and clinical features and provide an update on the pathophysiology of cerebral cavernous malformations and associated cutaneous vascular lesions. © 2016 Wiley Periodicals, Inc.

Cavernous Hemangioma of the Cavernous Sinus, Skin, and Retina: Hemodynamic Changes after Treatment: Case Report

OBJECTIVE

There are several reports concerning cavernous hemangiomas of the skin and central nervous system. Additional retinal involvement has also been reported.

CLINICAL PRESENTATION

The authors report a 69-year-old woman with a giant extra-axial cavernous hemangioma of the right cavernous sinus involving the supra- and parasellar region, retina, and skin.

INTERVENTION

Shrinkage of its cutaneous part lead to subsequent increase of the volume of the intracranial part. Owing to compression of the optic and the oculomotor nerves, oculomotor disturbances, ptosis, and visual impairment to 0.2 occurred. Via a pterional approach microsurgical removal of the tumor except for a remnant of the intracavernous part was performed.

CONCLUSION

Hemodynamic connection between cutaneous, retinal, and intracranial hemangiomas should be considered.

Ocular vascular hamartomas: the relationship with phakomatoses and possible commonalities in pathogenesis

BACKGROUND

Ocular vascular hamartomas may present as isolated lesions or as part of a multisystemic congenital syndrome known as vascular phakomatoses. These syndromes are characterized by ocular, cerebral, and cutaneous lesions. Although each of these lesions manifests distinct characteristics, there may be overlapping characteristics and manifestations attributable to a common pathogenesis.

METHODS

A case series and a literature review are presented illustrating ocular and systemic manifestations associated with vascular hamartomas, with each case representing varying degrees of ocular and systemic expression.

CONCLUSION

Because of the potential ocular morbidity and systemic mortality associated with vascular hamartomas and associated syndromes, the optometrist plays an important role in the management of these patients. In general, understanding the pathogenesis of these diseases may contribute to future treatment and prevention opportunities.

Recurring polysomatic hemangiomatosis: a new syndrome?

Systemic hemangiomatosis is extremely rare in adolescents and adults. The authors describe a 37-year-old man with a history of hepatic, splenic, cerebral, and multiple recurring osseous hemangiomas since age 14. After a 9-year period without disease progression, the patient presented with an acute bilateral lower extremity myelopathy. This was secondary to a T11 vertebral hemangioma that compressed the spinal cord. A 2-week course of radiation therapy failed to alleviate the patient's symptoms. Successful T11 vertebrectomy was then performed to decompress the spinal cord. The many organs and serially involved bones may represent a distinct variant of hemangiomatosis not previously described in the literature.
