BACKGROUND Cavernous malformations (CMs) in the cerebellopontine angle (CPA) are rare, and most of such CMs reported to date are solid and extend from the internal auditory canal into the CPA. In contrast, cystic CMs that arise in the CPA and do not involve the internal auditory canal and dura of the skull base are extremely rare. CASE PRESENTATION A 50-year-old man presented with vertigo and...

Retroperitoneal hemangiomas are very rare. This paper presents the case of a 71-year-old female patient with giant cavernous hemangioma of the retroperitoneum who underwent surgical treatment for abdominal pain and left lower limb edema. Interventional staged treatment with percutaneous transcatheter arterial embolization prior to surgery was considered. Radical resection of the tumor was perfo...

Cavernous hemangioma of the optic chiasm is extremely rare, representing 1% or less of all cavernous hemangioma.1 Klein et al described the earliest reported lesion in 1979.2 Patients typically present with chiasmal apoplexy, characterized by sudden visual disturbance, headache, retro-orbital pain, and nausea.3 Acute dysfunction of the chiasm and/or optic nerve has been called chiasmatic apople...

Background: Primary intraosseous cavernous hemangioma is a rare bony tumor. To date, only 9 cases of multiple lesions and 2 cases with a dural tail sign have been reported. Case presentation: Here, we present a case of multiple cavernous hemangiomas of the skull with dural tail sign in a 24-year-old man. No abnormalities were observed in the right orbit by craniography, but frontotemporal bone ...

A case of an hemorrhagic cavernous hemangioma of the optic chiasma and the adjacent optic nerve in a 23-year-old woman is reported. The visual disturbance has subacute onset following a sudden lateralized headache. Through a fronto-pterional approach, an intrachiasmal hematoma was evacuated. A small cavernous hemangioma was found in the hematoma cavity, and it was totally removed. Visual sympto...

INTRODUCTION Liver cavernous hemangioma is the most common noncystic hepatic lesion, and a hemangioma that undergoes degeneration and fibrous replacement is called a hepatic sclerosed hemangioma. CASE PRESENTATION A 63-year-old Japanese man was admitted for detailed investigation of a liver tumor. Tumor markers carcinoembryonic antigen, alpha-fetoprotein, and CA19-9 levels in the peripheral b...
