Abstract
In this report, we describe a very rare case of metastatic epithelioid hemangio-endothelioma (EHE) originating from other organs such as the lung and requiring craniotomy due to subsequent hemorrhage. A 50-year-old man was diagnosed with EHE in the bilateral lungs, the mediastinum, and the right adrenal gland 8 years earlier. One year earlier, he had developed spinal metastasis. Six months earlier, a screening brain MRI had revealed multiple brain metastases of tumor. He developed subcortical hemorrhage from the tumor in the right parietal lobe and successfully underwent removal of hematoma and tumor. Histopathological examinations revealed EHE. Metastatic EHE is very rare but may be at high risk of intracranial hemorrhage. It is quite important to consider the possibility of brain metastasis and subsequent bleeding when treating patients with EHE.

Abstract
Background Composite hemangioendothelioma (CHE) is a rare, locally aggressive neoplasm of intermediate malignant potential. It is composed of a mixture of vascular tumors with a predilection for the dermis and subcutis of the extremities. Case Description In this report, we describe a 41-year-old man who presented with a 2-month history of headache, dizziness, and intermittent seizures. Magnetic resonance imaging showed a hemorrhagic, multilobulated, and dural-based mass with extension into the calvarium. The mass measured 10.3 × 4.8 × 4 cm along the interhemispheric fissure and encased the superior sagittal sinus. Excision was performed, and histopathologic examination revealed a heterogeneous mixture of vascular components consisting of epithelioid hemangioendothelioma, retiform hemangioendothelioma, and hemangioma. This is the first report of a primary intracranial CHE. Conclusion The spectrum of mesenchymal neoplasms within the cranium expands to encompass CHE.

Abstract
Hemangioendotheliomas are highly vascularized lesions, and their intracranial presentation is extremely rare. We present the case of a 65-year-old female patient who was evaluated for cranial deformity, headache, and left hemiplegia. Two bone lesions that were destroying and expanding the bone diploe with intracranial extension were identified in the fronto-temporal and parietal regions. Both lesions were multilobed and showed heterogeneous behavior. Mixed hemangioendotheliomas were identified after the successful resection of both tumors in two separate surgical procedures. The prognosis of this type of tumor with an intracranial location is not well-defined because there are too few reported cases.

Abstract
BACKGROUND Hemangiopericytoma and solitary fibrous tumor (HPC/SFT) are considered to be one category according to the WHO 2016 classification of central nervous system tumors. HPC/SFT are subdivided into infantile (congenital) and adult type. Both are extremely rare entities, with little knowledge about etiology, prognosis, and optimal therapeutic strategy. CASE DESCRIPTION A 10-day-old girl was referred to our neurosurgical department due to hypotonia, palsy of the right oculomotor nerve, and prominent frontal fontanel. Imaging studies revealed a large occupying mass in the right middle cerebral fossa and the suprasellar cisterns. Only a subtotal resection of the tumor was possible, and postoperatively, she underwent chemotherapy (CHx). After a 3-year follow-up, the girl has minimum neurologic signs and receives no medications, and she can walk when she is supported. CONCLUSION Congenital HPC/SFT is considered to have a benign behavior with a good prognosis. Treatment with gross total resection, when it is feasible, is the key to a good prognosis and low rates of recurrence. However, there is no consensus on the therapeutic strategy of a HPC/SFT, which is difficult to be completely resected. Literature lacks a therapeutic algorithm for these tumors, and thus, more clinical studies are needed to reach a consensus.

Abstract
BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare sarcoma of vascular origin, which is clinically and histologically intermediate between benign hemangioma and angiosarcoma. It is most commonly found in the liver, lung, and bone, however, 46 intracranial cases have been reported in the literature, of which this is the fifth reported suprasellar tumor. CASE DESCRIPTION A 45-year-old woman developed progressive lethargy, somnolence, and memory decline over the course of 6 months. On computed tomography (CT), she was found to have a large hypothalamic mass and underwent subtotal resection via a bifrontal craniotomy. CONCLUSIONS While primary intracranial EHE is an uncommon presentation of a rare tumor, the suprasellar region does not seem to be an unusual location when it does occur. Prognosis is generally good, and may be better for primary intracranial disease than that for EHE originating elsewhere. Surgery is the first line of therapy, with variable benefit from adjuvant chemotherapy or radiation when total resection is not possible. Chemotherapeutic approaches in current use are directed at preventing endothelial proliferation.

Abstract
The current study aimed to present the neuroradiological and histopathological features of intracranial hemangioendothelioma (HE). The computed tomography (CT; n=3) and magnetic resonance imaging (MRI; n=7) features, and the clinical presentations of 7 patients with pathologically documented HEs were retrospectively analyzed. Lesions were observed in the right side of the skull (the frontal bone in 1 patient and the parietal bone in 1 patient), the tentorium (2 patients), the cerebral falx (1 patient), the right cavernous sinus (1 patient) and the right temporal lobe (1 patient). The tumor was lobulated in 5 cases and round in 2 cases. The majority of tumors appeared isointense or hypointense with multiple scattered hyperintensities on T1-weighted MRI. Moreover, the lesions appeared as inhomogeneous hyperintense regions with multiple enlarged and tortuous blood flow voids on T2-weighted MRI. The lesions also showed marked gadolinium enhancement in a honeycomb pattern. CT scan results showed a isoattenuation region (32-47 HU), with numerous small, round, high-density foci. The 2 cases with skull lesions presented with local bone destruction and discontinuous bone lines of the tabula interna ossis cranii. In 1 case, MR angiography revealed abnormal vessels in the basilar region. A total of 4 cases were epithelial HE, 2 were retiform HE and 1 was kaposiform HE. Histological examination revealed endothelial cell proliferation with vascular lesions and a mucous matrix or dense fibrous mesenchyme. In conclusion, intracranial HE is rare, but should be considered in the differential diagnosis when evaluating intracranial neoplasms. A well-defined lobulated mass and imaging features that include internal heterogeneity, small scattered hemorrhages and thromboses, signal voids of vessels, and marked and delayed enhancement may confirm the diagnosis of HE.

Abstract
BACKGROUND Epithelioid hemangioendotheliomas (EHE) is an extremely rare tumor that can arise not only intracranially but also systemically. Its radiological characteristics and the mechanism underlying the multiple organ involvement in EHE are poorly understood. CASE DESCRIPTION A 24-year-old woman with a 7-month history of coughing and blood-stained sputum complained of visual disturbance in the right eye that had persisted for 1-month. Magnetic resonance (MR) imaging revealed multiple intraparenchymal masses with low-intensity on MR susceptibility-weighted images with minimal enhancement with gadolinium. Systemic computed tomography revealed multiple nodules in both lungs and the liver. Because her neurological status rapidly deteriorated, brain biopsy of the right frontal mass was performed. The pathological diagnosis was EHE. Over the following 3 months, the patient gradually developed disturbance of consciousness. She died at 4 months after admission because of significant intracranial hypertension. CONCLUSION Although intracranial EHEs are extremely rare, they should be included in the differential diagnoses of multiple small-sized masses with low-intensity on MR susceptibility-weighted images. We also emphasize that the systemic involvement of this tumor was more compatible with multicentric development than metastasis.

Abstract
Epithelioid hemangioendothelioma is an extremely rare intracranial tumor and is regarded as a low-proliferation tumor. We present two cases of primary intracranial epithelioid hemangioendothelioma and give an overview of the English literature pertaining to this disease. We described two new cases of primary intracranial epithelioid hemangioendothelioma and performed a search of MEDLINE (PubMed) using the words "epithelioid hemangioendothelioma". Only cases in the English language that were intracranially located and contained clinical information pertinent to the analysis were included. The tumor in case 1 originated from the right temporal bone and invaded the surrounding cranium, dura and temple muscles. The tumor in case 2 was located in the petroclival bone and had also invaded the surrounding cranium. Both tumors were well vascularized. The tumors were totally (case 1) or subtotally (case 2) removed with moderate blood loss. A total of 36 cases of intracranial epithelioid hemangioendothelioma were found in the literature. The tumor was typically diagnosed in young adults and infants. There was no sex predominance in adult patients, while in children, males were more frequently affected (M/F ratio, 3.5:1). Surgical removal was the main therapeutic protocol, and adjuvant therapy included radiotherapy or chemotherapy. Including the 2 patients presented here, a total of 38 patients were analyzed: 32 % showed local invasion, 24 % suffered a recurrence, 15 % had metastases, and the mortality rate was 15 %. Intracranial epithelioid hemangioendothelioma is a rare, low-proliferation tumor, but it exhibits some clinically malignant behaviors, such as local invasion, recurrence and metastasis. Total resection is mandatory where possible, and radiotherapy and/or chemotherapy are otherwise required. Preoperative feeding-artery embolization is recommended.

Abstract
Intracranial epithelioid hemangioendothelioma (EH) is a very rare vascular neoplasm. We describe a case of meningeal intracranial tumor in a 58 year old man, located in the greater wing of the sphenoid bone. The tumor was completely excised via pterional approach and the pahological analysis showed a hemorrhagic lesion with capillary-sized vessels lined by atypical-appearing endothelial cells that expressed CD31, CD34 and Factor VIII antigens. A diagnosis of EH was established, and one year after surgery the patient is symptom-free, without tumor recurrence or residual tumor. A review of the literature disclosed other 34 cases of intracranial EH. In these tumors, total resection is mandatory if possible, otherwise radiotherapy is recommended. Outcome is favorable in the majority of cases.

Abstract
Epithelioid hemangioendothelioma is a rare, well-differentiated endothelial tumor with a wide spectrum of clinical behavior and for which genetic data are extremely limited. We present a case of an epithelioid hemangioendothelioma in a 22-year-old male, which was analyzed with multiple cytogenetic approaches. Conventional cytogenetic analysis detected structural abnormalities of 11q13 and 11q14, rings, and marker chromosomes. Multi-color FISH (mFISH) and high-resolution multi-color banding (mBAND) analyses demonstrated that the aberrations of chromosome 11 were deletions and that the ring and marker chromosomes consisted of 12(q14 approximately q21) material. Comparative genomic hybridization (CGH) analysis revealed gains of 11(q13 approximately q14) and 12(q11 approximately q21), loss of 11(q21 approximately qter), and 2 amplicons at 12(q12 approximately q13) and 12(q14 approximately q21). Our data indicate that a subset of epithelioid hemangioendotheliomas may be characterized by complex rearrangements involving deletions and gains of 11q and 12q amplifications. The present case also shows that, in order to describe and understand such complex chromosome aberrations, chromosome analysis must be complemented with several molecular cytogenetic techniques.

Abstract
Congenital primary intracranial hemangiopericytomas are exceptionally rare tumors. We present a case of a fetus, with the prenatal sonogram at 33 weeks of gestation revealing a large cerebral tumor. Because of the enlarged head, a cesarean section was performed. The tumor was confirmed by postnatal ultrasound, magnetic resonance imaging (MRI) and biopsy. Elevated intracranial pressure and hemorrhage led to death on the 11th day. Autopsy revealed a 10x9 cm large inhomogeneous tumor located centrally, mainly in the posterior fossa. Histology showed a hypercellular and hypervascular tumor with extended necrosis and high mitotic rate. The tumor cells were positive for vimentin and CD34 antigens and negative for several neurological markers, desmin and CD31. The diagnosis of a congenital primary cerebral hemangiopericytoma was confirmed.

Abstract
Intra-axial involvement of the brain by an epithelioid hemangioendothelioma is rare, and biological properties of the tumor are uncertain. Most of the primary brain manifestations are confined to the cerebral hemispheres. We report magnetic resonance imaging and microscopic findings of a case of suprasellar involvement by an epithelioid hemangioendothelioma. The tumor was treated with a subtotal resection only, and no progression of the disease was noted during a 6-month follow-up. Review of the literature suggested that most epithelioid hemangioendotheliomas in the brain are unifocal tumors with a rather favorable clinical outcome.
