BACKGROUND The authors report the case of a 53-year-old woman suffering from thoracic myelopathy caused by intraspinal dissemination of hemangiopericytoma. In literature, hemangiopericytoma is commonly found as an intracranial lesion, and often hematogenously metastasizes to the bone or liver; however, intradural spinal dissemination is extremely rare. CASE DESCRIPTION The patient presented w...

Hemangiopericytoma is a rare vascular neoplasm, which arises from specialized cells (pericytes) around the walls of blood vessel. About 50% of hemangiopericytoma in the series of Stout occurred in the oral cavity and pharynx. Under the World Health Organization (WHO) classification, hemangiopericytoma and solitary tumors of the soft tissues are regarded as features of the same entity in the sof...

Lipomatous hemangiopericytoma is a rare variant of hemangiopericytoma. Only a few cases of LHPC have been reported to date, with only two cases of this entity having been reported in the head and neck area, and none intracranially. We present the clinical, radiological, and histological features of the first reported case of a sellar lipomatous hemangiopericytoma, and review the literature. Mat...

BACKGROUND Hemangiopericytoma is a soft tissue vascular neoplasm arising from capillary pericytes and is found throughout the body in soft tissues and bone. It was first described in 1942. Primary vascular neoplasm of the spleen constitutes the majority of nonhaematolymphoid splenic tumors like haemangioma, lymphangioma, hemangioendothelioma, hemangiopericytoma etc. Splenic hemangiopericytoma i...

Spinal intradural hemangiopericytoma is a very rare tumor and can be characterized by massive bleeding during surgeries, frequent recurrence, and metastasis. However, definite radiologic differential points of hemangiopericytoma are not known. We describe an unexpected hemangiopericytoma case with large bleeding and management of the tumor. A 21-year-old man visited complaining of progressive n...

Hemangiopericytoma is a hypervascular soft tissue sarcoma with a predilection for the extremities. It has two clinical types according to the age of presentation: Infantile hemangiopericytoma ( < 1 years) and adult type hemangiopericytoma ( > 1 years). The intracranial location is very rare and accounts for only 0.4-1% of all primary brain tumors, with only 10% detected in the pediatric age gro...

We describe a case of a 53 years old patient who underwent right nephrectomy for a renal tumor in 2005. The histological examination revealed an hemangiopericytoma with graveness signs. Ten years later, the patient developed a huge abdominal mass. CT scan showed a voluminous locally advanced tumor measuring 30*20 cm. The mass was multilobed and hypervascularized (A) Witch was compatible with a ...

OBJECTIVE To describe the case of a patient with paratesticular hemangiopericytoma and to perform a bibliographic review. METHODS We describe the case of a patient with paratesticular hemangiopericytoma. We conducted an exhaustive literature review in different databases to support the case discussion. RESULTS We present the case of a 64 year old male with a progressively growing mass in th...

A case of hemangiopericytoma in the cervicothoracic spine is reported. A 43-year-old man was admitted to our hospital with pain in the scapular region radiating to the left upper extremity, numbness, and weakness of the legs. Magnetic resonance image revealed an intraspinal, extradural mass at the level of the C6-T2 vertebral bodies. The lesion also involved the dorsal paraspinal area with a gi...

The Hemangiopericytoma is a rare vascular tumour originating from the pericytes, which are found on external surface of capillaries and thought to act as sphincter that controls blood flow. It has high propensity for recurrence metastasis.The tumor usually develops slowly enlarging painless mass.It typically occurs in soft tissues extremities trunk, rarely seen oral cavity.15–16% head neck...
