Cystic Intracranial Hemangiopericytoma; Case report

Hemangiopericytomas is a rare malignant tumor of the central nervous system having an incidence of 1-3.8% of all primary intracranial meningeal tumors, and the occurrence of cystic hemangiopericytomas is even rarer. We report our recent experience of a case of cerebral hemangiopericytoma associated with a large cyst in a 38 year-old man. The patient presented with 1-month history of headache. Computerized tomography(CT) and magnetic resonance image(MRI) showed a huge-sized, cystic tumor in the left frontal region. Histopathological report of the excised tumor confirmed cystic hemangiopericytoma. Over the years, the issue of classifying hemangiopericytoma as a form of meningioma has been controversial. Since hemangiopericytoma differs from that of ordinary meningiomas because of its extremely malignant behavior and different histological and ultrastructural properties, the author suggest that hemangiopericytoma classified not with meningiomas. Regardless of classification, total surgical removal of this tumor is crucial due to its tendency for local recurrence despite aggressive resection.

Extradural Granulocytic Sarcoma of the Thoracic Spine

Granulocytic sarcoma(chloroma) is an uncommon and solid tumor composed of immature cells of the mycloid series usually seen during the course of myelogenous leukemia or myeloproliferative disorders. The common sites for the occurrence of granulocytic sarcoma are soft tissue, periosteum, bone, lymphoid tissue, skin, gastrointestinal tract and testis. But extradural presentation of the spine is very rare. We report two cases of extradural granulocytic sarcoma of the spine. Early recognition of the etiology of the paraplegia and the underlying systemic involvement with leukemia resulted in an excellent neurological and hematological outcome.

Clinical Analysis of Multiple Intracranial Aneurysms

Author reviewed the 31 cases of multiple intracranial aneurysms clinically from January 1981 to July 1987, at Inje College Busan Paik Hospital. The results obtained were as follows: 1) The incidence of multiple intracranial aneurysm was 7.8%. In most cases(94%), the number of aneurysm was two. 2) Approximately over 70% of patients were 6th and 7th decades, male to female ratio was 1:3.4. 3) The location of multiple intracranial aneurysms was in order, on the opposite side(39%), on the same side(26%), one in the midline and one on the side(29%). The location of indivisual aneurysms was in order, P-com. A(36%), MCA(25%), A-com. A(17%), ICA(13%). 4) The site of the ruptured aneurysm was determined by CT finding(55%), focal mass effect and spasm in angiography(29%), and others. The accurary was 97%. The possibility of rupture at each location was A-com. A(73%), P-com. A(57%), ICA(38%), MCA(31%). 5) 12 cases among them were treated with one-stage operation and 9 cases with two-stage operation. The post-operative favorable outcome was estimated in 13 cases(54%), the surgical mortality was 13%. There was no statistical difference between two groups.
