Bilateral traumatic hemorrhage of the basal ganglia

Hemorrhage of the basal ganglia is common in hypertensive patients, and most of the cases are spontaneous unilateral hemorrhage. Traumatic basal ganglia hemorrhage is uncommon, while bilateral hemorrhage of the basal ganglia after trauma is an extremely rare entity. This report described a rare case of bilateral hemorrhage of the basal ganglia after head trauma. We also analyzed the mechanisms and reviewed relative literatures.     

Traumatic hemorrhage in the basal ganglia in the child. Five cases

Traumatic hemorrhages in the basal ganglia were seen in five children. The CT findings and the characteristics of these injuries were discussed. All of children were injured in car accidents. They ranged in age from 3 to 13 years. The patients comprised 3 boys and 2 girls. On admission, case 1 was conscious and case 2 was in a stupor. Case 1 and 2 were mild cases in which spotty hematomas were seen in the ganglionic region. They recovered fully. Case 3-5 were severe cases in which massive hematomas were seen in the ganglionic region. On admission, their consciousness ranged from stupor to coma. We performed operations on two of them but their recoveries were unsatisfactory. Their results were as follows. One had residual hemiparesis and dysarthria, one experienced tetraparesis and dysarthria and the last went from coma to a vegetative state. Concerning the directions of the impacts, 4 were hit in the frontal region or face and the last one received blows on the occipital region. Skull fractures were seen in two cases. Mandibula and clavicula fractures were seen in the other two cases. Only one child had no fractures. We conclude that pediatric traumatic hemorrhages in the basal ganglia are induced by severe impact on the frontal or occipital regions. The size of hematomas in this injury is spotty or massive. The massive type has a poor prognosis. On the other hand, the spotty type's prognosis is good. We speculate that impact to the head causes a shear strain in the ganglionic region. At that time, vessels in the area are injured.     

Prognosis in traumatic basal ganglia haematoma

Summary Twenty two patients with traumatic basal ganglia haematoma were studied. The mean Glasgow Coma Score on admission was 7. 17 patients had sustained high acceleration/deceleration injuries. The location and size of haematoma did not correlate with prognosis. Outcome was poor in 7 patients, while 8 patients died.     

Bilateral asymmetric traumatic hip dislocation in adolescence: a report of two cases and review of the literature

Traumatic bilateral asymmetric hip dislocation is an extremely uncommon injury and rarely seen in children. We report two such cases in adolescent females injured in separate accidents. One of these patients also suffered a left femoral shaft fracture, ipsilateral labral avulsion and contra-lateral acetabular fracture. We report our experience in the management of this complex injury pattern and review the pertinent literature on the subject.     

Three cases of cryptic arteriovenous malformation in basal ganglia manifested by putaminal hemorrhage

Three cases of histologically proven cryptic arteriovenous (AV) malformation of the basal ganglia are reported. Seventeen cases of patients showing putaminal hemorrhage in the CT scan underwent craniotomy for evacuation of a hematoma between January 1986 and December 1988. The preoperative diagnosis was hypertensive putaminal hemorrhage. In all three cases a network of abnormal vessels around the internal capsule was detected at surgery. Case 1: A 62-year-old male was admitted to our hospital with consciousness disturbance (JCS 20), total aphasia and right hemiparesis. The CT scan showed left putaminal hemorrhage. The volume of the hematoma was 45 ml by CT criteria. Left carotid angiography did not demonstrate any abnormal findings. Case 2: 69-year-old male was admitted with consciousness disturbance (JCS 10) and right hemiparesis. Left putaminal hemorrhage (volume 25 ml) was recognized on the CT scan. Two hours after admission, the consciousness level suddenly deteriorated (JCS 100). At that moment, the volume of the putaminal hematoma had increased to 100 ml. AV malformation was not detected by left carotid angiography. Case 3: A 50-year-old male was admitted with consciousness disturbance (JCS 20), total aphasia and right hemiparesis. The CT scan showed left putaminal hemorrhage of 73 ml. Pathohistological examination proved AV malformation in each case. The three cases described here suggest the following; 1) The incidence of the basal ganglia cryptic AV malformation has been considered low, but meticulous examination shows that among the cases diagnosed as hypertensive hemorrhage, AV malformation is not infrequently the hidden cause.(ABSTRACT TRUNCATED AT 250 WORDS)     

Bilateral renal cell carcinoma: report of two cases

Two cases of bilateral renal cell carcinoma are reported. The first case is of a 54-year-old male who visited our hospital on March 7, 1984 complaining of colicky pain in his left flank. Intravenous urography showed a large mass in the upper pole of the left kidney causing deformity and dislocation of the upper calyces. There were no remarkable findings in the right kidney. Abdominal CT-scan and arteriography revealed a round and hypervascular tumor with soft tissue mass density in the upper pole of both kidneys. Nephrectomy of the left and segmental resection of the upper pole of the right kidney were performed on April 11, 1984. The second case is a 47-year-old male who visited our hospital complaining of total gross hematuria. Intravenous urography showed a large soft tissue mass at the lower pole of the left kidney. Abdominal CT-scan revealed a large tumor mass associated with central necrosis in the left kidney and also a small tumor lesion at the center of the contralateral kidney. Bilateral nephrectomy was performed on December 19, 1984, and the patient was referred to hemodialysis treatment. The cut section of the nephrectomized right kidney specimen revealed multiple minor accessory tumors. Both patients have been doing well without any evidence of recurrence or metastasis.     

Endoscopic treatment of traumatic basal encephaloceles: a report of 8 cases

OBJECT: Basal encephaloceles are rare entities that can present as congenital diseases; however, traumatic lesions due to head injuries or iatrogenic causes have been described in the literature. In this study the authors aimed to define placement techniques for free grafts in repairing traumatic basal encephaloceles and to describe the long-term effectiveness of endoscopic treatment. METHODS: Between September 1997 and December 2006, 8 patients with traumatic encephaloceles underwent endoscopic surgery. A free graft following an underlay (2 cribriform plate and 4 ethmoid fovea defects) or obliteration (2 sphenoid defects) procedure was used as the repair material. RESULTS: All traumatic basal encephaloceles with the associated skull base defects and cerebrospinal fluid (CSF) leakage were successfully treated via the endoscopic approach. There were no major complications or recurrence of meningitis or leakage of CSF encountered after an average follow-up of 77 months. CONCLUSIONS: Long-term follow-up results demonstrated that endoscopic surgery was suitable for the treatment of traumatic basal encephaloceles. The underlay procedure is more appropriate than the overlay procedure in repairing large defects of the anterior skull base. Meticulous manipulations of the endoscope following precise autograft placement are mandatory for the successful repair of traumatic basal encephaloceles.     

Bilateral occipital condyle fracture: report of two cases.

Occipital condyle fractures are a rare finding in trauma victims. Bilateral fractures are even more unusual and have typically been reported in autopsy studies. We treated two patients with bilateral occipital condyle fractures who had only minor symptoms. Anderson and Montesano's classification,(1) possible cranial nerve palsies, diagnosis, and treatment of this rare fracture are discussed.     

Parkinsonian syndrome caused by traumatic hematomas in the basal ganglia

A 61 year old man, without neurological history, has a coma after a facial concussion. While the consciousness is improving, parkinsonism feature is observed with tremor at rest, rigidity and bradykinesia. From the radiological point of view, hematoma of right and left basal ganglia is observed on C.T. Scan performed 6 hours after cranial trauma. The authors study the role of these 2 hematomas in genesis of parkinsonism through literature data and they bring a mean piece in pathophysiology of parkinsonism reported in boxers.     

Bilateral germ cell tumors involving the basal ganglia and thalamus

Two cases of a human chorionic gonadotropin-producing germ cell tumor originating bilaterally in the basal ganglia and thalamus are reported. The biological behavior and clinical characteristics were similar to those of unilateral germinomas involving the basal ganglia and thalamus. Common clinical features were slowly progressive unilateral pyramidal signs and bilateral and/or unilateral extrapyramidal signs which occurred either concomitantly or sequentially. Bilateral symmetrical lesions were demonstrated by computed tomography and/or magnetic resonance imaging at an early stage of illness. Serum and cerebrospinal fluid human chorionic gonadotropin levels were elevated (116 and 141 mIU/ml, respectively) but decreased and remained within normal limits after radiation therapy alone. Radiosensitivity was confirmed by repeated computed tomographic scans and tumor marker measurements. Multiple concomitant germ cell tumors is a rare, but interesting lesion, especially considering its pathogenesis and oncogenesis.     

Bilateral traumatic scapholunate dissociation: Case report

In 1923, Destot described scapholunate dissociation (SLD) which results from disruption of the scapholunate interosseous ligament. Several hypotheses have been proposed to explain SLD, such as traumatic, congenital, ligamentous laxity, and synovial pathology. We are presenting a very rare and challenging case of elderly patient who had traumatic bilateral scapholunate dissociation after a fall, which was managed by ligament reconstruction using bone anchor suture, and kirschner wire fixation. The identification of risk factors for frequent falls among older persons is of paramount importance to prevent further serious injuries.     

Barbiturate therapy in traumatic cerebral vascular disease: report of two cases

We report two cases of traumatic cerebral vascular disease which were treated successfully with barbiturate. The first case sustained blunt trauma to the bilateral vertebral arteries, resulting in complete occlusion of both arteries. After ligation of the injured vertebral arteries, multiple cerebral infarction appeared. Cerebral angiography revealed dissection and stenosis of the bilateral internal carotid arteries. We treated this case with barbiturate (Thiamylal) in combination with administration of heparin. The second case sustained cerebral contusion and traumatic subarachnoidal hemorrhage as a result of a motor cycle accident. This patient deteriorated and cerebral angiography showed diffuse cerebral arterial vasospasms. When this was treated with induced hypertension, he developed recurrent subarachnoid hemorrhage. In order to protect the brain from ischemia without elevating blood pressure, we employed barbiturate therapy and the patient recovered without major neurological deficit. The condition of severe head injury with cerebral ischemia is complicated. Therefore it has been hard for neurosurgeons to cure the patient with this condition. But we treated it with barbiturate successfully. Barbiturate therapy in severe head injury with cerebral ischemia may decrease the mortality in that group of patients considered difficult to treat with the usual therapeutic modalities.     

Bilateral metachronous germinoma of the basal ganglia occurring long after total removal of a mature pineal teratoma: case report

OBJECTIVE AND IMPORTANCE: We report the extremely rare occurrence of a second germ cell tumor at a different site and with different histological types long after total removal of a mature pineal teratoma. CLINICAL PRESENTATION: A 10-year-old boy who presented with headache and vomiting was admitted to our hospital. Neuroradiological studies revealed a tumor in the pineal region. The tumor was totally removed. Histologically, the tumor proved to be a mature teratoma. The patient's postoperative course was uneventful. The patient received no adjuvant therapy and was followed in the outpatient clinic. Three years later, he was readmitted with transient left upper limb weakness and vomiting. Neuroradiological studies showed a tumor in the bilateral basal ganglia. INTERVENTION: The second tumor, which was located in the right basal ganglion, was partially removed for biopsy. Histologically, the tumor proved to be a germinoma. The patient received three cycles of combination chemotherapy consisting of carboplatin and etoposide with radiotherapy. After the second course of chemotherapy, magnetic resonance imaging studies revealed no evidence of the tumor. CONCLUSION: The second tumor was considered to be a de novo metachronous neoplasm rather than a recurrence of the original mature teratoma. We think that if primordial germ cell groups exist along the midline of the brain, more than two primordial germ cell groups could give rise to metachronous neoplasms at different sites and with different histological types.

Bilateral total hip arthroplasty in Morquio-Brailsford's syndrome: a report of two cases

We report two cases of bilateral cementless total hip arthroplasty in two young women affected by Morquio-Brailsford syndrome. Morquio-Brailsford disease belongs to the mucopolysaccharidoses; it shows growth retardation with disproportional dwarfism. Usually patients are affected by a severe joint degeneration from their 2nd or 3rd decade. Young age, severe dysplasia, and joint size are the main technical problems for a total hip replacement. Accurate radiographic and CT planning allows the use of standard prostheses instead of custom-made ones.
