Stereotactic radiosurgery (SR) is being used with increasing frequency in the treatment of brain metastases. This study provides data from a clinical experience with radiosurgery in the treatment of cases with multiple metastases and identifies parameters that may be useful in the proper selection and therapy of these patients. From January 1993 to April 1997, 97 patients (43 women and 54 men; median age 58 years) suffering from multiple brain metastases (median 3; range 2-4) in MRI scans, received SR with the Gamma Knife. The median dose at the tumor margin was 20 Gy (range 17-30 Gy). Median tumor volume was 3900 cmm (range 100-10,000). Different forms of hemiparesis, focal and generalized seizures, cognitive deficit,
headache
, dizziness and ataxia had been the predominant neurological symptoms. Major histologies included lung carcinoma (44%), breast cancer (21%),
renal cell carcinoma
(10%), colorectal cancer (8%), and melanoma (7%). The median survival time was 6 months after SR. The actual one-year survival rate was 26%. In univariate and multivariate analysis, a higher Karnofsky performance rating and absence of extracranial metastases had a significantly positive effect on survival. Local tumor control was achieved in 94% of the patients. Complications included the onset of peritumoral edema (n = 5) and necrosis (n = 1). SR induces a significant tumor remission accompanied by neurological improvement and, therefore, provides the opportunity for prolonged high quality survival. We conclude that radiosurgical treatment of multiple brain metastases leads to an equivalent rate of survival when compared to the historic experience of patients treated with whole brain radiotherapy. Patients presenting initially with a higher Karnofsky performance rating and without extracranial metastases had a median survival time of nine months. Each such case should therefore be evaluated based on these factors to determine an optimal treatment regimen.

A 76-year-old man with postoperative
renal cell carcinoma
accompanied by multiple lung metastasis was being treated with recombinant interferon-alpha. After administration of 3 MU/day on 3 days/week for 1 month, he complained of
headache
and tinnitus. During continuous treatment for 3 months, he complained of appetite loss, low-grade fever and dyspnea. He was then referred to our Department of Internal Medicine. Electrocardiography indicated a complete A-V block, and chest radiography (CXR) showed a reticular shadow in both lower lung fields and bilateral pleural effusion. Chest computed tomography (CT) indicated subpleural emphysematous changes, multiple nodules, consolidation shadow with ground glass opacity in both lower lobes, and bilateral pleural effusion. The findings in the bronchoalveolar lavage (BAL) fluid included increases in the numbers of lymphocytes and eosinophils. We reached a diagnosis of interferon-alpha-induced pneumonitis on the basis of the patient's clinical course, and the CXR, chest CT and BAL fluid findings. Treatment with methylprednisolone pulse therapy for 3 days and then administration of prednisolone for 1 month resulted in marked improvement in the complete A-V block and interstitial pneumonitis. At day 7 after discontinuation of prednisolone, the serum level of C-reactive protein increased, and CXR showed bilateral pleural effusion. We therefore believe that the pleural effusion was probably also induced by interferon-alpha. Interferon is an effective drug for chronic hepatitis C and malignant diseases. Many complications have been reported during interferon therapy. However, although these complications, such as interstitial pneumonitis, complete A-V block and pleural effusion, have rarely been reported, careful attention is required during interferon therapy in case any appear.

A rare case of von Hippel-Lindau (VHL) disease with bilateral pheochromocytomas, right
renal cell carcinoma
, right pelvic carcinoma, spinal hemangioblastoma and primary hyperparathyroidism is described. A 78-year-old woman had a history of hypertension from her forties. She suffered from
headache
and body weight loss. Abdominal CT revealed bilateral adrenal tumors and right external renal tumors enhanced in early stage. MIBG scintigraphy exhibited a high accumulation of tracer in both adrenal glands. On the basis of the radiographic findings and endocrinological results, the patient was diagnosed as having bilateral pheochromocytomas and right
renal cell carcinoma
. A bilateral adrenectomy was performed, followed by surgery for resection of the
renal cell carcinoma
. The other resected right kidney showed a clear cell subtype that was determined to be
renal cell carcinoma
, and proved that the pelvic tumor was transient cell carcinoma. Spinal MRI showed spinal hemangioblastoma. von Hippel-Lindau (VHL) gene mutation for the patient was found. We diagnosed the patient as VHL because of the existence of spinal hemangioma and a VHL disease gene. Parathyroid echo revealed a hypoechoic space on the back of the left lobe, and serum calcium and intact PTH to be elevated. The patient was diagnosed as primary hyperparathyroidism. We report the first case of a patient with VHL disease complicated with bilateral pheochromocytomas, right
renal cell carcinoma
, right renal pelvic carcinoma and primary hyperparathyroidism. The life expectancy of affected individuals has been less than 50 years. Since the prognosis may be improved by an early diagnosis, affected individuals with VHL complexes should undergo cranial, spinal MRI and abdomen CT. The families may benefit from presymptomatic detection of affected gene carriers and the exclusion of at-risk family members by negative test results.

Advanced
renal cell carcinoma
is a chemoresistant disease. Immunotherapy with alpha interferon or interleukin (IL)-2 has produced response rates of approximately 15%, but better treatments are needed. IL-4 is a cytokine produced by activated CD4+ lymphocytes and has pluripotent activities including inhibiting the in vitro proliferation of human
renal cell carcinoma
cell lines. In this trial, patients were required to have a histologic diagnosis of
renal cell adenocarcinoma
with measurable disease and performance status (SWOG) of 0-1. Patients had to have adequate bone marrow, renal, and hepatic function as well as no clinically significant pulmonary or cardiac dysfunction. IL-4 was given by subcutaneous injection at a dose of 5 micorg/kg/d, daily for 28 days followed by a 7-day rest period. Fifty-eight patients were registered with seven patients ineligible and two patients not analyzable because they did not receive treatment. In the 49 eligible and analyzable patients, there were no confirmed complete or partial responses. There was one unconfirmed partial response in retro-caval lymph nodes, but no verifying measurement was done. There were seven patients with stable disease, no response, 25 with increasing disease/progression, and 16 patients whose assessment was inadequate to determine response. The median time to progression was 3 months, and the median survival was 13 months. Toxicity was significant with the most common side effects nausea, vomiting, or diarrhea, followed by
headache
/pain and malaise/fatigue/lethargy. There were 13 instances of grade 4 toxicity that occurred in nine different patients. Unique toxicities included Bell's palsy in three patients and hypoglycemia in a previously well-controlled diabetic. Despite promising growth inhibitory and immunologic effects, IL-4 in this dose and schedule is not useful for the treatment of patients with disseminated
renal cell carcinoma
.

Symptomatic metastases to the pituitary (MP) from
renal cell carcinoma
(
RCC
) are rare. In this largest case series reported, we describe the clinical features, treatment and outcome of 5 patients. Over a 6-year period (2000-2006), we treated 5 patients (3 males; mean age 61 years) with large sellar masses and
RCC
. Four patients had a history of
RCC
, while in one,
RCC
was diagnosed after surgery.
RCC
was diagnosed a median of 11 years prior to diagnosis of MP (range 0-27 years). Four patients had previously developed distant metastases. Clinical presentation included bitemporal hemianopia (3 patients), lethargy (3),
headaches
(2) and diabetes insipidus (DI) (2). Panhypopituitarism was present in 3 patients and the other two had deficiency of at least ACTH and gonadotropin axes. Elevated prolactin was seen in 3 patients. MRI showed an enhancing sellar mass with suprasellar extension and chiasmal compression in all; prominent vascular flow voids were seen in 2. Three patients underwent transsphenoidal surgery and radiation, while 2 underwent radiotherapy alone. Four patients are alive (follow up 6-46 months); 1 patient died due to systemic metastases at 12 months. Metastases to the pituitary from
RCC
cause more severe hypopituitarism and visual dysfunction compared to those from other primaries, whereas DI is less common. MRI shows contrast enhancement, stalk involvement, sclerosis and/or erosion of sella and presence of vascular flow voids. Combined treatment using decompressive surgery and stereotactic radiotherapy may result in better outcomes.

Metastatic tumors involving the pituitary gland are an uncommon finding and occur in up to 1% of all pituitary tumor resections. A 74-year-old man had progressive vision deterioration, over the 30 days prior to consultation. He did not complain of
headache
or polyuria, but referred to intestinal constipation. Five years ago, he underwent a right radical nephrectomy for
renal cell carcinoma
, followed by chemotherapy and radiotherapy for lung and parotid metastases. On ophthalmologic examination, there was a left abducens nerve palsy and bitemporal hemianopia. Magnetic resonance imaging demonstrated a sellar mass with suprasellar cistern extension compressing the optic chiasm. Endocrinological evaluation revealed central adrenal and gonadal insufficiencies. The patient underwent a transsphenoidal tumor resection that revealed
renal cell carcinoma
. This case illustrates that metastatic pituitary lesions can mimic typical symptoms and signs of pituitary macroadenoma. Furthermore, clinical diabetes insipidus, a common finding of pituitary metastases, can be absent.

Renal cell carcinoma
(
RCC
) is an uncommon tumor that rarely metastasizes primarily to the brain. Brain metastases are commonly observed in patients with metastatic
RCC
, with a reported incidence of 2-17%. The prognosis of brain metastatic
RCC
is poor. In this carcinoma type, the source is commonly evident. We report a case of a patient with undiagnosed incidental
RCC
, who presented chronic
headache
as the first manifestation.

Cardiac metastases from
renal cell carcinoma
are rare but should be recognized when present. We report PET/CT findings in a patient with
headache
and diplopia and cerebral metastasis from an unknown primary of clear cell adenocarcinoma origin. PET/CT revealed uptake with a left
renal cell carcinoma
, and revealed multiple metastatic lesions, including an FDG-avid metastasis within the left ventricular myocardium.

A non-functioning paraganglioma is usually benign, however, it may cause distant metastases. There is no histological appearance for the diagnosis of malignancy or absolute criteria for predicting malignant potential. Bony metastases from paraganglioma are known to occur, but, skull metastases are very rare. We report a case of intracranial metastases from a renal paraganglioma. A 61-year-old male presented with temporal
headache
and exophthalmos on the left side. Seven years prior, he underwent surgery to remove a mass in the right renal hilum, which was diagnosed as
renal cell carcinoma
at that time. Computed tomography and magnetic resonance imaging showed a ring-like enhanced mass in the left middle fossa, which destroyed the sphenoid bone and the lateral wall of the orbit. Another osteolytic lesion was revealed in the occipital bone. The fragile tumor was totally resected. Histopathological study revealed the Zellballen pattern with extensive coagulation necrosis. No apparent nuclear atypia or mitosis were present. Immunohistochemistry showed reactivity for synaptophysin and chromogranin A in the tumor cells. Review of the surgical specimen of the previously resected renal tumor revealed the same pathological and immunohistochemical findings as those of chief cells in the middle fossa tumor. Thus, this tumor was diagnosed as a malignant paraganglioma metastasized from renal paraganglioma. After six cycle chemotherapy with cyclophosphamide and vincristine, his condition was stable for two years, however, he died four years after the diagnosis of malignancy.

We report a rare case of a
renal cell carcinoma
(
RCC
) metastasis occupying the cerebellopontine and cerebellomedullary cisterns, and describe an alternative strategy for embolizing hypervascular intracranial tumors. A middle aged patient with a distant history of
RCC
presented with
headaches
, nausea, and vomiting, and was found to have an enhancing mass in the left cerebellopontine and cerebellopontine cisterns. The initial surgical resection was aborted due to excessive bleeding. After an unsuccessful attempt at intra-arterial embolization, the patient returned to the operating room and the tumor was devascularized by direct needle puncture Onyx embolization under biplane fluoroscopy. The devascularized tumor was then successfully dissected from the brainstem and adherent lower cranial nerves. In properly selected cases, open surgical direct needle puncture embolization of intracranial vascular tumors under biplane fluoroscopy is a viable alternative devascularization method.
