A 71-year-old woman developed chronic progressive visual loss in the right eye and computed tomographic scan showed enlargement of the intraorbital optic nerve consistent with optic nerve sheath meningioma. Over 12 years, the contralateral optic nerve was not clinically affected, and serial neuroradiologic imaging showed no evidence of intracranial tumor extension. Death occurred from metastatic adenocarcinoma of the lung 14 years after initial visual loss. Examination of the postmortem specimen of optic nerve and chiasm revealed extradural extension of meningioma with spread to the region of the optic chiasm and hypothalamus. A large focus of metastatic adenocarcinoma was present within the intraorbital portion of the meningioma. Carcinoma metastatic to intracranial meningioma is rare; to our knowledge, this is the first reported case in an optic nerve sheath meningioma. Neuroimaging may be inadequate to predict the value of tumor excision in preventing intracranial spread of optic nerve sheath meningioma.

Inverted growth of transitional cell carcinoma in the ureter is reported. A 71-year-old female visited us for right flank pain and gross hematuria. Hematuria from the right ureteral orifice was found by cystoscopy. Intravenous pyelography revealed right hydronephrosis and a filling defect in the right ureter, but the filling defect moved to the lower ureter. Computerized tomographic (CT) scan demonstrated a tiny lesion in the right ureter. Under a tentative diagnosis of right ureteral tumor, flexible fiberoptic ureteroscopy was performed. As a pedunculated tumor with a smooth surface was found, biopsy was performed. Since pathological examination showed malignancy, right nephroureterectomy was performed. Histological diagnosis was transitional cell carcinoma, grade 1. Cancer was covered by normal transitional epithelium, and developed inverted growth. This is a rare case of inverted growth of the transitional cell carcinoma in the ureter.

A 71-year-old woman admitted to our hospital with complaints of progressive dyspnea on exertion and weight loss. Roentgenological examination demonstrated peripheral pulmonary fibrosis and a mediastinal tumor suggesting thymoma. The pathological findings of transbronchial lung biopsy (TBLB) confirmed pulmonary fibrosis. Moreover, cytomegalic inclusion bodies in TBLB and a high titer of serum CMV IgG antibody suggested pulmonary CMV infection. It is considered that pulmonary fibrosis and CMV infection were coexistent in this patient.

A 71-year-old man who had undergone a total cystectomy and a transureterocutaneostomy more than a year earlier was admitted to our hospital on February, 1992 because of the chief complaints of anorexia and systemic bone pain due to multiple bone metastases of bladder cancer. At two weeks after the admission, he had a sudden attack of dyspnea. His chest reontgenogram revealed no significant abnormalities. He had repeated attacks and died of respiratory failure two days after the first attack. An autopsy disclosed diffuse microscopic pulmonary tumor emboli in the pulmonary arteries and arterioles of bilateral lungs, but there was no parenchymal metastasis. The metastatic lesions in the sinusoids of the liver were also occupied by numerous tumor emboli, suggesting that the tumor emboli in the lungs had derived from those in the sinusoids. Microembolization of the whole lung area must be considered as a cause of clinically unexplained dyspnea.

A 71-year-old man underwent a completion pneumonectomy for a recurrent carcinosarcoma of the left upper lobe. A single lumen endotracheal tube was used for intubation. During dissection the right main bronchus became blocked by a tumor mass. Due to severe adhesions it was impossible to open the airway from inside the operation field. This neither was also not possible by bronchoscopic maneuvers and the patient died. The case is similar to six cases described in the literature since 1966 [4-7, 9, 10]. Recommendations for preventing and treating the complications are given.

Two cases of papillary ureteral end tumors, treated by transurethral resection are presented. Case 1: A 71-year-old female visited us for asymptomatic macroscopic hematuria. Cystoscopy revealed a papillary pedunculated tumor in the bladder protruding from the right ureteral orifice. Under a diagnosis of superficial tumor at the right ureteral end, transurethral resection was performed using a rigid ureteral resectoscope. Pathological examination revealed transitional cell carcinoma, grade 2 without muscular invasion. There is no evidence of recurrence after 25 months of follow up postoperatively. Case 2: On a routine cystoscopy after transurethral resection of bladder tumor in a 68-year-old male, papillary pedunculated tumors protruding from the right ureteral orifice were found. Under a diagnosis of superficial tumor at the right lower ureter, transurethral resection was performed using cold cup forceps and loop electrocoagulation. The tumor was transitional cell carcinoma, grade 1 without invasion. No evidence of recurrence was detected 15 months postoperatively. Transurethral resection of the ureteral tumor at the lower end appeared to be useful for the selected cases. The indications, complications and follow up for this procedure were discussed.

A 71-year-old woman was referred to our hospital for aortic valve replacement because of the vegetation of aortic valve. She had transient right arm weakness and aphasia in November 1991. On two-dimensional echocardiogram, she was found to have a mobile, pedunculated mass attached to the non-coronary cusp of the aortic valve. At operation, multiple frond-like tumor measuring 7*7 mm was found attached to the free-edge of the non-coronary cusp of the aortic valve. The aortic valve with this tumor was excised and replaced with a 21-mm Carpentier-Edwards prosthesis. Microscopic sections revealed the typical findings of a papillary fibroelastoma. The patient's postoperative course was unremarkable.

A 71-year-old man with prostate cancer developed epidural compression of the spinal cord caused by bony protuberances expanding from a vertebral osteoblastic metastasis. Pathologic examination of the metastatic lesion showed that both tumor and thickened vertebral trabeculae broke through the cortex and formed bony protuberances. The periosteal new bone appeared not to arise from a reactive periosteum but from the tumor breaking through the cortex. A biologic interaction between the tumor and the host may be responsible for the rare periosteal new bone formation.

A case of ureteral metastasis from renal cell carcinoma is reported. A 71-year-old man who had received radical nephrectomy for left renal cell carcinoma, G1 and about two years earlier presented with asymptomatic macrohematuria. He had received interferon therapy and surgical treatments for bone metastasis two times after the operation. Cystoscopic examination revealed bleeding from the left residual ureter but CT scan showed no abnormal findings. Left ureterectomy and partial cystectomy was performed and a small finger tip-sized tumor was found at 13.5 cm above the ureteral orifice. Pathological examination showed metastatic renal cell carcinoma, G1 > G2. Histologically and clinically, this tumor seemed to have metastasized by a hematological pathway. Seventeen cases of ureteral metastasis of renal cell carcinoma have been reported previously in the Japanese literature.

A 71-year-old woman developed complete third nerve palsy and total blindness of the right eye one month after completing a course of radiotherapy for sphenoid sinus carcinoma over a 13-month period. Differential diagnosis included recurrence of the tumor, radiation-induced second neoplasm, empty sella with chiasmal prolapse and secondary chiasmal arachnoid adhesions, and radionecrosis. Magnetic resonance imaging demonstrated gadolinium contrast enhancement of the right intracranial optic nerve and chiasm, suggesting a radionecrosis process.
