[Hemangioblastoma of the cauda equina--a case report (author's transl)].

We reported the case of a 40-year-old man who was hospitalized to our department on November 16, 1975 with a year history of neuralgia in the saddle region and vesicorectal dysfunction. Examination of CSF on lumbar puncture at L4-5 revealed xanthochromia with a protein content of 2,560 mg/dl. Myelography revealed a tortuous filling defect at the level of L2 coupled with complete blockade at L3 level. Selective spinal angiography of the left 12th intercostal artery demonstrated the enlarged Adamkiewicz's artery. This blood vessel was found to enter a diffuse uniform density, where no distinct blood vessels were visible. Within one second after the injection of contrast agent an efferent vein appeared from the right side of the density, ascended to the level of Th12 and then, upon turning, descended to the pelvic canal. These findings suggested a hemangioblastoma of the spinal cord. Laminectomy was performed at levels of L2 through L4 and a hemangioblastoma of the cauda equina was totally excised at L3 level. Although the postoperative course was complicated by a transient dysuria and hypesthesia at S1-S5 levels, complete cure was achieved in a month. In the present paper clinical features and neuroradiological examination of a hemangioblastoma of the spinal cord were described.

[Spontaneous regression of sinus pericranii--report of a case (author's transl)].

Spontaneous regression of sinus pericranii has not been reported in the literatures. The aurthors presented a very rare case of sinus pericranii, which was diagnosed as early as nine days after birth and completely disappeared in seven years. The patient was a nine-day-old boy from normal delivery in full term, who had a soft tumor simulating cephalhematoma in the right parietal region. The overlying scalp looked like a hemangioma bitemporally connecting with strikingly dilated scalp veins. Soft X-ray examination of the skull revealed a homogenous mass and a small bone defect beneath the mass. Venous blood was punctured from the tumor. By means of direct injection of contrast media into the tumor, the superior sagittal sinus as well as many extracranial varicositous veins were shown. No intracranial vascular anomaly. In a year the tumor spontaneously declined and in the following seven years it disappeared completely. Pathogenesis of this lesion was discussed with special reference to cephalhematoma and a possibility of spontaneous regression of sinus pericranii was stressed.

Large cholesterol polyp of the gallbladder mimicking gallbladder carcinoma.

Gallbladder tumors larger than 10 mm in diameter have a high incidence of malignancy. We report an extremely rare case of a large cholesterol polyp of the gallbladder mimicking gallbladder carcinoma. Ultrasonography and computed tomography showed a larger papillary mass in the fundus of the gallbladder with a maximum diameter of about 30 mm, the largest gallbladder polyp ever reported to our knowledge.

Colon stenosis caused by old portal vein thrombosis.

A 58-year-old female with a history of portal vein thrombosis was referred to our hospital with abdominal pain and distention. Colon fiber and enema of the colon showed stenosis at the transverse colon and the ascending colon, with edematous mucosa. Laparotomy revealed no abnormal findings other than chronic ischemia of the colon. To our knowledge, this is the first reported case of colon stenosis caused by portal vein thrombosis.

Postoperative radiation therapy for esophageal cancer.

The value of postoperative radiation therapy (RT) was investigated in 77 patients with esophageal cancer resected between 1977 and 1986. Surgical resection was palliative in 13 of these patients. Although seven of them underwent postoperative irradiation to the residual tumor, all of the patients died within one year. Following potentially curative resection performed in 64 patients, 31 patients received 50 Gy of postoperative RT to the lower neck and the mediastinum (group Ia), seven were unable to receive full-dose postoperative RT (group Ib), and 26 were not treated with postoperative RT (group II). The 5-year survival rate estimated by the Kaplan-Meier method was 54% for group Ia, 29% for group Ib, and 33% for group II, with the difference between groups Ia and II being significant (p less than 0.025). The local recurrence rate in the mediastinum was lower in group Ia than in group II. Prophylactic postoperative RT for esophageal cancer is a safe and effective regimen for patients with resected disease.
