33-year follow-up after simple excision of a giant renal oncocytoma with calcifications: case report and review of the literature.

Renal oncocytoma can present with calcification seen on the plain roentgenogram. From a review of the literature (both before and after 1976, when the concept of oncocytoma was popularized in the English literature), 10 cases of calcification in association with renal oncocytoma were found. In three of these 10 cases, the calcifications could be grossly demonstrated on the plain roentgenogram; in the other seven cases, the calcifications were microscopic in nature. The presence of calcification in a renal tumor does not rule out the diagnosis of oncocytoma. Grossly, a renal oncocytoma has a brownish mahogany color. A case is presented in which simple excision of an oncocytoma resulted in a 33-year survival. In the future, excision instead of nephrectomy could become the standard treatment for these tumors.

Lithiasis in the ileal conduit and the continent urinary pouch: two cases and a review.

We present 2 patients who developed stones (6 and 57 g) in the ileal conduit; the first stone was passed and the second required surgical removal; its nidus was a surgical staple. After a review of the literature which includes 25 other cases of stones in ileal conduits, as well as over 20 cases of stones in continent urinary pouches, it is concluded that the use of metallic staples in the construction of the ileal conduit or the continent urinary pouch should be abandoned.

Sacral osteoid osteoma in a 10 year old girl.

We report the case of a ten year old female student who complained of chronic back pain and morning stiffness of several months duration. She failed to respond to non-steroidal anti-inflammatory drugs (NSAIDS). Further investigations which included bone and CT scan revealed the presence of an osteoid osteoma at the first sacral vertebra (S1 vertebra). The patient made an excellent recovery after surgical excision.

Treatment options in primary Ewing's sarcoma of the spine: report of seven cases and review of the literature.

Primary Ewing's sarcoma of the spine is reviewed, and seven cases are presented. Ewing's sarcoma of the spine is a rare condition that appears with a clinical triad of local pain, neurological deficit, and a palpable mass. The clinical picture, imaging characteristics, and management are discussed. The definitive management of Ewing's sarcoma of the spine, as in other locations, could include three main modalities: surgery, radiotherapy, and combination chemotherapy. In the presence of acute neurological decompensation, decompressive surgery via an appropriate approach should be performed. Because Ewing's sarcoma is usually sensitive to chemotherapy, initial chemotherapy, in neurologically stable patients, could be attempted first without surgical resection. Further management could then be gauged according to the response.

Traumatic intracranial aneurysms caused by missiles: their presentation and management.

Only 30 cases of traumatic intracranial aneurysm (TICA) secondary to missile injury have been reported to date. To these we add 15 more cases. Missile TICAs are often seen on a secondary branch of the middle cerebral artery and are usually accompanied by a intracerebral hematoma (80%) or by an acute subdural hematoma (26%). Fourteen of our cases were secondary to shrapnel injuries and only one was secondary to a bullet. None of the injuries was through-and-through. TICAs may enlarge in time and, seemingly inoffensive, may rupture and lead to death. All seven TICAs studied histologically proved to be false aneurysms. TICAs are best treated through trapping and excision. The outcome depends on the patient's status and level of consciousness before surgery. Indications for angiography are discussed.

Intracranial infection after missile injuries to the brain: report of 30 cases from the Lebanese conflict.

This study reviews the features of 30 intracranial infections complicating 600 penetrating head injuries from missiles in patients treated at the American University of Beirut Medical Center between 1981 and 1988. The follow-up period ranged from 1 month to 7 years (mean, 2.5 years). Sixteen patients had a brain abscess, 9 had cerebritis, 2 had an infected intracerebral hematoma, and 5 had meningitis. Infection developed 4 days to 7 years after the initial debridement. The infecting organisms were Gram positive in 11 patients (36%), Gram negative in 12 (40%), and a combination of Gram positive and Gram negative in 2 (7%). Twenty-four patients (80%) had wound dehiscence or cerebrospinal fluid leakage at the time the infection appeared. There was a 76% correlation between the organisms cultured from the dehiscent scalp wound and the brain. Twenty-three patients had intracranial retention of bone. Infection developed in 16 of the 30 patients (70%) around bone fragments, in 4 around a metallic fragment, in 2 around absorbable gelatin sponge, and in 3 along the missile tract; 2 had an infected intracerebral hematoma, and 3 had meningitis. At least one of the following risk factors was present in each patient: extensive brain injury, coma, trajectory through an air sinus, cerebrospinal fluid fistula, inadequate initial debridement, or incomplete dural closure. The incidence of intracranial infection in patients with postoperative retention of bone was 4% in the absence of scalp wound dehiscence, compared with 84.6% when wound dehiscence was present. Ten patients (43%) still retained a bone fragment measuring less than 1 cm after excision of a brain abscess or treatment of cerebritis or meningitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Postprostatectomy lithiasis.

After a short historical survey and a comprehensive review of the world literature which comprises 242 cases (including 19 personal ones), 10 new cases of lithiasis after prostatectomy are added (5 of which are personal ones), making a total of 252 cases. The CT scan was very useful in the diagnostic imaging. In appropriate situations, the use of the stone basket was found advantageous. In patients who are at risk of developing stones after prostatectomy, great care should be exercised both during the operation and in the postoperative period.

Neuropathic bladder in ankylosing spondylitis with spinal diverticula.

Cauda equina type of syndrome with neuropathic bladder is a rare but known complication of long-standing ankylosing spondylitis. From 1968 until now, diverticula from the subarachnoid space eroding into the bodies of the lumbosacral vertebrae have been reported in 46 cases of ankylosing spondylitis with cauda equina syndrome and neuropathic bladder. We report 3 cases of neuropathic bladder and ankylosing spondylitis with cauda equina symptoms. In 1 of the 3 patients, these rarely encountered spinal diverticula were demonstrated by computerized tomography (CT) scan. The etiology of these diverticula and their treatment are reviewed.
