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.

An unusual cause for trigeminal neuralgia: contralateral meningioma of the posterior fossa.

Twenty cases of facial neuralgia associated with tumors of the contralateral posterior fossa were collected from the world literature. Only four of these conform to the description of typical trigeminal neuralgia. We report on a fifth such case with a critical review of the literature. Subtotal excision of the tumor improves the pain and may convert a carbamazepine-resistant neuralgia into a responsive one. Total excision is often followed by a cure. Faced with such a case, the tumor should always be excised first, as this usually cures the neuralgia. Surgical treatment of the neuralgia in the presence of the tumor may be followed by disastrous results. An alternative hypothesis to the pathogenesis of the contralateral neuralgia is presented.

Mucinous adenocarcinoma of prostate.

The twenty-eighth case of mucinous adenocarcinoma of the prostate is reported. This microscopic variety of prostatic cancer is rare and aggressive; it metastasizes to bone, does not seem to respond to hormone therapy, and reacts positively to immunoperoxidase stain.
