Patients with clinically suspected anorectal sepsis were studied using MRI in order to determine if T2 weighted sequences with fat suppression conveyed any additional benefit over conventional short tau inversion recovery (STIR) sequences. 23 consecutive patients (16 male) undergoing MRI for suspected perianal sepsis were studied prospectively using a 1.0 T whole body system and body coil. Axial and coronal T1 weighted turbo spin echo sequences were obtained, followed by STIR and T2 weighted spectral fat saturation inversion recovery (SPIR) sequences. Images were assessed for the presence of sepsis or fistula, and information provided by the sequences compared. Active disease was diagnosed in 17 patients, 14 of whom had fistula-in-ano; one intersphincteric, 10 transsphincteric and three extrasphincteric. Internal openings were identified in all of these 14 patients; anal in 10, rectal in two, and both in two. Diagnosis and fistula classification was possible in all of these 14 subjects on the basis of STIR sequences alone. The anal sphincters and pelvic floor musculature were better resolved by STIR than SPIR, leading to easier and more confident determination of fistula anatomy in eight of the 14 (57%). In no case did STIR sequences fail to resolve inflammation seen subsequently on SPIR, despite reduced track intensity. T1 weighted sequences were generally non-contributory. Both STIR and SPIR sequences are adequate to classify fistula-in-ano, but classification was easier with STIR due to superior resolution of pelvic floor structures.

Patients in rest-homes, intensive care units, long hospitalization and dialysis and whoever stays in a hospital continuously or occasionally for long periods of time may run into the well-known and typical complications of prolonged hospitalization. We have studied the urologic aspect in all the cases of the Medical- Surgical Emergency Institute in the Hospital of Ancona (seated in Torrette), over the period 1990-96, in patients hospitalized for at least 30 days. All the patients were followed and studied with the same method, though taking into account their different pathological conditions. They were treated by the same medical and paramedical staff. The same antibiotic therapy and the same checkup were adopted for all of them. We have noticed that out of 122 patients the most frequent pathologies have been urinary infections (19%); while sepsis with different pathogenesis was recorded in 4% of the patients. The method of study applied during and after the hospitalization was used also in rehabilitation centres and included: urologic examination, rectal touch (in men), direct X-ray of the abdomen, ultrasound of the urinary tract, X-ray urography, if required; moreover urodynamic examination, MRI of encephalon and spinal marrow in patients with neurological lesions. The catheter was removed in all the patients and none of the following conditions were observed: vesical lithiasis, abscesses, fistulae in penoscrotal angle, urethrostenosis, injuries to renal emunctory. In conclusion we believe that the functional symptoms of minction--be they of obstructive or irritable nature--are not existent and that the urologic prognosis in long term patients in excellent, provided that prophylaxis is carried on against hospital urinary infections as their occurrence is very frequent and therapy is expensive. It can also be stated the patient hospitalized in ICU will not present damages to the urinary tract, even if he/she has been hospitalized because of injuries to the urinary tract, provided that the urologic tutoring, together with the action of the physician handling the Emergency, follow the rules for asepsis, the best biocompatible materials are use, infections are monitored, the extensions of cerebrospinal injuries are examined and therapeutic axioms, such as barren and clean intermittent catheterism, are finally adopted.

Two patients, aged 22 and 68, were admitted for recurrent orchi-epididymitis and septicemia respectively. On digital rectal examination, a right pararectal mass was palpated. CT showed in both patients unilateral renal agenesia with a dilated blind ectopic ureter and an enlarged pseudocystic seminal vesicle. MRI obtained in one patient demonstrated a hyperintense content of the blind ureter and the seminal vesicle. Cross section imaging findings were in agreement with deferentography. Histology confirmed the diagnosis of renal dysplasia, with a blind ectopic ureter, opening in the seminal vesicle.

We report a 57-year-old woman with progressive gait disturbance and mental deterioration. She was well until March 1995, when she was 54 years of the age. At that time she noted a gradual onset of tremor and difficulty using her hand. Similar symptoms appeared in her right hands, and she visited another hospital, where 300 mg of levodopa and 7.5 mg of bromocriptine were prescribed. These medication did not help her symptoms. In the summer of 1996, she became to fall down easily. In September of the same year, she started to repeat the same words many times. She was unable to stop it. She was hospitalized to our service on January 25, 1997. On admission, she was alert but demented moderately; her Hasegawa dementia scale was 15/30. She showed palilallia, logoclonia, and echolalia. She showed constructional apraxia and questionable left-right disorientation. She had marked vertical gaze palsy with preserved oculocephalic response. She had masked face and small voice. Her gait was wide based with small steps. No muscle atrophy or weakness was noted. She showed only mild rigidity in the neck, but no rigidity was noted in the limb. No tremor was noted. She was bradykinetic. Deep tendon reflexes were symmetric and within normal limits. Laboratory findings on admission was unremarkable. MRI showed atrophy of the brain stem as well as cerebral cortical areas, particularly in the fronto-temporal region. Her hospital course was complicated with paralytic ileus and septicemia. She developed hypotension and pronounced dead on July 28, 1998. She was discussed in the neurological CPC. The chief discussant arrived at a conclusion that the patient had progressive supranuclear palsy and died of septic shock. All the participants wondered between PSP and CBD, but majority agreed with this diagnosis of the chief discussant. Only one thought that she might have had corticobasal degeneration rather than PSP, because of dementia, cortical atrophy in MRI, and lack of limb rigidity. Postmortem examination revealed cortical and brain stem atrophy. In the premotor cortex, marked astrocytosis and ballooned neurons were seen. Furthermore, astrocytic plaques were seen; this is considered to be pathognomonic for CBD. The substantia nigra showed marked neuronal loss and gliosis, but no neurofibrillary tangles or Lewy bodies were seen. Gliosis was also seen in the globus pallidus and in the medial thalamus. The pathologic diagnosis was corticobasal degeneration. This patient was very interesting case, in that the clinical manifestations appeared to be consistent with PSP, yet pathologic diagnosis was CBD. Lack of limb rigidity may be atypical for advanced PSP. In addition, palilalia appears to be more associated with CBD.

A preterm infant, whose course was complicated by sepsis, necrotizing enterocolitis with jejunal perforation, intraventricular hemorrhage and cerebellar hemorrhage, suffered permanent and total paralysis below the neck from extravasation of parenteral nutrition fluids through a femoral venous catheter. MRI imaging revealed extravasation of fluid into the paraspinus musculature with extension into the spinal canal. This fluid was identified as hyperalimentation and intralipid. Postmortem examination found evidence of necrosis of the spinal cord as well as perforation of the right iliac vein.

Pyomyositis is a primary bacterial infection of skeletal muscle. This infection tends to occur in the large muscles of the lower extremity. Pyomyositis of the proximal muscles of the thigh can simulate acute abdominal disease. Early diagnosis improves the outcome. Delayed diagnosis may lead to septicemia and shock. We report the CT and MRI findings in a patient with pyomyositis of the proximal muscles of the thigh.

A 51-year-old woman underwent emergency laparoscopic cholecystectomy. Stone loss occurred during gallbladder dissection. Histology showed empyema of the gallbladder. Postoperatively, she developed a subhepatic abscess that required percutaneous drainage. Two years after surgery, she re-presented with a right paracolic abscess. Transsciatic CT-guided drainage of the abscess was performed. Barium enema excluded colonic pathology. Two weeks later, she developed a right gluteal abscess deep to the recent drain site. Ultrasound-guided drainage was performed followed by a sonogram. The sonogram ruled out communication with the peritoneum. Two further subhepatic abscesses occurred during the next 5 years; the first abscess was drained percutaneously, but the second required open drainage: At laparotomy, gallstone fragments were found within the abscess cavity. The site of the previous gluteal drain continued to discharge intermittently. An MRI scan showed an uncomplicated sinus track. Subsequent sinography of the right gluteal track demonstrated an opacity at the apex of the sinus. The sinus was laid open and a gallstone retrieved. The patient has remained well for 3 years. Complications due to gallstone spillage generally manifest themselves shortly after surgery. This case demonstrates that lost stones may cause chronic abdominal and abdominal wall sepsis. In cases of chronic abdominal sepsis after laparoscopic cholecystectomy, the possibility of lost stones should be considered even if stones are not positively shown on imaging.

50 consecutive patients presenting with facial swelling thought clinically to be due to salivary gland disease underwent MRI. Examinations were interpreted by one radiologist without access to previous investigations. Records were reviewed to determine the reliability and role of MRI in patient management, and the contribution of other prior or subsequent investigations. MRI findings were verified against operative findings, percutaneous biopsy or clinical follow-up (periods ranging from 8-58 months). A mass was found in 27 patients; in 11 of these patients, disease was extrinsic to the salivary gland. MRI diagnosis of tumour was correct in all patients and MRI was a reliable investigation for planning surgical resection. No mass was found in 23 patients, 8 of whom had normal appearances. Evidence of salivary duct dilatation was seen in 12 patients and fatty infiltration was seen in 3. MRI findings appeared correct in all patients. Prior investigation was undertaken in 29 patients, including orthopantomography, ultrasound and sialography; none provided additional information. Sialography was carried out in three patients after MRI and concurred with MRI in all cases. MRI was an adequate basis for management in all patients and therefore appears to be an effective first line investigation of facial swelling. It is reasonable for patients to undergo preliminary investigation for dental sepsis, this being the most common cause of facial swelling. Further study is required to determine whether MRI can completely replace invasive sialography.

In 1945 a 6-year-old girl received a tangential gunshot injury to the left posterior inferior skull. After hospitalisation because of septicemia she was unable to walk for several months. Since 1967 she had been repeatedly applying for compensation because of pseudoneurasthenia and residual ataxia and many medical examinations were performed including X-ray, CT and MRI. Although certain objective findings (e. g. cerebellar atrophy) could be verified, a causal connection between the gunshot injury and the clinical findings could not be established. Therefore previous investigators concluded on a vascular origin of the disease. During the present re-examination of the patient, the authors found patch-like scars at the left posterior inferior skull base and behind the left ear, a cord-like scar formation in the subcutaneous tissue, connecting both skin scars, a gutter-like defect in the left occipital base of the skull and an indention of the left mastoid process, both again in line between the skin scars and a large defect of the left cerebellar hemisphere. It could be concluded with certainty that the anatomical findings and the clicinal symptoms were the direct result of a gunshot injury. Previous investigations had failed because of deficient investigations and techniques. In addition to an anatomical reconstruction, three dimensional reconstructions from CT scans proved most helpful.

Our purpose was to investigate the role of diffusion imaging (DI) in central nervous system (CNS) infections in pediatric patients. It was anticipated that DI would be more sensitive than conventional MRI in the detection of the infarctive complications of infection, and possibly, in the detection of the infectious process as well. Seventeen pediatric patients, eight having meningitis,, five with herpes encephalitis, three with brain abscess or cerebritis and one with sepsis, were evaluated at 1.5-T with DI. All herpes patients had positive DI at the site of herpetic involvement, and two had the addition of watershed infarctions. DI demonstrated more lesions in three of the four cases of herpetic encephalitis. Half the meningitis cases had watershed infarction where DI was better and half had vasculitic infarctions in which DI was equal to or better than conventional MRI. Diffusion imaging was more sensitive than conventional MRI alone in detection of changes due to infections and ischemic lesions, but did not differentiate between them by DI or apparent diffusion coefficient (ADC), although anatomic distribution of lesions proved useful.
