1/397. Lacrimal gland abscess: two case reports.

    BACKGROUND: Bacterial dacryoadenitis is rare and suppuration leading to abscess formation within the lacrimal gland has been very rarely reported in the antibiotic era. methods: The medical records and investigation results, including computed tomography (CT), of two patients with lacrimal gland abscess were reviewed. RESULTS: Two cases of lacrimal gland abscess, one a 28-year-old male and the other a 64-year-old female, are described. Both demonstrated a characteristic low-density area within an enlarged lacrimal gland on CT. The first case had been treated with antibiotics and the abscess, when drained, was sterile. The second case settled spontaneously. Neither patient suffered any sequelae of dry eye. CONCLUSIONS: Although rare, lacrimal gland abscess may still occur and may require surgical drainage if spontaneous resolution does not occur.

2/397. Seminal vesicle abscess due to tuberculosis: role of tissue culture in making the diagnosis.

    Abscess formation involving the seminal vesicle occurs rarely. We report a case of seminal vesicle abscess due to tuberculosis. urine and fluid cultures and histologic examination of the prostate were negative for mycobacteria. The cause of the abscess was confirmed only after tissue cultures were done.

3/397. Abscess formation as a complication of parenteral methylphenidate abuse.

    case reports of five patients suffering from either skin abscesses or cellulitis following parenteral methylphenidate abuse are presented. Four patients had similar lesions consisting of abscesses or cellulitis which demonstrated typical signs and symptoms of an infective process and were treated with local symptomatic therapy, incision and drainage if indicated, and systemic antibiotics. The fifth patient suffered from a circular, necrotic, nonpurulent ulcer on the dorsum of the right foot which produced no local or systemic toxic effects. Attempts to culture a responsible organism yielded streptococcus viridans, an organism which is normal flora of the skin and, although opportunistic, is generally considered nonpathogenic. These cases further substantiate the belief that local vasospasm, chemical irritation, or both, produced by the methylphenidate solution may primarily cause a necrotic ulcer susceptibble to secondary bacterial infection.

4/397. Peritoneal abscess formation as a late complication of gallstones spilled during laparoscopic cholecystectomy.

    The case is described of a 74-year-old woman who presented with an abdominal abscess 1.5 years after laparascopic cholecystectomy. CT and ultrasound showed the presence of gallstones within the abscess. Spillage of gallstones from perforation of the gallbladder is a well recognized complication of laparascopic cholecystectomy, although subsequent abscess formation is unusual especially after a long delay as in this case.

5/397. Endovascular occlusion of a carotid pseudoaneurysm complicating deep neck space infection in a child. Case report.

    Pseudoaneurysm formation of the cervical internal carotid artery (ICA) is a rare, potentially lethal complication of deep neck space infection. This entity typically occurs following otolaryngological or upper respiratory tract infection. The pseudoaneurysm is heralded by a pulsatile neck mass, Homer's syndrome, lower cranial neuropathies, and/or hemorrhage that may be massive. The recommended treatment includes prompt arterial ligation. The authors present a case of pseudoaneurysm of the cervical ICA complicating a deep neck space infection. A parapharyngeal staphylococcus aureus abscess developed in a previously healthy 6-year-old girl after she experienced pharyngitis. The abscess was drained via an intraoral approach. On postoperative Day 3, the patient developed a pulsatile neck mass, lethargy, ipsilateral Horner's syndrome, and hemoptysis, which resulted in hemorrhagic shock. Treatment included emergency endovascular occlusion of the cervical ICA and postembolization antibiotic treatment for 6 weeks. The patient has made an uneventful recovery as of her 18-month follow-up evaluation. Conclusions drawn.from this experience and a review of the literature include the following: 1) mycotic pseudoaneurysms of the carotid arteries have a typical clinical presentation that should enable timely recognition; 2) these lesions occur more commonly in children than in adults; 3) angiography with a view to performing endovascular occlusion should be undertaken promptly; and 4) endovascular occlusion of the pseudoaneurysm is a viable treatment option.

6/397. Pouch-sacral fistula three years after restorative proctocolectomy for ulcerative colitis.

    fistula formation after restorative proctocolectomy poses a challenge to the surgeon and sometimes can lead to the excision of the pouch. A 21-year-old female patient developed an ileal J-pouch-sacral fistula with abscess and osteomyelitis of the sacrum, more than three years after the pouch construction for ulcerative colitis. Two months prior to this event, the patient had a single and transient episode of pouchitis. The role of pouchitis in the aetiopathogenesis of the fistula is unclear. To our knowledge, the late development of such a fistula has not been reported previously.

7/397. Management of pelvic abscess during pregnancy: a case and review of the literature.

    Cases of pelvic or abdominal abscess complicating pregnancy are rare. Noninvasive diagnostic techniques including ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) have enabled early diagnosis of this unusual complication of pregnancy. We describe a patient in whom the diagnosis of a pelvic mass was made by sonography and MRI at 25 weeks' gestation. At laparotomy, a pelvic abscess was partially resected and drained. Two weeks later when the patient again became symptomatic, a recurrent pelvic abscess was detected by CT and treated with intravenous antibiotics and CT-guided transcatheter drainage. The patient's recovery was thereafter uncomplicated and she delivered a healthy male infant by elective repeat cesarean at 38 weeks' gestation. The literature concerning pelvic and abdominal abscesses during pregnancy is reviewed. The potential advantages of imaging-guided, percutaneous transcatheter drainage for the treatment of such patients are emphasized. TARGET AUDIENCE: Obstetricians & Gynecologists, family physicians. learning OBJECTIVES: After completion of this article, the reader will be able to understand the nonsurgical alternatives for the drainage of intraabdominal abscesses, the possible etiologies of intraabdominal abscess formation in the pregnant population, and the various approaches to percutaneous catheter drainage of intraabdominal abscesses.

8/397. Ultrasonographic evaluation of pericholecystic abscesses.

    Pericholecystic abscess formation is a serious complication of cholecystitis that develops after gallbladder perforation and is usually associated with acute inflammatory signs and symptoms. Ultrasonographic findings in three surgically proven cases of pericholecystic abscess are reported. The findings ranged from a well defined band of low-level echoes around the gallbladder to multiple, poorly defined hypoechoic masses surrounding an irregular, indistinct gallbladder outline. The former situation correlated with a well encapsulated pericholecystic inflammatory process, while the latter was associated with extensive abscess formation resulting from gallbladder rupture. cholelithiasis was identified in two of the three cases. Ultrasound for preoperative detection of pericholecystic abscess is discussed.

9/397. Three cases of arcanobacterium haemolyticum associated with abscess formation and cellulitis.

    arcanobacterium haemolyticum has been described as an unusual pathogen causing pharyngotonsillitis and systemic disease in patients with predisposing conditions. A case of soft tissue abscess with no apparent portal of entry is reported in a healthy 31-year-old man who presented with a breast tumor. A second case of abscess formation in a 50-year-old patient with complicated wound healing is presented. In addition, a case of arcanobacterium haemolyticum cellulitis in a 25-year-old female is reported. Due to its innocuous, coryneform appearance, this pathogen is probably underreported; therefore, the diagnostic evaluation of this organism is emphasized.

10/397. Computed tomography and 67Ga citrate radionuclide imaging for evaluating suspected abdominal abscess.

    A retrospective analysis of the results of 67Ga citrate radionuclide imaging and computed tomography (CT) in 45 patients with suspected abdominal abscess was conducted to determine the mertis of each method. Both techniques were highly sensitive in detecting abdominal abscesses, and often provided complementary and supplementary diagnostic information; their combined use many times offset the limitations of each method used alone. Guidelines are suggested that permit rapid evaluation, while limiting diagnostic errors, when using 67Ga citrate radionuclide imaging and CT in the presence or absence of localizing symptoms and signs.
