Detection and localization of nonmetallic intraocular foreign bodies by magnetic resonance imaging.

Computed tomography (CT) is useful in detecting metallic intraocular foreign bodies. Magnetic resonance imaging (MRI) is a technique that might allow the detection and localization of nonmetallic intraocular foreign bodies. We performed CT and MRI scans on ten freshly enucleated sheep eyes, eight of which contained nonmetallic intraocular foreign bodies of wood, glass, plastic, or rock. Computed tomography correctly detected seven of eight foreign bodies, while MRI detected all eight of the foreign bodies. Computed tomography is necessary to determine the presence of a metallic foreign body, but when the CT scan is negative, MRI may still detect small nonmetallic foreign bodies.

Penetrating transorbital foreign body with ocular preservation.

Large penetrating transorbital foreign bodies may initially appear to be of a devastating character to the ocular tissues. However, several reports of such large foreign bodies have proved to spare the eye. A case report of a large wooden foreign body with transorbital penetration into the right frontal lobe is reported. The globe remained intact and was only displaced, with a final visual acuity of 20/40. However, complete ophthalmoplegia and ptosis persisted. A low pressure hydrocephalus ensued following intracranial debridement.

[Small foreign bodies in the lungs of children--treatment or observation?].

The diagnosis of foreign body aspiration may easily be missed. Three children younger than three years of age inhaled, respectively, popcorn, a plastic pearl, and a piece of tape to the lungs. The children were admitted to the paediatric department under strong clinical suspicion of foreign body inhalation, but were discharged with minor symptoms and after normal X-ray investigation. Two of the children expelled their foreign body (tape and popcorn) after three days and three weeks, respectively, whereas the plastic pearl was removed by bronchoscopy after six months. X-ray investigation of the lungs are of limited value in the exclusion of presence of small inhaled foreign bodies. Children with minor symptoms suspected of having inhaled foreign bodies may possibly be observed for a short period in order to see if the foreign body is expelled spontaneously. However, the children should be carefully followed up, and bronchoscopy should be considered at all times.

The histopathology of different foreign-body reactions in oral soft tissue and bone tissue.

Foreign bodies may be endogenous or exogenous and provoke chronic inflammation of the foreign-body type. The reaction provides a mechanism for elimination of the foreign body and the reaction pattern depends on the kind of tissue involved. In soft tissues there is cellular inflammation and fibrous encapsulation with macrophages. In bone, during the healing period, biomechanical factors determine whether a fibrous encapsulation or a bony covering develops demarcating the foreign material. The particular characteristics of the foreign-body reaction in bone explain the success of dental and orthopaedic implants.

Genital foreign bodies: more than the eye can see.

Genital foreign bodies constitute a diverse but surprisingly common means of presentation to emergency departments. Although the presentation usually means the initial diagnosis is easily made, we present a case here that stresses the importance of attention to history, clinical examination and radiological investigation. A 44-year-old gentleman presented with a history of pain and discharge from a self-inflicted scrotal wound. Further questioning revealed a history of genital foreign bodies, but the full extent of his condition was not apparent until plain pelvic radiographs were obtained. The initial management of genital foreign bodies follows basic surgical principles. Constricting bands must be removed, devitalized tissues debrided and the surgical field extensively irrigated. Underlying psychiatric illness may be present and a high index of suspicion is required in the initial assessment of such patients. A plain pelvic radiograph is recommended to fully identify all foreign bodies present.

Fungus implantation with wooden intraocular foreign bodies.

Four cases of wooden intraocular foreign bodies are presented. In each case the foreign body was found to be contaminated by fungi which may have contributed to the intraocular inflammatory response but did not actively invade ocular tissues. Tolerance of the eyes to the retained wooden material was very poor.

Unusual presentations of penetrating foreign bodies of the upper aerodigestive tract.

Only a small number of ingested foreign bodies perforate the esophagus and even a smaller fraction migrate extraluminally. Four such penetrating and migrating foreign bodies of the upper aerodigestive tract are presented. Review of the literature revealed 321 cases of penetrating ingested foreign bodies, of which 252 remained intraluminal and 43 were found extraluminally, with the status of the remainder indeterminate. Analysis revealed that an intraluminal penetrating foreign body carried a higher overall mortality than one that migrated extraluminally. Although intraluminal and extraluminal penetrating foreign bodies may remain quiescent for years before presenting a complication, no correlation existed between mortality and the duration of the foreign bodies' retention. The greatest mortality was seen with vascular complications followed by diffuse and local suppurative processes. The overall mortality was significantly reduced in the post-antibiotic era.

Imaging diagnosis: magnetic resonance imaging of a cervical wooden foreign body in a dog.

This article describes the discovery of a chronic cervical wooden foreign body ventral to the left transverse processes of the cranial cervical spine using magnetic resonance imaging (MRI) in a dog that presented with chronic neck pain and lameness. The dog did not exhibit dysphagia or chronic draining tracts, the most common signs of the presumed cause, that of a penetrating oropharyngeal foreign body. The foreign body itself was represented on MR images as an oval straight-edged core within an inflammatory tissue reaction. The wood was slightly hyperintense on T2- and isointense on T1-weighted images relative to muscle. Surrounding this was a more conspicuous contrast-enhancing reactive tissue rim that was hyperintense on all pulse sequences. Adjacent musculature also exhibited diffuse edema and contrast enhancement that extended around the left cervical vertebral transverse processes and local intervertebral nerve roots. The foreign body was found to be a wooden stick upon surgical removal. MRI is an excellent method for visualizing the inflammatory tissue reactions associated with soft-tissue foreign bodies because of its contrast resolution and depiction of anatomy in multiple imaging planes.

[Pseudotumor-like superficial conjunctival foreign body].

Pseudo-tumoral presentation of a superficial conjunctival foreign body. A 4-year-old girl was seen in consultation for an apparent conjunctival tumor of the inner canthus of the right eye. With a soft traction, the tumor was detached of the conjunctiva, as it represented in fact a foreign body. Histopathology helped to diagnose that the foreign body was made of textile fiber. Superficial conjunctival foreign bodies may sometimes appear difficult to identify primarily especially in children.

Migrating foreign bodies in the upper digestive tract.

Migrating foreign bodies in the aerodigestive tract are not so uncommon. Two cases of penetrating and migrating extraluminal foreign bodies in the upper aerodigestive tract are presented. Both patients had ingested fish bones. Fish bones are the commonest of bones to be ingested. Sharp and pointed fish bones are more likely to penetrate extraluminally. A high index of suspicion is necessary to institute early treatment. A CAT scan is invaluable in locating the foreign body especially with regards to surgical landmarks at exploration. Early surgical intervention avoids life-threatening complications.

Intralenticular intraocular foreign body after stone impact: CT and US findings.

INTRODUCTION: Intraocular foreign body (IOFB) is a relatively common entity in emergency departments worldwide. Appropriate ocular assessment is mandatory if an intraocular foreign body is suspected because it is associated with an increased risk of endophtalmitis and a wide range of complications including hyphaema, cataract, vitreous hemorrhage, and retinal tears and detachment. CASE REPORT: We present a case of intralenticular intraocular foreign body after stone impact. DISCUSSION: Ultrasonography (US) and computed tomography (CT) show an accurate location of the foreign body inside the lens. This finding enabled the surgeon to perform a phacoemulsification lens extraction with removal of the foreign body, the optimal method of removing intralenticular IOFB. To our knowledge, this is the first US and CT imaging report.

Ingestion of unusual foreign bodies and malrotation: a "perfect storm".

Management of foreign body ingestion is usually nonsurgical unless atypical foreign bodies or anatomical variants are suspected. The present article illustrates a case of atypical foreign bodies ingestion in the presence of intestinal malrotation. The patient required surgical treatment and had an uneventful postoperative recovery. The article also reviews the cases reported in the literature of magnetic ingestion and the possible complications associated with it.

Foreign bodies of the esophagus.

The incidence of esophageal foreign bodies is probably declining. The majority of patients are still in the pediatric age group. Clinical history and radiologic studies usually establish the diagnosis. Rigid esophagoscopy is still the standard method of therapy, but alternative methods can be employed with proper patient selection. The practicing physician must be familiar with the advantages and disadvantages of available methods of therapy. Observation for up to 24 hours is probably safe, and the proper method of therapy must be carefully selected according to the age of the patient, the type of the impacted foreign body, the location of impaction, the duration of impaction, and the available medical resources and skills. Major complications are to be expected with prolonged or missed impaction of foreign bodies in the esophagus. Prevention, high index of suspicion, and early treatment are important factors that can decrease the possible complications of impacted foreign bodies in the esophagus.

Early and late stages of foreign-body carcinogenesis can be induced by implants of different shapes.

Implanted foreign bodies of certain shapes, especially large non-perforated polymer films, induce subcutaneous sarcomas in a high percentage of mice and rats; in contrast, implants of other shapes, e.g., perforated or minced films or Millipore filters with 0.45 microns pores, are non-carcinogenic or only weakly carcinogenic. Experiments described in this report have shown that when carcinogenic non-perforated film was removed at 3.5 months after implantation and one of the "non-carcinogenic" foreign bodies listed above was implanted into the same subcutaneous sites, a high percentage of sarcomas was induced. The same non-carcinogenic or weakly carcinogenic foreign bodies implanted in the mice after total body gamma irradiation or after single injection of ethylnitrosourea induced subcutaneous sarcomas in significantly higher percentages of animals than the same foreign bodies implanted in control mice. Our data suggest that foreign bodies of "non-carcinogenic" or "weakly carcinogenic" shapes can act as efficient promoters of subcutaneous carcinogenesis initiated by other agents such as implanted "carcinogenic" foreign bodies, ionizing radiation or chemical carcinogen.

Radiologic evaluation of foreign bodies.

The correct selection of a radiologic imaging modality along with knowledge of indirect radiologic findings can help determine the presence and location of a foreign body. Plain radiographs should be the initial screening modality for a suspected foreign body. Whereas most metal and glass foreign bodies are detectable on radiographs, many foreign bodies, including wood, are not. We do not advocate using xeroradiography for the detection of foreign bodies. When a suspected superficial foreign body is not delineated on radiographs, ultrasonography should be the next modality of choice. CT should be reserved for deep foreign bodies or when foreign bodies are not seen on radiographs or ultrasonography but are suspected.

Ultrasound in the emergency department: detection of wooden foreign bodies in the soft tissues.

Detection of a soft tissue foreign body is often very difficult, even when strongly suggested by history and physical examination. Plain radiography is helpful only in cases where the foreign body is radiopaque. Wood, which is usually radiolucent, can go undetected if further imaging is not considered. Undetected wooden foreign bodies can cause significant morbidity, repeat visits, high cost, and extensive surgery. Reported here are four cases in which ultrasound was used in the Emergency Department to detect and remove wooden foreign bodies from the soft tissues. These reports suggest that ultrasound is a clinically useful tool for the detection and removal of wooden foreign bodies by emergency physicians.
