“…When left untreated, they can cause infection, inflammation, tendon or nerve injury, and allergic reaction. 5,7,8 Sonography is well established as an accurate method for diagnosing clinically suspected foreign bodies, and realtime sonographic visualization can guide surgical removal. [1][2][3][4]9 When the clinical history and sonographic findings are positive for a foreign body, no further imaging workup is needed.…”

Objective. To show the value of sonography in the detection of clinically unsuspected foreign bodies appearing as soft tissue masses. Methods. High-resolution B-mode and color Doppler sonography was performed in 288 patients referred with superficial soft tissue masses over a period of 2 years. Results. In 8 lesions in 6 patients, sonography showed small curved or linear echogenic structures surrounded by hypoechoic masses characteristic of foreign bodies with granulation tissue. One lesion had increased vascularity on color Doppler sonography. Patients were referred for other imaging studies, including magnetic resonance imaging, computed tomography, and bone and labeled red blood cell scintigraphy, which did not add relevant information. Three patients underwent surgery; foreign bodies were found in 2, and infected granulation tissue was found in 1. Spontaneous resolutions and no growth of the lesions were seen in the other 2 patients. Conclusions. The possibility of a foreign body should be considered when scanning soft tissue masses even in the absence of a relevant clinical history. Once a foreign body is diagnosed, no further workup is indicated.

“…A foreign body can be revealed on an image when its radiodensity (beam attenuation) vary sufficiently from that of the adjacent structures. However, when the size of foreign body gets smaller, the spatial resolution of imaging system also affects its detection (13)(14)(15).…”

Background and aim: Entrapment of foreign-bodies is a common phenomenon in traumatic events occurring in the maxillofacial region. The purpose of this study was to evaluate the efficiency of panoramic, CT, Cone-beam CT, MRI and ultrasonography in detecting different foreign-bodies in the maxillofacial region. Methods: Four different materials were used as foreign-body including metal, glass, rubber and wood. These particles were prepared in four different sizes from 2*2*2 mm to 5*5*5 millimeters. The foreign-bodies were then implanted into a sheep's head in the infraorbital part of maxilla and mandibular buccal region. The panoramic, CT, Cone-beam CT, MRI and ultrasonography were obtained from the model and the images were blindly observed and analyzed by two radiologists. A four-point scale was used to interpret the visibility of found foreign-bodies. Results: CT had the best efficiency in detecting different foreign-bodies. Cone-Beam CT was the next useful technique. The ability of differentiating the foreign-bodies from the adjacent structures were poor in MRI and ultrasonography. As expected, the panoramic was only efficient in detecting metallic bodies. Conclusion: CT-scan can be introduced as the best imaging modality in detecting different foreign-bodies especially non-metallic ones. CBCT is also acceptable for metal, glass and rubber particles.

Spontaneous migration of bullet from arm to forearm and its ultrasound guided removal

et al. 2013

Spontaneous migration of a retained bullet is rare. We are presenting here a case of a 24-year-old male with spontaneous migration of bullet from arm to forearm. At the time of initial injury, bullet was left inside the arm as it was deep and patient had no complaints. Three months after injury, he started complaining of pain over forearm and tingling sensations in the forearm and hand over median nerve distribution. Radiographs showed bullet in the proximal forearm. The bullet was than precisely localized and removed under ultrasound guidance. This case report emphasizes the fact that spontaneous migration of bullet in extremities may occur and have the potential to cause neurovascular damage. Removal under ultrasound guidance is a viable option in such locations.Keywords Arm Á Bullet Á Spontaneous migration Sommario La migrazione spontanea di un proiettile trattenuto è rara. Presentiamo il caso di un paziente maschio, di 24 anni di età, con migrazione spontanea di una pallottola dal braccio all'avambraccio. Al momento iniziale, il proiettile era stato lasciato all'interno del braccio perchè in sede profonda in paziente con scarsa resistenza al dolore. Tre mesi dopo, questi ha iniziato a lamentare dolore al l'avambraccio e sensazioni di formicolio a braccio e mano, nelle aree innervate del nervo mediano. Le radiografie hanno mostrato il proiettile nell'avambraccio prossimale. Il proiettile veniva localizzato con più precisione e rimosso sotto guida ecografica. Questo caso sottolinea il fatto che la migrazione spontanea di un proiettile nelle estremità può verificarsi ed è potenzialmente causa di danni neurovascolari. In tale situazione la rimozione sotto guida ecografica è una valida opzione.

Wooden foreign bodies in soft tissue: detection at US.

Abstract: US can be used effectively to locate wooden foreign bodies as small as 2.5 mm in length. Given that many foreign bodies are radiographically undetectable, the accuracy and availability of US make it an excellent modality for evaluation of radiolucent foreign bodies.
