MRI Findings in a Young Boxer with Septic Physitis of the Humerus

ABSTRACT The MRI appearance of appendicular septic physitis has not been reported in small animals. MRI appearance of septic arthritis and osteomyelitis has been described in horses, and the use of MRI has been proposed as a diagnostic alternative to radiographs to allow for earlier diagnosis and treatment. MRI is also routinely used in human medicine for the diagnosis of osteomyelitis owing to increased accuracy of evaluation of the soft tissue involvement. In the case of a 5 mo old male boxer dog described here, radiographs were suggestive of the diagnosis of septic physitis, although an MRI was obtained to rule out neurologic etiologies of lameness based on history and physical exam findings. MRI identified a fluid pocket communicating with the physis. The diagnosis of septic physitis was then confirmed via ultrasound-guided fine-needle aspirate of the fluid pocket communicating with the physis that was seen on the MRI.

The Mean

Aim: To investigate the diagnosis and treatment methods of soft tissue involvement of hydatid cysts (HCs). Materials and Methods: Eleven patients who were diagnosed as having HC with muscular tissue (soft tissue) involvement between 2010 and 2016 were evaluated retrospectively. Seven patients had typical HC magnetic resonance imaging (MRI) and four patients had cysts with an unusual appearance. We evaluated how to diagnose the cysts using imaging methods, their characteristic radiologic images, and treatment alternatives against the disease. The patients were treated with antihelminthic chemotherapy preoperatively and postoperatively. Results: Of the 11 patients who underwent treatment, 7 were diagnosed using MRI and 4 were diagnosed with histopathologic examinations. The mean follow-up period was 16 (range, 6–24) months, and the mean age was 39.4 (range, 24–56) years. In seven patients, multivesicular appearance with specific MRI findings, T2-hypointense rim appearance, double-rim sign, membrane dissociation, and appearance of daughter cysts were identified as diagnostic criteria. Two patients underwent ultrasound assisted percutaneous aspiration–injection–reaspiration (PAIR) treatment. Seven patients underwent total pericystectomy, and two patients underwent subtotal pericystectomy with serum saline injection into the cyst. Two patients showed signs of mild anaphylaxis, one during the diagnosis and one during treatment. Conclusion: There may be difficulties in the diagnosis and treatment of HCs of the musculoskeletal system. It should be known that there are alternative methods in the treatment (cyst excision and PAIR treatment). Clinical, serologic, and radiologic findings should be used in the diagnosis. To avoid complications during the histopathologic diagnosis, MRI should be examined in detail. It is thought that atypical cysts can be diagnosed (double-layer appearance and peripheral rim sign) in addition to typical cysts (detached membrane and multivesicular appearance), and diagnosis and treatment can be planned without anaphylactic complications.

Ultrasound Guided

Foreign bodies (FBs) retained in the subcutaneous tissues are a common reason for medical consultation. In small animals, FBs usually consist of vegetal materials, especially grass awns. Failure to remove the FBs is likely to give rise to acute or late complications. The surgical removal of the FBs can be invasive, costly and technically challenging. Ultrasound has become a mainstay in the detection of FBs and it can be used to guide the extraction of the FBs with a minimally invasive technique. This study describes the detection and extraction of soft-tissue FBs in small animals. One hundred-sixty-two patients, presenting at two veterinary clinics with suspected FBs retained in the soft tissues of various body districts, were considered. Once an ultrasound diagnosis was established, the ultrasound-guided removal of the FB was performed. A high-frequency linear transducer, a skin disinfection, sedation or anaesthesia was used when needed and a scalpel and some Hartmann forceps were also used. One hundred-eighty-two FBs were successfully removed in all the patients. In six cases, the FB was identified during a second ultrasonographic examination, after recurrence of the fistula. No complications were reported after the procedure. The extraction of the FB was performed in an echographic suite in 138 cases and in a surgery room with surgical intervention in 24 cases. In the latter situation, the surgical minimally invasive dissection of tissues under ultrasound guidance was performed before the removal of the FB. In conclusion, the ultrasound-guided removal of the FBs retained in the superficial soft tissue can be considered a good alternative to surgery. However, failure to remove a FB does not preclude the removal by traditional surgery.
