The goal of this study was to evaluate the benefits of resident and fellow-facilitated radiology-pathology head and neck conferences. A total of seven resident-facilitated and six fellow-facilitated head and neck radiology-pathology cases were presented as part of the radiology department conference series. The radiology residents were surveyed regarding the perceived quality and effectiveness of the fellow-facilitated sessions. The number of publications yielded from all the cases presented was tracked. Overall, the residents assessed the quality of the fellow-facilitated conferences with an average score of 3...

BACKGROUND: When treatment of acute septic arthritis of the hip is delayed, severe sequelae can occur. This may take the form of coxa breva, vara, or valga. Pseudoarthrosis of the femoral neck is a rare complication with only a few studies to guide treatment. QUESTION/PURPOSES: In a small series of patients with pseudarthrosis of the femoral neck after acute septic arthritis, we wanted to determine (1) whether femoral neck union can be achieved using a variety of surgical approaches; (2) whether these patients satisfied criteria outlined by Hunka and Choi, defined as a stable hip, a flexion arc ≥ 70° and no fixed adduction or abduction contractures, fixed flexion deformity not more than 20°, pain relief, and restoration of activities of daily living after surgery; and (3) any treatment-related complications if observed...

Lymphoepithelial carcinoma (LEC) is a rare malignancy of the salivary gland arising from the parotid in 80% of cases. LEC is indistinguishable histologically from more common non-keratinising undifferentiated nasopharyngeal carcinoma (NPC). Up to 40% of patients with primary LEC present with a cervical metastasis and histological assessment of the primary lesion or nodal metastasis may be reported as NPC. The absence of a nasopharyngeal lesion on imaging and endoscopic assessment together with a parotid mass strengthens the case for a LEC...

The modern application of interventional radiology techniques is revolutionizing the treatment of the vascular malformations of the head and neck. In fact, the morbidity related with the surgical extirpation of the malformation might be drastically reduced with the use of an endovascular approach. The present report describes the case of a 11 years old male affected by a large intraosseous arteriovenous malformation of the mandible. The coil embolization of the main drainage vein caused the spontaneous regression of the lesion and avoided a mutilating surgery and severe psychological sequels...

In this paper, our main objective was to emphasize the competency of extended deltopectoral exposure, enforced with the supraspinatus and subscapularis detachment, to gain access to the entire head. The second important point in this paper was to underline the importance of the knowledge that is necessary for interpreting classic radiologic signs of posterior fracture-dislocation of the shoulder. A 47-year-old woman fell down directly onto her shoulder while she was skiing. She was diagnosed with posterior shoulder dislocation, associated with fracture of the head (head splitting) and humeral neck fracture, with the aid of plain radiographs and computed tomographic results...

Extraskeletal myxoid chondrosarcoma (ESMC) is an extremely rare variant of chondrosarcoma accounting for less than 10% cases. It affects mainly the soft tissues of the proximal end of long bones. Its incidence in the head and neck region is less than 5%. This case presented in the nasopharynx, an exceedingly unusual site for ESMC in a 60-year-old female with left-sided nasal obstruction and occasional epistaxis of one-year duration. Biopsy from the nasopharyngeal mass was suggestive of low-grade chondrosarcoma...

Poorly differentiated chordomas are rare musculoskeletal tumors. Case 1. A 42-year-old lady presented with quadriparesis of 2 months' duration. Radiologic imaging disclosed a soft tissue mass in her left prevertebral- and paravertebral cervical region. Case 2. A 4-year-old male child presented with neck pain and restricted head movements of 1-year duration. Radiologic imaging revealed a contrast enhancing, paraspinal soft tissue mass in his cervical region. Microscopic examination in both the cases revealed a cellular malignant tumor composed of moderate to markedly pleomorphic cells with interspersed mitotic figures, along with focal myxoid change and necrosis...

Distant metastasis in advanced breast cancer is not uncommon; however, spread to the paranasal sinuses is extremely rare. We present a case of a woman who presented to our ophthalmology colleagues with worsening unilateral proptosis secondary to a tumour mass within her ethmoid sinuses. Biopsy of the ethmoid tumour showed adenocarcinoma of unknown origin. Whole-body positron emission computed tomography demonstrated a breast primary lesion. The patient was treated with palliative chemotherapy, and the patient remains well at this point...

Non-Hodgkin's lymphoma (NHL) is a lymphatic system tumor originating from either B or T lymphocytes and shows a high malignant potential. In HIV-seropositive patients, NHL of head and neck is mainly found in Waldeyer's ring, oral mucosa, salivary glands, paranasal sinuses, and laryngeal tissue. Primary NHL rarely affects the bone. When the lesion affects the bones of the jaws, it is rare in the mandible when compared to the maxilla. In the reported cases, only 0.6% are found in the mandible. NHL of the mandible can be difficult to diagnose, and so the prime aim of the present case report is to establish appropriate diagnosis of one of such kinds...

RATIONALE: Head and Neck Solitary fibrous tumors (SFT) are very rare. They could be misdiagnosed as hemangiopericytomas (HPC). PATIENT CONCERNS: We report a 60 y o lady presenting with sinonasal mass, causing recurrent profuse bleeding. DIAGNOSES: Hemangioperocytomas versus SFT were among the differentials, according to Radiological studies. Upon Biopsy, the diagnosis of SFT has been adopted. INTERVENTIONS: Salvage pre-operative embolization resulted in bleeding control, bridging the patient to surgery...

BACKGROUND: As far as our literature searches showed us, morphological characteristics of cranium such as sutures, sutural bones and fontanelles had been examined from the skulls in the museums and dry specimens until now. As a modern method, 3D virtual remodeling of cranial bones by using MDCT-CTA can display in vivo morphological characteristics. In our study, we aimed to determine the presence and incidence of these morphological characteristics that can be clinically significant in our population, by using radiologic methods...
