Schwannomas of the parapharyngeal space are benign tumors that arise from the peripheral nerve sheaths and represent 0.09% of all head and neck tumors. Those originating from the vagus nerve are rarer. The diagnosis represents a challenge due to the different conditions encountered in the lateral neck. They usually present as asymptomatic lateral neck masses. An asymptomatic 42-year-old male patient sought medical advice. He underwent computed tomography scan and carotid angiography. The patient underwent complete resection and developed postoperative vocal cord paralysis. Dysphonia

<p class="abstract">Extracranial schwannomas in the head and neck region are rare neoplasms. The tumours often present as asymptomatic, slowly enlarging lateral neck masses. Though the computed tomogram criteria for differentiating vagal and sympathetic chain schwannoma is acceptable in most cases, but rarely the clinician may be misled in very large schwannoma of sympathetic chain where determination of the nerve of origin may be impossible until surgical exploration.</p>

Summary Introduction: Solid pseudopapillary tumor of the pancreas (SPTP) is a rare neoplasm of low malignant potential with uncertain behavior, diagnosed mainly in young women. Method: Our report comprises a series of cases of SPTP reviewed retrospectively, highlighting clinical, tomographic and immunohistochemical features, treatment performed and outcomes. Results: Thirteen patients were found to have pancreatic [solid] masses on computed tomography scan measuring a mean diameter of 8.8 cm. All patients underwent complete surgical excision. Immunohistochemistry confirmed diagnosis in all cases. Conclusion: SPTP occurs more frequently in young women. Diagnostic suspicion lies on the finding of a bulky, solid and cystic pancreatic mass. Imaging findings might provide diagnostic information before resection. Conservative approaches can be used in selected cases and survival rates are usually excellent following complete resection.

Metaphyseal Region

AbstractOsteochondromas are common benign tumors developing as an abnormal bony growth in the metaphyseal region. Being more of a developmental anomaly rather than a true neoplasm, they are usually found around the growth plates of long bones such as the knee, hip, and shoulder. These are typically managed conservatively if they are asymptomatic; however, they require excision in symptomatic patients. A 38-year-old woman presented with a huge swelling causing disfigurement measuring 16 × 16 cm on the left side of chest wall. Radiographs and computed tomography scan showed a bony outgrowth at costochondral junction of second rib which was in continuity with the periosteum. Excision via mediastinal sternotomy and left thoracotomy was done. Histopathological features corroborated with the radiological diagnosis of osteochondroma. Osteochondroma should be considered in the differential diagnosis of chest wall tumors. Rib is an extremely rare site of presentation. The cartilaginous cap becomes fully ossified and is lost in longstanding lesions. Huge tumors at such a location can cause irritation of adjacent viscera which can lead to pleural effusion or hemothorax; therefore, a cautious and logical approach to diagnosis is warranted for appropriate therapeutic management.

Lipomas are rare benign tumors in the larynx. We encountered a 70-year-old man with a large lipoma in the subglottic area. His chief symptom was a 3-month history of progressive dyspnea. Transnasal flexible endoscopy showed a large mass on the posterior wall of the subglottic region. A computed tomography scan revealed a lesion occupying 75% to 80% of the subglottic airway. In this article, we discuss the imaging changes, clinical evaluation, and treatment of this patient’s lipoma.

Metastatic parapharyngeal lymph nodes (LNs) from papillary thyroid carcinomas (PTC) are uncommon and can easily remain undetected. We describe a case that involves a 62-year-old woman treated for a PTC, who presented a rise in serum thyroglobulin (TG) levels. A computed tomography scan was performed, and revealed metastatic nodes in the left parapharyngeal space (PPS). A surgical resection of the nodes was performed with external cervical approach. A histological exam confirmed the diagnosis of a metastatic LN of a PTC. The aim of this report is to emphasize on the possibility of parapharyngeal metastatic nodes in PTC and to describe the diagnosis methods, treatment options, and impact on the prognosis.

Paratracheal Air Cyst

A tracheal diverticulum is a type of paratracheal air cyst and is usually an incidental finding after a computed tomography scan of the neck and thorax. With an incidence between 1% and 4% in adults, tracheal diverticula are rare entities that can be symptomatic in certain cases. We present a case of a COVID-19 positive patient who presented to our hospital and was diagnosed with multiple tracheal diverticula during his hospitalization.
