Photon-counting CT uses a novel x-ray detection mechanism that confers many advantages over that used in traditional energy integrating CT. As photon-counting CT becomes more available, it is important to thoroughly understand its benefits and highest yield areas for improvements in diagnosis of various diseases. Based on our early experience, we have identified several areas of neurovascular imaging in which photon-counting CT shows promise. Here, we describe the benefits in diagnosing arterial and venous diseases in the head, neck, and spine...

INTRODUCTION: Scapular anatomical neck fractures are among the most infrequent shoulder girdle fractures. Only seven radiologically confirmed cases of scapular anatomical neck fractures have been documented in the literature to date, of which only one case underwent delayed surgery. CASE PRESENTATION: A 34-year-old male Persian patient with morbid obesity was diagnosed with a scapula anatomical neck fracture after a motor vehicle collision. The radiographic assessment of the patient indicated an increase in the scapular glenopolar angle (73...

Paragangliomas (PGLs) are rare neuroendocrine tumors. Sometimes, these tumors secrete excessive catecholamines, which results in the manifestations of various signs and symptoms, usually with a triad of hypertension, tachycardia, and headache. We report the case of a 42-year-old woman presenting with uncontrolled hypertension, right facial palsy, vomiting, and disturbed gait. Diagnosis for PGL was confirmed on postoperative histological examination of the excised mass and correlated with preoperative clinical and radiological findings...

BACKGROUND: Tumour hypoxia is a recognised cause of radiotherapy treatment resistance in head and neck squamous cell carcinoma (HNSCC). Current positron emission tomography-based hypoxia imaging techniques are not routinely available in many centres. We investigated if an alternative technique called oxygen-enhanced magnetic resonance imaging (OE-MRI) could be performed in HNSCC. METHODS: A volumetric OE-MRI protocol for dynamic T1 relaxation time mapping was implemented on 1...

OBJECTIVE: Metastasis suppressor protein 1 (MTSS1) is a prognostic tumour marker in different malignant epithelial tumour entities and previously mainly the MTSS1 expression was analysed. This study evaluated the best analysis method as a prognosis and aggressiveness tumour marker in head and neck squamous cell carcinoma (HNSCC). STUDY DESIGN: MTSS1 expression, MTSS1 intensity, interpretation MTSS1 score and MTSS1 edging score were analysed in formalin-fixed paraffin-embedded tissue slices of 60 patients with proven HNSCC and correlated with clinical and pathological outcome parameters...

PURPOSE: Toxicities from head and neck (H&N) radiotherapy (RT) may affect patient quality of life and can be dose-limiting. Proteins from the transforming growth factor beta (TGF-β) family are key players in the fibrotic response. While TGF-β1 is known to be pro-fibrotic, TGF-β3 has mainly been considered anti-fibrotic. Moreover, TGF-β3 has been shown to act protective against acute toxicities after radio- and chemotherapy. In the present study, we investigated the effect of TGF-β3 treatment during fractionated H&N RT in a mouse model...

We describe temporal bone high resolution computed tomography (HRCT) findings in a case of bilateral mixed fenestral and retrofenestral otosclerosis with onset in the postpartum period. This condition should be considered in women complaining of postpartum hearing loss and temporal bone HRCT is a fundamental tool leading to the diagnosis.

A Gentleman in his 40s presented to us with left-sided hemifacial pain and nasal discharge for the last three days. He has been on immunosuppressive therapy for Wegener's Granulomatosis for over five years. Crusting was seen in the Left middle meatus upon clinical examination. Based on the post-covid status, steroid therapy, KOH mount, and radiologic imaging, a provisional diagnosis of Sinonasal mucormycosis was considered. He was posted for emergency debridement followed by Liposomal Amphotericin B and steroid therapy...

The objective of this study was to review the clinical, radiologic, and histologic aspects of cases of dentigerous cysts metamorphosing into different entities along with comments on the molecular factors involved in the process. A series comprising 8 cases of dentigerous cysts was performed retrospectively along with a comprehensive literature review. Two cases of dentigerous cyst converting into mucous metaplasia were included, out of which one case was transformed into ameloblastoma after a year. The other two cases were reported as acanthomatous and unicystic ameloblastoma, whereas four transitioned to AOT...

Total laryngectomy is the primary treatment for locally advanced laryngeal carcinomas. However, routine thyroid removal (total or hemithyroidectomy) during this procedure is controversial, as the incidence of thyroid gland involvement varies and may lead to lifelong thyroid supplementation, increasing postoperative morbidity. The lack of a consensus on managing the thyroid gland in laryngeal carcinoma cases necessitates improved evaluation techniques, with radiology playing a crucial role in this aspect. Understanding the correlation between radiological factors and histopathological involvement of the thyroid gland can aid in formulating appropriate management strategies during total laryngectomy...

We aimed to compare the demography, clinical profile, histopathology, fungal culture, radiology, surgery performed, medical therapy and outcomes of patients with acute invasive fungal sinusitis seen during the first and second waves of the COVID-19 pandemic by retrospectively reviewing their case records. Of 238 patients, 43(18.1%) presented during the first wave and 195(81.9%) during the second wave. Patients seen during the first wave were older (p = 0.04) and more likely to have visual impairment (p = 0...

Thyroglossal cyst (TGC) is the most common congenital anomaly of the thyroid gland and is found in approximately 7% of general population. It represents cystic degeneration of a remnant of the thyroglossal duct that failed to involute during gestation. Malignancy occurring in TGC is rare entity, accounting only for 1% of all thyroglossal cysts. We are presenting such a rare case of papillary thyroid carcinoma arising in a thyroglossal cyst. 30-year-old female presented with a painless, gradually progressive swelling below the chin extending to left side...

Cysts in the parotid region are more common in the gland than in the duct. Isolated cyst of parotid duct is a rare presentation. The treatment for most of the cystic lesions of the parotid or the parotid duct is the excision of the cyst with superficial parotidectomy. However, these lesions can be approached intra-orally for marsupialization achieving the same surgical results with less morbidity. This paper presents a rare case of parotid duct cyst which was managed by intraoral drainage and marsupialization...

The second wave of COVID pandemic was associated with an outbreak of Mucormycosis. The mortality rate of Mucormycosis reaches 50-80% in cases with orbital and intracranial extension (Fadda in Acta Otorhinolaryngol Ital 41:43-50, 2021). In this outbreak we found that few of these patients had bacterial invasive sinusitis mimicking fungal sinusitis. Amphotericin the only effective drug against Mucormycosis is highly toxic and expensive and not indicated in bacterial sinusitis. Our aim was to  determine the exact etiologic agent, predisposing factors and outcome of treatment of COVID associated invasive sinusitis presenting with orbital complications...

Non-ossifying fibroma (NOF) of jaw bones are rare. While NOF is the most common benign bone tumor of long bones with pathognomonic radiological features and bear a tendency for self-regression, gnathic NOF appears to be comparatively larger in size and behave more aggressively. A 16 years old female patient reported with painless swelling of the right side of the face of 4 months duration.

Acute invasive fungal sinusitis (AIFS) is a rapidly progressive infection predominantly seen in immunocompromised patients. There is an increasing incidence of AIFS post COVID-19 infection. Yet, there is sparse literature regarding spectrum of cross-sectional imaging findings (CT and MRI) in these patients, which is prudent for appropriate timely surgical intervention. This study aims to highlight spectrum of imaging findings in patients with post-COVID-19 AIFS integrating the clinical details from presentation to follow-up...
