Összefoglaló. A lateralis cysticus nyaki terimék két leggyakoribb oka a branchiogen cysta és a cysticus nyaki áttét. Az átfedő lokalizáció (a leggyakrabban a IIA nyaki régióban), a betegek életkora és az esetenként hirtelen kezdet alapján a két leggyakoribb ok differenciáldiagnózisa nagy kihívást jelenthet. Egy hirtelen fellépő fájdalmas, bal oldali nyaki duzzanattal, dysphagiával és lázzal jelentkező 72 éves férfi esetét ismertetjük. A nyak komputertomográfiás vizsgálata egy 6 cm legnagyobb átmérőjű, vastag falú, többrekeszes cysticus terimét igazolt. Infektív branchiogen cysta lehetőségére gondolva az elváltozást eltávolítottuk. A szövettan azonban p16-pozitív laphámrákot igazolt. A primer tumort végül az ipsilateralis tonsilla palatina állományában sikerült azonosítani. A beteg definitív radioterápiában részesült, és 18 hónappal a diagnózis után tumormentes. A nyaki cystákon, az infektív nyaki cystákon és a cysticus metastasisokon kívül a humán papillómavírussal összefüggő szájgarati laphámrákok infektív cysticus vagy necroticus metastasisait is figyelembe kell venni a lateralis cysticus nyaki terimék differenciáldiagnózisában. Orv Hetil. 2020; 162(15): 595–600. Summary. Branchial cleft cysts and cystic neck metastases are the two most common causes of cystic lateral neck masses. Based on the overlapping location (neck level IIA), patient age at onset and the occasionally sudden onset, their differential diagnosis is challenging. We present a 72-year-old male presenting with a suddenly emerging painful, left-sided neck swelling, dysphagia and fever. Computed tomography showed a 6 cm thick-walled multicystic mass. With the suspected diagnosis of an infected branchial cleft cyst, the lesion was removed. Histology confirmed p16 positive squamous cell carcinoma. Primary tumor was identified in the ipsilateral palatine tonsil. Definive radiotherapy was performed and the patient is free of disease at the 18-month follow-up. Beyond pure and infected branchial cleft cysts and pure cystic metastases, infected cystic or necrotic metastasis of human papillomavirus associated oropharyngeal squamous cell carcinoma should be included in the differential diagnosis of cystic lateral neck lesions.

Branchial Anomalies

Branchial cleft anomalies are an important differential diagnosis in congenital neck masses in infants. The third and fourth branchial anomalies are rare branchial cleft anomalies, which are hard to differentiate. We report here an uncommon case of the fourth branchial anomaly that was presented as an asymptomatic neck mass in a neonate.

Summary Purpose: Kikuchi disease (KD) is a benign and self-limited syndrome characterized by cervical lymphadenopathy. This study evaluated 18F-fluorodeoxyglucose positron emission tomography/ computed tomography (FDG PET/ CT) findings in patients with KD and analyzed their imaging features. Patients, material, methods: We evaluated the FDG PET/CT findings of 22 patients (14 men, 8 women) with KD, ranging in age from 9 to 73 years. All patients had been diagnosed based on the pathological findings of biopsy. We examined the locations, metabolic activity and size of hypermetabolic lymph nodes (LNs) on FDG PET/CT imaging with medical history including laboratory results. Results: Among the 22 patients, we identified 619 hypermetabolic LNs which had maximum standard uptake value (SUVmax) above 3.0. The 16 patients were studied with FDG PET/CT to identify the cause of fever, another 5 patients for their neck masses, and the remaining patient for his left inguinal mass. Hypermetabolic LNs were noted in neck (18 bilaterally, 2 right, 1 left) of 21 patients, axilla of 10, mediastinum of 9, abdomen of 17, pelvis of 6, and inguinal area of 3. The SUVmax of FDG uptake in affected LNs by patient base analysis were 6.2–29.4. Of the 619 hypermetabolic LNs identified, 440 LNs (71.1%) were less than 10 mm in their short axis determined by CT, and were occasionally aggregated. No patient showed solid organ hypermetabolic lesion in FDG PET/CT. Conclusion: Kikuchi disease could present multiple hypermetabolic LNs in body on FDG PET/CT. Based on the physical findings, consideration of the generalized distribution of the relatively small-sized hypermetabolic LNs, FDG PET/CT may be useful as a diagnostic tool in cases of Kikuchi disease.

Abstract Background The gold standard for verifying COVID-19 mostly depends on microbiological tests like real-time polymerase chain reaction (RT-PCR). However, the availability of RT-PCR kits can be known as a problem and false negative results may be encountered. Although CT scan is not a screening tool for the diagnosis of COVID-19 pneumonia, given the widespread acquisition of it in the pandemic state, familiarity with different CT findings and possible differential diagnosis is essential in this regard. Main text In this review, we introduced the typical and atypical CT features of COVID-19 pneumonia, and discussed the main differential diagnosis of COVID-19 pneumonia. Conclusions The imaging findings in this viral pneumonia showed a broad spectrum, and there are no pathognomonic imaging findings for COVID-19 pneumonia. Although CT scan is not a diagnostic and screening tool, familiarity with different imaging findings and their differential diagnosis can be helpful in a rapid and accurate decision-making.
