“…Although retropharyngeal abscess, osteomyelitis and malignant lymphoma are important differential diagnoses, we observed no inflammatory reaction on blood examination or destructive changes in the cervical spine in the present case, and no previous report has identified the cause of a fluid collection in the retropharyngeal space . Therefore, we excluded the aforementioned differential diagnoses.…”

We herein describe a 45-year-old man with posterior neck pain and severe dysphagia secondary to retropharyngeal calcific tendinitis. Brain stem infarction as a result of vertebral artery dissection was suspected, but head magnetic resonance imaging showed no acute ischemic lesion. Sagittal T2-weighted neck magnetic resonance imaging showed a retropharyngeal fluid collection from C2 to C8, and neck computed tomography showed calcification at the tendon of the longus colli muscle. Based on these characteristic imaging findings, retropharyngeal calcific tendinitis was diagnosed. Neurologists should remember that retropharyngeal calcific tendinitis can cause neck pain and severe dysphagia, and mimic brain stem infarction as a result of vertebral artery dissection.

“…The alar fascia has been shown to be an important landmark in the surgical approach of the retropharyngeal space (Ozlugedik et al 2005). The alar fascia is difficult to identify in radiological studies (Tomita et al 2016) but may occasionally be identified in CT or MRI of patients who develop oedema of the retropharyngeal space following radiotherapy (Mukherji & Castillo, 1998). It is also difficult to distinguish the retropharyngeal space and the danger space in adults (Stone & Figueroa, 2000;Warshafsky et al 2012), so most of the time, they are considered a single space (Guidera et al 2014).…”

Early stages of development of the alar fascia (human specimens at 6–12 weeks of development)

et al. 2019

In recent years, there has been much discussion concerning the cervical fasciae. The aim of this study is to confirm and to describe the development of the alar fascia as well as its relationship with nearby structures. Histological preparations of 25 human embryos (6-8 weeks of development) and 25 human fetuses (9-12 weeks of development) were studied bilaterally using a conventional optical microscope. Our study confirms the existence of the alar fascia and permits three stages to be established during its development. The initial stage (1st), corresponding to the 6th week of development (Carnegie stages 18-19), is characterized by the beginning of the alar fascia primordium in the retroesophageal space at the level of C7-T1. In the formation stage (2nd), corresponding to the 7th and 8th weeks of development (Carnegie stages 20-23), the alar fascia primordium grows upwards and reaches the level of C2-C3. In the maturation stage (3rd), beginning in the 9th week of development, the visceral, alar and prevertebral fasciae can be identified. The alar fascia divides the retrovisceral space (retropharyngeal and retroesophageal) into two spaces: one anterior (between the alar fascia and the visceral fascia and extending from C1 to T1, named retropharyngeal or retroesophageal space according to the level) and the other posterior (between the alar fascia and the prevertebral fascia, named danger space). We suggest that this latter space be named the retroalar space. This study suggests that alar fascia development is related to mechanical factors and that the alar fascia permits the sliding of the pharynx and the oesophagus during swallowing.

“…An explanation for the highly positive testing of the vagus nerve and carotid artery could result from the spatial proximity to the pharyngeal space. Also known as "Danger space," bacterial spread has been described in these regions [40]. It is worth noting that all tissues tested were positive for SARS-CoV-2 RNA.…”

Dying of VOC-202012/01 — multimodal investigations in a death case of the SARS-CoV-2 variant

et al. 2021

The current pandemic with Severe acute respiratory syndrome-coronavirus-2 has been taking on new dynamics since the emergence of new variants last fall, some of them spreading more rapidly. Many countries currently find themselves in a race to ramp up vaccination strategies that have been initiated and a possible third wave of the pandemic from new variants, such as the Variant of Concern-202012/01 from the B.1.1.7 lineage. Until today, many investigations in death cases of Coronavirus-disease-19 have been conducted, revealing pulmonary damage to be the predominant feature of the disease. Thereby, different degrees of macroscopic and microscopic lung damage have been reported, most of them resembling an Acute Respiratory Distress Syndrome. Far more, systemic complications of the disease such as pulmonary embolisms have been described. However, neither morphologic nor virologic findings of patients dying of the new variants have yet been reported. Here, we report on a comprehensive analysis of radiologic, morphologic, and virologic findings in a fatal case of this variant.
