The sagittal T2-weighted MRI scan shows expansion of the retropharyngeal
space with effusion (red arrow).
The differential diagnoses for primary retropharyngeal
processes include edema, cellulitis and abscess (Figures 3B and 3C).
She was investigated for septicaemia secondary to upper respiratory tract infection and possibly complicated by a parapharyngeal/ retropharyngeal
abscess in children: clinical presentation, utility of imaging, and current management.
Eight positive samples of the infected cattle had evidence of tuberculosis in the Liver, Lung and medial retropharyngeal
lymph nodes (Fig.
Wegener granulomatosis presenting as an infiltrative retropharyngeal
mass with syncope and hypoglossal paresis.
Although most of the time in adults the cause of a sore throat is viral in origin, and therefore antibiotics are of no use, in the case of confirmed strep throat, antibiotic treatment is important to prevent dangerous consequences, like rheumatic heart disease or retropharyngeal
Prognostic factors: Various potential prognostic factors including gender, age, stage, Histology, radiotherapy technology, concurrent chemotherapy, induction chemotherapy, lymph node, retropharyngeal
lymph nodes involved, lymph nodes extracapsular invasion, chemotherapy cycle, T/N-classification, induction chemotherapy regimens (TP; GP; FP), distant metastasis and relapse on predicting OS/LRFS/DMFS rates were evaluated in both univariate and multivariate analyses.
The most common metastatic site is the lung; the retropharyngeal
and caudal cervical lymph nodes are less frequently affected (CAPEN, 2002).
Especially, the occipital artery and branches that extended to the mandibular gland and to the medial retropharyngeal
lenf node of the ascending palatine artery were responsible for the vascularization of the cranial cervical ganglion.
Therefore an inflammatory response of the musculature will irritate the surrounding structures giving origin to patient symptomatology including decreased neck mobility, neck pain, and odynophagia, which can ultimately be confused with a diagnosis of retropharyngeal
abscess or meningitis (4).
On admission to tertiary care, an aetiological differential diagnosis for the pyrexia of unknown origin (PUO)  (Table 2) included retropharyngeal
abscess, Lemierre's syndrome, HIV seroconversion, and adult onset Still's disease (AOSD).
