Ecchordosis physaliphora (EP) is a benign notochordal remnant most commonly encountered in the skull base. In opposition to typical cases of its invasive counterpart, that is, chordoma, EP does not show T1-enhancement. Now, we describe three patients with EP, discovered on delayed contrast-enhanced 3D FLAIR performed for endolymphatic hydrops imaging in suspected Menière's disease.

Nasopharyngeal cysts are rare benign entity, smaller in size and usually asymptomatic. They are mostly diagnosed incidentally on MRI. Larger cysts commonly presents with spasmodic and obstructive symptoms.

Article Synopsis
  • The study aimed to evaluate the clinical and imaging characteristics of ecchordosis physaliphora (EP) in 16 patients, along with a review of existing literature on the condition.* -
  • Among the patients, most were middle-aged, with headache and hearing loss being common symptoms; radiologically, EP was characterized by specific MRI features and no enhancement with gadolinium.* -
  • The findings highlight the importance of distinguishing EP from chordoma using imaging techniques, as many cases were discovered incidentally and a majority of patients showed good outcomes with conservative management.*

Article Synopsis
  • There are not many cases of tumours on the coccyx (the tailbone), so this study looked at a lot of them to learn more.
  • They found 103 cases over 15 years, mostly in older people, and most tumours were a type called chordoma.
  • The study emphasizes the importance of imaging tests to help understand and treat these rare coccyx tumours better.

Article Synopsis
  • This study examines 50 cases of distinct lesions derived from notochordal cells (NCDL), including various types of chordomas and benign tumors over the past 55 years in a tertiary hospital setting.
  • Conventional chordomas were found to be lobulated masses with specific imaging characteristics and a variety of growth patterns, while benign notochordal cell tumors (BNCT) were less aggressive, presenting as well-defined lesions without infiltration.
  • Follow-up strategies for BNCT involved radiological monitoring, showing no local recurrence or metastasis, while conventional chordoma cases faced higher risks with significant rates of local recurrence and metastasis, necessitating more aggressive treatments.
