Introduction:
Hydatid disease of bone is very rare accounting for 0.5% - 3% of all localisations.
Case Report:
We report the case of a woman of 30 years who presented with posterior chest pain. The chest radiograph showed an extra-pulmonary mass associated with a lytic rib lesion. Thoracic ultrasound revealed a multiloculated soft tissue and fluid mass. CT scan showed a fluid filled costo-vertebral cyst. MRI identified extension into the spinal canal. Pathological examination of the surgically resected material confirmed the diagnosis.
Conclusions:
This observation emphasises the role of MRI in assessing the extent of hydatid cysts of the posterior chest wall and in particular invasion of the spinal canal.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
