RESUMO
Computed tomography scan findings are described in cerebral arterial gas embolism in two patients with right to left intracardiac shunts by accidental injection of air during intravenous therapy. Although imaging may not be necessary to diagnose the condition, the patient may be referred to CT scan as a case of stroke. Cerebral arterial gas embolism should be considered in the differential diagnosis of stroke, particularly in case of right-to-left shunts. CT findings described are classical and diagnostic of the condition.

Leiomyomas of the renal parenchyma and of the capsule are rare. These tumours are normally small asymptomatic and often detected incidentally. Large renal leiomyomas can present with pain or as an abdominal mass, but they are rare. The imaging features of these tumours have been poorly described in the literature. A radiological distinction from other renal neoplasms is often difficult to make owing to the similarity of imaging findings. We report two patients with renal leiomyomas who presented with pain and an abdominal mass. Both patients underwent nephrectomy and histological evaluation confirmed the diagnosis of leiomyoma.

Skeletal echinococcosis is a relatively rare entity and that of the rib is exceptional. Less than 50 cases of costal echinococcosis have been reported in the literature so far. Accurate pre-operative diagnosis aids in appropriate management and helps to eradicate the disease. This also prevents the dissemination of parasite and further complications. We report a case of echinococcosis of the rib with epidural extension in a young adult who presented with paraparesis and back pain. His laboratory investigations were within normal limits. Plain radiographs of the dorsal spine, CT scan of thorax and MRI of dorsal spine were performed. The imaging features were suggestive of echinococcosis involving the rib with epidural extension. The cyst was completely resected. Histopathology of the resected specimen confirmed the diagnosis of echinococcosis.
