Atypical cerebral MRI imaging findings in a patient with isolated neurosarcoidosis.

Sarcoidosis is a rare, chronic, granulomatous disease of unknown etiology and primarily effects the lymphatic and respiratory systems. The central nervous system (CNS) is unusually implicated in sarcoidosis patients. We describe a rare magnetic resonance imaging (MRI) findings in a case of isolated neurosarcoidosis.

Gastrointestinal stromal tumor of the small intestine with lung metastasis.

Gastrointestinal stromal tumours (GISTs) represent 1% of primary gastrointestinal cancers. These tumors most frequently metastasise to the liver and peritoneum and rarely to the lungs. We report the case of a 79-year-old woman with gastrointestinal stromal tumor of the small intestine and pulmonary metastases.

Acute pulmonary embolism mimicking COVID-19 pneumonia.

The case of 21-year-old man with an asthma history from childhood presenting severe respiratory distress associated with a right lower thoracic pain has been studied. The non-contrast Computed Tomography (CT)-chest scan showed a basal ground-glass opacity (GGO) of the right lung leading to suspicion of COVID-19 pneumonia. However, the molecular Reverse transcription polymerase chain reaction test and blood serology were negative while laboratory analyses revealed high levels of D-dimers (D-D).
