7-year-old boy with prodrome of right-sided and right face weakness, gait ataxia, and intermittent headaches. Head computed tomography demonstrated a tumor at the brainstem/posterior fossa, and then MRI confirmed a diffuse intrinsic pontine glioma (a typical brainstem glioma). Following initiation of dexamethasone (Decadron, steroid for vasogenic edema), the child has started experimental treatment with the medicine nimotuzumab to be followed with conventional radiotherapy.

1.5-year-old male suffered from eye swelling. His MRI revealed expansive lesion of left lateral orbital wall origin, with compression on the lateral rectus muscle. Later he was hospitalized due to fever and vomiting in left orbital lesion, suspecting a metastatic neuroblastoma. His eye examination revealed exophthalmus of the eye with exophoria and light dysfunction of the lateral rectus. His biopsies were indicative of stroma-poor neuroblastoma.

41-year-old male that in the past decade had suffered 2-3 times a year from bilateral knee pain which resolved spontaneously. Last year he had episodes of thumb pain that had lasted for several weeks and had affected grasp movements. The patient had responded to NSAID treatment for 2 weeks. MRI of the right knee showed Mild endoarticular effusion in the sub-quadriceps recess, chondropathy of the femoropatellar joint and lesion of the medial meniscus.

21-year-old female with an acute onset of a unilateral sixth cranial nerve deficit. Brain MRI showed at least a dozen white matter lesions, one of them contrast-enhancing. Sensory evoked potentials showed a bilateral increase in latency. Multiple sclerosis was diagnosed, and the patient was treated by corticosteroids, followed by improvement of symptoms. The first follow-up revealed no focal neurological signs with a history of a transitory unilateral lower limb hyposthenia. On the second visit, a horizonto-rotatory nystagmus and irregular paraesthesia in the right toes are documented.

47-year-old male has injured his right wrist while playing football 30 years ago. He always had some manageable pain while playing tennis. The pain increased during the last 12 months. The wrist CT scan that the expert recommended revealed diastasis between scaphoid and semilunar bone, palmar dislocation, dorsal intercalated segmental instability (DISI), marked radio-scaphoid arthritis and reactive sclerosis of the subchondral bone. This findings conformed the previous diagnosis of post traumatic osteoarthritis of radio-carpal joint brought upon by ligamentous injuries due to trauma.
