Predictors of dopamine agonist resistance in prolactinoma patients.

Background: Surgical resection of prolactinomas resistant to dopamine agonists is frequently incomplete due to fibrotic changes of the tumour under pharmacological therapy. In order to identify a subgroup of patients who may benefit from early surgery, we thought to investigate possible predictive factors of pharmacological resistance of prolactinomas to dopamine agonists.

Methods: We retrospectively analyzed a database of a Belgian tertiary reference center for patients with pituitary tumours from 2014 to 2016.

Bilateral lesions of the globus pallidus in a young woman.

We report a case of stroke due to cocaine abuse in a 30-year-old woman. The initial examinations pointing to this diagnosis were CT and MRI. Magnetic Resonance Imaging revealed bilateral globus pallidus infarction characterized by restricted Diffusion with low ADC values.

MRI in hypertrophic mono- and polyneuropathies.

Different conditions that may lead to enlarged nerves or nerve roots include hereditary motor and sensory neuropathy (HMSN), neurofibromatosis (NF) type 1, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and intraneural perineurioma. Differential diagnosis of hypertrophic mono- and polyradiculopathies remains challenging but is important because of different treatments and prognosis. Magnetic resonance imaging (MRI) can identify the hypertrophic nerve segments and guide a fascicular biopsy.

[Frontal syndrome post cerebral malaria. Case report].

Cerebral malaria is one of the most serious complications of Plasmodium falciparum infection, this protozoa of the Plasmodium family is the only known to induce cerebral malaria. This case is about a frontal lobe syndrome post cerebral malaria in a young man living in an endemic malaria area. This complication is rare and most common during childhood.
