Autoimmune pancreatitis presenting as a pancreatic head mass

The diagnosis of autoimmune pancreatitis (AIP) is often difficult as the main differential diagnosis is pancreatic head adenocarcinoma. Some clinical, radiological, serological and histological criteria help in guiding the diagnosis. The serum gamma-globulin IgG4 dosage is the most sensitive and specific marker. The shape of the ductal stenosis in AIP is characteristic. The treatment is based on corticosteroids. We report the case of a 53-year-old woman, presenting with pancreatic head mass mimicking an adenocarcinoma

JOUBERT SYNDROME: CLINICAL PRESENTATION AND NEUROIMAGING FINDINGS IN AN ADULT PATIENT - A CASE REPORT

<p>Joubert Syndrome (JS) is a rare genetic disorder that affects the cerebellum and the brain stem characterized by a distinctive midbrain-hindbrain malformation, leading to a variety of neurological symptoms. This case report aims to present the clinical features and neuroimaging findings of a 35 patient diagnosed with Joubert Syndrome. This case report contributes to the understanding of the diseases variability and progression in later stages of life. Increased awareness of JS in adults is crucial for timely diagnosis, appropriate management, and genetic counseling for affected individuals and their families. Further research is needed to unravel the underlying genetic mechanisms and explore potential therapeutic interventions for this complex neurodevelopmental disorder.</p><p> </p&gt

Lipid‐poor vertebral hemangioma mimicking a vertebral metastasis of cervical carcinoma

Key Clinical Message Vertebral hemangiomas are classified into typical and atypical forms. On imaging, atypical forms may look like malignant lesions. The confrontation of data from different imaging modalities (MRI; CT; scintigraphy) facilitates the diagnosis

Posterior reversible encephalopathy syndrome (PRES): Should more attention be paid to the atypical forms?

Posterior reversible encephalopathy syndrome (PRES) is an uncommon, but important, pathology affecting primarily the posterior cerebral circulation. Typical imaging features include vasogenic edema involving the bilateral occipital and parietal lobes. We report 4 cases of atypical PRES: The first one is a 59-year-old woman with a medical history of diabetes and hypertension who presented a consciousness disorder. MRI of this patient revealed signal abnormalities in the thalamus, the cerebellum, the brainstem and the corpus callosum with microbleeds and vascularization disorders. The second patient is a 41-year-old woman admitted for right hemiparesis and facial paralysis. Physical examination found a hypertension and the atypical imaging features on MRI were low ADC values with a pearl necklace appearance on ARM sequences. The third patient is a 32-year-old woman who undergone a surgery for an ectopic pregnancy and went in a coma for 8 days. Physical and biological parameters were normal. Diagnosis was delayed because of atypical signal abnormalities in caudal and lentiform nuclei that worsened on follow-up MRI, resulting in a dramatic evolution to bilateral cecity and psychosis. The last case is a 34-year-old woman with terminal renal failure hospitalized for spontaneously resolving tonic-clonic seizures. Biology showed high uremia and brain MRI revealed a gyriform enhancement at gadolinium injection with unilateral putamen lesion. The patient improved after blood purification. Knowledge of these atypical findings can help the radiologist make an accurate, timely diagnosis, and improve patient care

A rare case of Fahr disease revealed by an epileptic seizure

Fahr's disease is a rare neurodegenerative disorder, identified by bilateral and symmetrical intracerebral calcifications of mainly the basal ganglia. Patients often present extrapyramidal or neuropsychological symptoms. Seizure is one of the rarest manifestations that can reveal Fahr disease. We present the case of a 47-year-old male patient who had Fahr disease revealed by an inaugural tonic-clonic seizure
