We report an observation of a macro- and microcystic lymphatic malformation located in the right upper limb. This was a 5-year-old girl with no previous pathological history, followed since the age of 11 months for a congenital subcutaneous, painless and soft swelling of the right upper limb. Ultrasound of the soft tissue and magnetic resonance imaging (MRI) allowed the diagnosis of macro- and microcystic lymphatic malformation of the right upper limb. There is little epidemiological data on cystic lymphatic malformations (CLM). Superficial MLKs are more numerous than deep MLKs; of the superficial MLKs, nearly 75% are located in the head and neck, with an estimated incidence of 1.2 to 2.8 per 1000 births, and in the axillary hollows in 20% of cases. They affect equally males and females and different ethnic backgrounds. Involvement of the upper limb and particularly the arm is very rare. MRI plays an important role in the diagnosis and assessment of the tumor's boundaries. Treatment can be difficult because of the location of the tumor and its extension into the surrounding tissue., Competing Interests: conflicts of interest: We wish to confirm that there are no known conflicts of interest associated with this publication and there has been no significant financial support for this work that could have influenced its outcome., (© 2022 The Authors.

Septo optic dysplasia plus is a rare disease seen in children. Its diagnosis is radiological, based on brain magnetic resonance imaging (MRI). We report the case of a child aged 2 years and 4 months, with no particular pathological history; who consulted for psychomotor retardation, strabismus and low vision behavior. An endocrine biological assessment exploring the hypothalomo-pituitary function was carried out, revealing no abnormality. The diagnosis of septo-optic dysplasia plus was retained on the brain MRI data, in front of the agenesis of the septum pellucidum and of the splenium of the corpus callosum, the hypoplasia of the optic pathways and of the pituitary stalk as well as in front of the agenesis of the posterior pituitary. It was associated with a closed schizencephaly. Septo-optic dysplasia is a rare congenital malformation. Our objective is to recall its semiology in imaging and to underline the importance of MRI to establish the diagnosis. Septo-optic dysplasia is a rare clinical entity typically involving midline brain abnormalities, optic nerve hypoplasia, and pituitary insufficiency. The association with cortical malformations such as schizencephaly and polymicrogyria denotes the term septo-optic dysplasia plus. Advances in imaging currently allow early diagnosis, which is essential for adequate management. Antenatal ultrasound may suspect dysplasia, and brain MRI confirms the diagnosis., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Lamiaa Chahidi El Ouazzani et al.)

Chiari III (CM III) is the rarest of the Chiari malformations, characterized by high cervical or occipital encephalocele and osseous defects, associated with herniation of the posterior cerebral fossa contents through the foramen magnum. We report the case of a female newborn, with a cervico-occipital mass, hypotonia and sharp osteotendinous reflexes in the lower limbs. An MRI was performed showing a low occipital encephalocele with caudal displacement of cerebellar tonsils. Because of its high contrast resolution, MRI is more useful than CT, preoperatively, to assess the content of the encephalocele. MRI can identify the position of the brain stem and spinal cord, so that they are preserved during the surgical procedure., (© 2021 The Authors.

Posterior Reversible Encephalopathy Syndrome (PRES) is a rare complication of Takayasu's Arteritis. We report the case of an 11-year-old girl who presented with a tonic-clonic seizure and loss of consciousness, without fever. Imaging revealed characteristic white matter edema of the occipital and parietal lobes, in keeping with PRES. Further imaging demonstrated right renal artery stenosis and wall thickening of the abdominal aorta. The combination of hypertension, the discrepancy of blood pressure recordings between upper limbs, and imaging abnormalities of the aorta and the left renal artery led to the diagnosis of PRES secondary to Takayasu's Arteritis. Treatment with oral corticosteroids, azathioprine, amlodipine, and propranolol resulted in the complete resolution of the patient's symptoms and imaging abnormalities., (© 2021 The Authors.

Superficial pseudoaneurysms of the palmar arch is a rare disorder and only a few cases have been described in the literature. In the majority of cases it develops after artery lesion following penetrating injury, previous surgery or arterial puncture. Diagnosis is based on strong clinical suspicion, especially in patients with pulsatile mass. We here report a case of false aneurysm of the superficial palmar arch following broken glass injury in a 3-year old child., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Fatima-Azzahra Samouh et al.)

Gastrointestinal (GI) bezoars are aggregates of undigested material found in the GI tract. Trichobezoar is the most common type of bezoars and consists of ingested hair, carpet fibers or fitted carpet fibers. They are mainly located in the gastric region, rare forms extend to the duodenum or small intestine and are described as Rapunzel syndrome. Typical CT imaging features play a diagnostic and prognostic role. We report the case of a 13-year-old girl hospitalized for occlusive syndrome due to trichobezoar., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright: Amina Mouffak et al.)

Gayet-Wernicke encephalopathy is a neuropsychiatric emergency due to thiamine deficiency (vitamin B1), secondary to several factors. We here report a case of Gayet-Wernicke encephalopathy in a 43-year-old woman who didn't consume alcoholic beverages, presenting with disorders of consciousness and diplopia with normal thiamine level. Classic triad of symptoms and Magnetic resonance imaging (MRI) played an important role, in particular, in the diagnosis of Gayet-Wernicke encephalopathy with normal thiamine levels in the absence of alcohol abuse., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright: Assia El Berhoumi et al.)

Sturge-Weber syndrome (SWS) or encephalofacial angiomatosis is a rare neurocutaneous and congenital ocular syndrome. It can cause two malformations: congenital facial capillary planar angioma and leptomeningal venous-capillary angioma (most often parieto-occipital homolateral angioma). Neuroimaging, in particular magnetic resonance imaging (MRI), plays an important role in the diagnosis, ideally before the occurrence of neuro-ocular complications. We report the case of a child in whom SWS was suspected based on facial angioma and pharmaco-resistant epilepsy., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêts., (Copyright: Meriem Doumiri et al.)

Solid pseudopapillary tumors (SPTs) constitute 0.2 to 2.7% of non-endocrine primary tumors of the pancreas and comprise the majority (70%) of pediatric pancreatic neoplasms. These tumors are of unclear pathogenesis, low malignancy and favorable prognosis. Surgical resection offers an excellent chance for longterm survival, even in the presence of distant metastasis. The objective of this study is to review our experience in the management of SPT in a 12 years old girl at the pediatric hospital of the University hospital of Casablanca, in Morocco and provide an update on current management in pediatric population., Competing Interests: The authors declare no competing interests., (© Ghita Berrada et al.)
