Hydranencephaly is a rare entity with incidence of 1 in 10000 live births and is characterized by near total absence of cerebral cortex and basal ganglia which are replaced by cerebrospinal fluid. Various aetiologies of hydranencephaly have been suggested which include: Infarction, leukomalacia, diffuse hypoxic-ischemic brain necrosis, intrauterine infections leading to necrotizing vasculitis. Ultrasonography, Computed Tomography and Magnetic Resonance Imaging can easily detect and diagnose hydranencephaly. We present a case of 2-month-old term infant diagnosed with hydranencephaly on computed tomography.

Carcinomatous encephalitis is a rare entity, originally described by Madow and Alpers in 1951, which is characterized by tumoral spreading perivascular, without mass effect. Clinical manifestations such as hemiparesis, seizures, ataxia, speech difficulties, cerebrospinal fluid findings as well as computed tomography are nonspecific. This leads the physician to pursue more frequent diseases that could explain those manifestations - toxic, metabolic, and/or infectious encephalopathy. A magnetic resonance imaging (MRI) with gadolinium, the method of choice, presumes the diagnosis. Previous reports of this unusual form of metastatic disease have described patients with prior diagnosis of pulmonary adenocarcinoma. We present the case of carcinomatous encephalitis in a 76-years-old woman as the primary manifestation of occult pulmonary adenocarcinoma with its clinical, imaging, and anatomopathological findings.

Cerebellar Liponeurocytoma

ABSTRACTCerebellar liponeurocytoma is a rare oncological entity, and the knowledge about the treatment and outcome of these rare tumors is still evolving. Very few cases have been described in literature. We report a middle-aged male who presented with raised intracranial pressure features and gait ataxia. His imaging features revealed classical features of liponeurocytoma in cerebellar vermis, with abundant fat component evident in both computed tomography and magnetic resonance imaging. He underwent resection of the lesion and has been asymptomatic for 4 years. This report describes the classical radiological and immunohistochemical features of this rare entity with favorable outcome and reviews the existing literature.

Tomography Scan

Isolated sphenoid sinus mucocele (SSM) is a rare entity that can result in serious sequelae if diagnosis and treatment are inappropriately delayed. Typically, mucoceles are asymptomatic, and they are accidentally identified after computed tomography scan or magnetic resonance imaging of the maxillofacial area performed for other pathologic issues. We report a case of isolated SSM that only presented with headache for over a year, and also review the literature regarding surgical management of such entity.

Cerebellopontine angle extraaxial glioblastoma (GBM) is extremely rare at any age but especially in children. We reported a case of 14-year-old girl, who presented with nausea, vomiting and ataxia. She was evaluated with computed tomography (CT) and magnetic resonance imaging (MRI). Imaging demonstrated irregular ring enhancing right CP angle mass. The atypical findings of irregular ring enhancement, CP angle location and presentation in childhood, combine to make the prospective diagnosis of GBM a difficult one. This combination of findings has been reported very rarely.

Retinoblastoma is the most common primary intraocular tumor in pediatric patients. The incidence accounts for 1 in 20,000 live births. With the improvement of treatment alternatives the survival rate of these patients has improved in recent years, with up to 95% survival in the US. The use of multimodal investigations including ultrasonography, computed tomography, magnetic resonance imaging, and wide-field fundus photography with intravenous fluorescein angiography is crucial to identify retinoblastoma in pediatric patients.

Cardiac Lesions

Rosai-Dorfman disease (RDD) is a rare entity that usually involves the lymph nodes but extranodal involvements have been seen in numerous cases, although RDD with cardiovascular involvement is extremely rare. We describe a case of a young male who presented with intermittent palpitations and was found to have a left atrium mass. Our case not only emphasizes the rarity of the above lesion but also highlights the importance of modern-day imaging like computed tomography, Cardiac Magnetic Resonance Imaging (CMRI), and PET scan in characterizing such nonspecific lesions and directing appropriate line of treatment. RDD should be considered as one of the differentials even for isolated cardiac lesions.
