Plexus Papilloma

A 6-year-old, castrated male ferret (Mustela putorius furo) was presented with progressive neurological signs consisting of a right-sided head tilt and ataxia. Neurological examination revealed hemiparesis and absence of proprioception on the right side, consistent with central vestibular syndrome. Measurement of blood glucose excluded hypoglycemia due to insulinoma. Contrast-enhanced computed tomography revealed the presence of an intracranial mass, consistent with either granuloma or neoplasia. Palliative treatment with prednisolone yielded no improvement. At postmortem examination, a final diagnosis of a choroid plexus papilloma originating from the fourth ventricle was made. This is the first report of such a tumor in a ferret.

Abstract Primary angiosarcoma is extremely rare malignant tumor that has no typical symptoms and progress rapidly with poor prognosis. It is mesenchymal in origin and observed most frequently in the right atrium, cases in the pericardium is much more rare. Only few can detected in the early-stage allowing complete radical resection with a mean survival of 3 months to 1 year. There is few pericardial angiosarcoma reported among these years. The present study reports a case of a 44-year-old woman with primary pericardial angiosarcoma, who underwent a wide range of imaging methods, including transthoracic echocardiography, contrast-enhanced computed tomography (CT) and positron emission tomography-magnetic resonance imaging (PET-MRI). The patient recovered well after operation in two years and died due to the recrudescence and pulmonary metastases in April, 2020. We report the case for its rarity and revealing the early detection of primary pericardial angiosarcoma with imaging examinations is critical for prognosis. Finally a literature review is done.

Introduction: Renal trauma is a relevant cause of morbidity in children older than 1 year. Most patients are currently managed conservatively, even in case of high-grade traumas; nevertheless, harmful complications may occur even in hemodynamically stable patients. We present a case of grade IV blunt renal trauma complicated by post-traumatic pseudoaneurysm. Case description: A 10-year-old girl was referred to our institution for grade IV trauma of the right kidney. During observation she had persistent hematuria that caused anemia. A second contrast-enhanced computed tomography scan revealed a posttraumatic pseudoaneurysm that was successfully treated by angiographic embolization. Conclusions: Although extremely rare after blunt renal trauma, post-traumatic renal pseudoaneurysm may cause severe blood loss and anemia, and angioembolization is therefore indicated. This condition should be suspected and move physicians to investigate further.

Plexus Papilloma

Choroid plexus papilloma (CPP) is extremely rare in the brainstem. The authors report the case of a 10-year-old boy with a lesion in the pons that was misdiagnosed as a glioma preoperatively. The boy underwent partial resection of the lesion, which was diagnosed as a CPP based on histopathological findings. The authors review the MRI findings in this case and conclude that the presence of a well-defined boundary and no obvious cerebral edema are valuable features for distinguishing brainstem CPP from glioma. Although previous reports of parenchymal CPPs have described enhancement on contrast-enhanced T1-weighted MR images, the lesion in this case did not demonstrate significant enhancement. The authors note that the diagnosis of extraventricular CPP cannot be ruled out in a case of brainstem tumor without marked enhancement.

Plexus Papilloma

A 7-year-old spayed female English Cocker Spaniel was examined because of a 1-week history of lethargy, stumbling over objects and circling, and the presence of two tonic-clonic generalised seizures two days before presentation. The neurological signs suggested a lesion involving the right forebrain. Computed tomography revealed the presence of two intracranial masses, one located inside the right lateral ventricle and the other located in the right frontal lobe attached to the falx cerebri. Because of the poor prognosis, the owner refused to continue with the therapy and the dog was euthanised. On postmortem examination one mass was diagnosed histologically as a meningioma and the other as a papilloma of the choroid plexus. Information in the veterinary literature on multiple malignancies affecting the central nervous system is very limited. To the best of the authors’ knowledge, the association of meningioma and choroid plexus papilloma has never been reported either in the human or in the veterinary medical literature.

A 77-year-old man, who was on anticoagulation, presented with a painful lump on the right abdominal wall. Laboratory tests showed slight anaemia and elevated inflammatory markers. Abdominal plain computed tomography (CT) revealed a mass in the right rectus abdominis muscle. He was admitted with a diagnosis of primary rectus abdominis haematoma. However, on the next day, the diagnosis was corrected to primary rectus abdominis abscess, following contrast-enhanced CT of the abdomen. This case illustrates the importance of considering primary rectus abdominis abscess in patients with suspected primary rectus abdominis haematoma, and contrast should be used when performing CT.

Abstract The authors report the successful total removal of a rare intracranial tumor in the right lateral ventricle of a 15-year-old girl with epileptic seizures. Histopathological examination showed a benign tumor formed by mature cartilage and choroid plexus papilloma. From our review of the literature, a mixed tumor with these histological features has not been reported previously in this location. The diagnosis, surgical approach, etiology, and prognosis of this lesion are discussed.

Retroperitoneal paragangliomas are rare tumours arising from neural crest cells located near or in the autonomic nervous system; right from the skull bass to the pelvic floor. Often called the great masqueraders, their diagnosis and treatment is often difficult and fraught with danger, considering the close proximity of these tumours to important retroperitoneal organs. A 29-year-old woman presented to the outpatient department with complaints of paroxysms of headache, sweating and palpitations for one year. She was found to have elevated urinary metadrenalines (metanephrines) and a suprarenal mass on contrast-enhanced computed tomography of the abdomen, which demonstrated increased tracer activity on I-131 iodine-123 meta-iodobenzylguanidine scintigraphy. Adrenal pheochromocytoma was diagnosed and she underwent laparoscopic adrenalectomy after stabilisation of her blood pressure. Laparoscopy revealed a large suprarenal mass with dense adhesions to the inferior vena cava that was carefully separated from the vein and surrounding structures. The cut section revealed a heterogeneous mass encasing a normal adrenal gland and histopathology confirmed the same, confirming the final diagnosis of retroperitoneal paraganglioma.

✓ The authors report an unusual case of a 2-year-old boy with a 3-month history of episodic rightward anterolateral head tilt and large-amplitude positional anteroposterior head bobbing reminiscent of bobble—head doll syndrome. This child experienced a sudden onset of drop attacks and then, within several hours, deep coma. The causative lesion was a contrast-enhancing, partially cystic third ventricular mass, which ultimately obstructed the aqueduct, producing profound obstructive hydrocephalus. An emergency ventriculostomy and endoscopic fenestration of the septum pellucidum was performed. Four days later, the tumor was completely resected by a transcallosal—transforaminal approach. The lesion was freely mobile within the third ventricle and contained a large cyst within its posterior pole; following drainage of the cyst, the lesion was easily delivered through the foramen of Monro. The histopathological diagnosis was choroid plexus papilloma. The child's neurological deficits, head tilt, and head bobbing resolved immediately after operation. To the best of the authors' knowledge, this represents the first well-documented report of bobble—head doll syndrome and drop attacks secondary to a choroid plexus papilloma. The highly mobile nature of the cystic lesion presumably led to its intermittent impaction within the foramen of Monro and/or proximal aqueduct; this produced the intermittent head tilt and bobble-head symptoms and, ultimately, resulted in acute obstruction of the aqueduct, causing the child's precipitous neurological decline.

✓ An unusual case of a sacral, extradural choroid plexus papilloma involving the S1–3 level is described. This 50-year-old woman presented with a 4-month history of pain involving her right buttock, perineum, and leg. Contrast-enhanced magnetic resonance (MR) imaging of the spine revealed a well-defined, mildly enhancing sacral canal mass at the S1–3 level; its appearance was consistent with that of a benign tumor. Intraoperatively, the lesion was found to be extradural in location and was entwined among nerve roots in the sacral canal. Microscopic examination of the gross totally resected tumor revealed typical features of a choroid plexus papilloma. Despite performing a thorough neuroimaging workup (craniospinal contrast-enhanced MR imaging) for an intracranial or spinal primary mass, none was found. The choroid plexus appeared entirely normal; however, both a cavum septum pellucidum and a cavum vergae were noted. Extraneural choroid plexus papilloma, specifically intrasacral, extradural choroid plexus papilloma has not been previously reported. The present example is thought to have arisen either from ectopic choroid plexus tissue or perhaps by metaplasia from ependymal rests.

Introduction. Congenital respiratory stridor in children is the result of respiratory tract pathology located at various anatomical levels. There is an ongoing debate on whether every case of stridor requires diagnostic evaluation and which method is the most effective for determining the final diagnosis. Aim. The aim of the present study is to answer the question which procedure should be performed to diagnose the casuse of congenital stridor in children and why, and what the most common cause of the stridor is. Material and methods. A group of 110 children examined due to congenital respiratory stridor was analysed. The children’s general condition was assessed and imaging studies and lower respiratory tract endoscopy were performed under general anaesthesia. In some children cardiac ultrasound and contrast-enhanced radiographic examination of the oesophagus or contrast-enhanced computed tomography scan of the chest were performed. Results. Children aged 3 days to 11 years were analysed. The most common cause of stridor was congenital laryngeal hypotonia found in 50% of children and the second most common was abnormalities of the great arteries in 28% of children. Biphasic stridor, which may be a sign of multiple respiratory abnormalities, was diagnosed most frequently. It was only lower respiratory tract endoscopy performed under general anaesthesia that made it possible to make the right diagnosis. Conclusions. The most useful diagnostic method for congenital respiratory stridor is lower respiratory tract endoscopy under general anaesthesia, which is used to evaluate both the larynx and the trachea since defects may coexist at various respiratory levels. It is also for this reason that the type of stridor is not tantamount to the level at which the pathology is located in the respiratory tract. One needs to bear in mind that abnormalities of the great arteries may also be the cause of congenital respiratory stridor.
