  Abstract 


Plexus-chorioideuscarcinomataor malignant plexus papillomas are very rare malignancy; only few cases have been described in the literature. A 2.5-year-old girl, known case of choroid plexus carcinoma, presented with complaints of weakness of right upper limb and lower limb, decreased activity, altered sensorium and vomiting. After re-evaluation, she underwent re-excision of tumor and chemotherapy started.

  Background Top


Choroid plexus carcinoma (CPC) is an uncommon intracranial neoplasm with virulent course and poor prognosis. Approximately 80% of CPCs arise in children which constitute about 15-20% of choroid plexus tumors (CPT).[1] The most common location is the lateral ventricles. Literature on CPCs is scant because of its rarity. Most are case reports or small case series.[2] We report a case of choroid plexus carcinoma in a 2.5-year-old child.


  Case Summary Top


A 2.5-year-old girl child without any comorbidities and normal developmental milestones presented with history of generalized tonic-clonic seizures, headache and vomiting of sudden onset. Past history and family history was not significant. A contrast-enhanced computed tomography (CT) scan of the brain showed a large well-defined heterogeneous lesion with cystic and hyperdense solid component with calcification, suggestive of supratentorial PNET/atypical teratoid-rhabdoid tumour/choroid plexus papilloma [Figure 1]. She underwent left posterior temporal craniotomy and near total excision of the tumor at another hospital.

The histopathology was suggestive of CPC. Immunohistochemistry for pan cytokeratin was strongly positive and glial fibrillary acidic protein (GFAP) was positive in occasional tumor cells. She did not receive any adjuvant therapy.

Three months later, she presented with vomiting, altered sensorium and weakness of right upper and lower limb. A CT scan showed a recurrence of the lesion. Magnetic resonance imaging of brain showed a large heterogeneous mass in the left fronto-temporo-parietal region with significant mass effect [Figure 2]. She underwent external ventricular drain placement, left temporo-parietal craniotomy and gross total excision of the tumor. Intraoperative findings revealed a greyish tumor which was soft, suckable and moderately vascular and arising from choroid plexus of lateral ventricle. Postoperative period was uneventful. Postoperative histopathology was suggestive of CPC WHO (World Health Organization) Grade III. Immunohistochemistry showed Cytokeratin, INI1 positivity and synaptophysin, GFAP and epithelial membrane antigen (EMA) were negative [Figure 3]. Postoperative CT scan revealed near total excision of tumor. She was started on chemotherapy with IEC (Ifosfamide, Etoposide. and Carboplatin) regimen.

  Discussion Top


CPT are rare central nervous system neoplasms accounting for 1-4% of all pediatric brain tumors.[3],[4] They are of neuroectodermal origin and most of the cases occur in infants, young children and rarely in adults. Choroid plexus tumors are categorized based on histological criteria as choroid plexus papilloma (CPP, WHO Grade I), choroid plexus carcinoma (CPC, WHO Grade III), and an intermediate entity termed atypical plexus papilloma (APP, WHO Grade II).[5]

Carcinoma of choroid plexus usually will have a virulent course and carry a poor prognosis. CPCs account for 15-20% of choroid plexus tumors and 80% of these are found in children. The most common site in children was lateral ventricles, as seen in the present case. CPCs are rare in adults and when diagnosed, most common site was fourth ventricle. Literature on CPCs is scant and only seven previous series were found in the past 30 years.

Clinically, CPCs cause hydrocephalus and increased intracranial pressure leading to convulsions, headache and rarely hemiplegia. A study by Bleggi-Torres et al. reported 15 cases of CPC, in which hydrocephalus, intracranial hypertension and convulsions were seen in 62.5%, 25%, 12.5% patients respectively. Neuroradiological features are nonspecific for CPC.

Most of the time, the diagnosis is established at histopathology. Sometimes, the distinction between choroid plexus papilloma and CPC is not obvious even with histopathology and in these cases immunohistochemistry becomes important in establishing the diagnosis, as happened in our case. CPP have histologic features that are very similar to those of the normal choroid plexus. The histologic criteria for malignant tumors of the choroid plexus, that is, CPCs were first developed by Lewis in the 1960s refined by Russell and Rubinstein two decades later, and most recently modified by the WHO. The established criteria are as follows: (1) obvious invasion of adjacent neural tissue with the infiltrating cells on a stromal base; (2) loss of regular papillary architecture; and (3) evidence of increased mitotic activity, nuclear atypia, and necrosis. CPCs typically stain positive for cytokeratins and display variable expression of vimentin, S100, transthyretin, and glial fibrillary acidic protein (GFAP). Positivity for S100 and transthyretin is typically less than that seen in CPP. CPCs stain positive for GFAP in approximately 20% of tumors.

Surgery is generally considered to be the most effective treatment and the most important prognostic factor.[6],[7] The extent of surgical resection remains the most important factor in determining long-term survival in patients with CPC, but patients treated only with surgery have had a very poor outcome, disease progresses rapidly, and patients often die within one year. The 5-year survival rate is 58% after complete tumor resection versus 20% after partial resection.[6] Adjuvant treatment of CPC may therefore be important not only for patients with partially resected CPC but also for patients with completely resected CPC.[5],[8]

In some small series, an objective response to radiotherapy was reported, showing that CPC is a radiosensitive tumor. Several case reports had described children with long-term survival who received radiotherapy. Larger analyses showed that radiotherapy improves the survival outcome of patients with CPC for incompletely and completely resected tumors. However, the late neurological sequelae of radiotherapy given to children under 3 years of age exclude this modality, leaving only chemotherapy as an adjuvant treatment for most patients with CPC.[5]

Although this tumor is still associated with a poor prognosis, there has been a slight but significant increase in survival throughout the past decades. Dohrmann and Collias reported a 9-month median survival time in a review of 16 children operated on for CPC.[9],[10] In 1992, Packer et al. reported 11 patients with CPC with a 45% event-free survival rate and a median progression-free time of 48 months.[7] Menon et al. reported median survival of 58 months for CPCs who underwent gross total excision with adjuvant therapy and of 36 months who had a subtotal resection with adjuvant therapy.[8]
