Colloid cysts are benign, thin walled spherical neoplasms, composed of a collagenous capsule, underlying epithelium that arises from brain’s epidermal embryonic remnants and a viscous centre. They are shown to approximate 0.5% of all intracranial tumours with no recorded evidence of the petrous temporal bone involvement. Colloid cyst of the petrous temporal bone often presents with clinical symptoms of headache, hearing loss, facial palsy and imbalance/vertigo. Which is diagnosed on radiological and histological findings. Histologically, they are lined by ciliated cuboidal to pseudo stratified columnar epithelium resting on an eosinophilic basement membrane. Imaging Techniques are helpful in early diagnosis and preventing further complications. Here we will be discussing about a 24-year-old female, a known case of petrous apex osseous haemangioma presenting with unstable gait and tingling sensation on one side of face leading to an incidental finding of a colloid cyst on petrous temporal bone through histological examination.

Petrous Temporal Bone

AbstractSporadic case reports and the few published series of expanding lesions of the deep petrous temporal bone propose a variety of surgical approaches to ensure excision. All such surgery represents a compromise between exposure adequate for total removal and avoidance of further neurological deficit. Unfortunately pathology in the petrous apex evolves relatively silently and diagnosis is delayed. In many cases total excision is impossible. We present a series of patients presenting with advanced tumours of the deep petrous temporal bone in order to illustrate the spectrum of disease encountered, the limited role of surgery and the natural history of irresectable pathology in this remote and inaccessible area.

ABSTRACT A retrospective review of colloid cysts diagnosed from 1974 to 1986 emphasizes the presenting symptoms of these lesions, their surgical management, and the contribution of modern imaging techniques to their diagnosis and therapy. In this 12-year period, 84 patients (45 men and 39 women) had a colloid cyst diagnosed. The patients' mean age was 46 years (range, 7-82 years). Surgery was performed in 55 patients, 7 of whom had undergone prior surgery elsewhere. The surgical approaches used were transfrontal-transventricular, transcallosal, computer-assisted stereotactic aspiration and resection by stereotactic craniotomy, and shunting of cerebrospinal fluid without removal of the lesion. There was no operative mortality, but complications occurred in 15 patients (27%). Preoperative imaging showed hydrocephalus in 93% of the patients: severe in 43%, moderate in 36%, and mild in 14%. In the surgically treated group, the most common presenting symptoms were headache, change in mental status, ataxia, nausea and vomiting, visual disturbance, emotional lability/inappropriate affect, depersonalization, and hypersomnolence. Twenty-four patients for whom surgery was not recommended are being followed up closely. Most of these patients had normal ventricles. The symptoms in this group included headache, anxiety/nervousness, ataxia, memory impairment, visual disturbance, and seizures. Five autopsy cases of patients with colloid cysts were available during this period and were reviewed. Direct removal of colloid cysts can be accomplished with low morbidity and mortality, avoiding the frequent revisions and complications related to shunt procedures. There is a subgroup of colloid cysts that can be operated upon electively or followed up closely with serial imaging studies.

Diffusion Kurtosis

Background and purposes Minimal hepatic encephalopathy (MHE) has no recognizable clinical symptoms, but patients have cognitive and psychomotor deficits. Hyperammonemia along with neuroinflammation lead to microstructural changes in cerebral parenchyma. Changes at conventional imaging are detected usually at the overt clinical stage, but microstructural alterations by advanced magnetic resonance imaging techniques can be detected at an early stage. Materials and methods Whole brain diffusion kurtosis imaging (DKI) data acquired at 3T was analyzed to investigate microstructural parenchymal changes in 15 patients with MHE and compared with 15 age- and sex-matched controls. DKI parametric maps, namely kurtosis fractional anisotropy (kFA), mean kurtosis (MK), axial kurtosis (AK) and radial kurtosis (RK), were evaluated at 64 white matter (WM) and gray matter (GM) regions of interest (ROIs) in the whole brain and correlated with the psychometric hepatic encephalopathy score (PHES). Results The MHE group showed a decrease in kFA and AK across the whole brain, whereas MK and RK decreased in WM ROIs but increased in several cortical and deep GM ROIs. These alterations were consistent with brain regions involved in cognitive function. Significant moderate to strong correlations (–0.52 to –0.66; 0.56) between RK, MK and kFA kurtosis metrics and PHES were observed. Conclusion DKI parameters show extensive microstructural brain abnormalities in MHE with minor correlation between the severity of tissue damage and psychometric scores.

The clinical symptoms of chiasmal-cellular formations are similar, which significantly complicates its differential diagnostics. The differential diagnostics of chiasmal-cellular cysts, which include colloid cysts, arachnoid cysts, Rathke’s pouch cysts, epidermoid and dermoid cysts, is especially difficult. Nevertheless, an accurate preoperative differential diagnostics of chiasmal-cellular cysts is an important stage of preparation for surgical treatment, which allows determining the surgical tactics in advance, because each group of chiasmal-cellular cysts has its own features of surgical treatment, which significantly reduce the number of complications and minimize the number of recurrences. This study intended to improve the efficiency of diagnostics of the chiasmal-cellular cysts by determining the criteria for its differential diagnostics. 94 patients with chiasmal-cellular cysts and pituitary adenomas were examined and treated in the period of 2009 and 2018 for this purpose. As the most frequent pathology of the chiasmal-cellular area, pituitary adenomas were selected as a comparison group due to the fact that it is often necessary to differentiate chiasmal-cellular cysts with this pathology. Patients were divided into 5 groups according to the nosology of the disease. Clinical picture, laboratory analysis and MRI data were studied in each group. Statistical analysis and comparison of the data obtained among all groups were performed, and it allowed to determine the distinctive diagnostic features incidental to each group. It is possible to make an accurate preoperative diagnosis based on the specific features of differential diagnostics.

BACKGROUND : Colloid cysts are one of the rare brain tumours and are mostly located in the anterosuperior portion of the third ventricle, between the fornix and surround of Foramen of Monroe. OBJECTIVES: Ÿ 1.To review the demographic information & analyse clinical manifestations of patients presenting with colloid cyst of third ventricle. Ÿ 2.To analyze the advantages and disadvantages of various surgical approaches Ÿ 3.To assess the surgical outcome in colloid cyst patients operated by any method. MATERIALS AND METHODS: A retrospective study was performed on 16 patients who presented with a colloid cyst and underwent surgery at the Department of Neurosurgery, King George Hospital, Andhra Medical College between 2013-2018. They were evaluated based on clinical ndings and imaging features, surgical approaches used for resection and their outcomes. RESULTS: Sixteen cases of colloid cyst of the third ventricle were operated upon between 2013-2018. There were seven male and nine female patients with their ages varying between 9 and 62 years old. Nine patients were operated on by using a transcortical trans-ventricular approach, four using the anterior trans-callosal approach and, three patients by using an endoscopic approach. In all patients, complete excision of the lesions was achieved. CONCLUSION: Colloid cysts, though benign, present surgical challenges because of its deep midline location. Complete excision of the colloid cyst carries an excellent prognosis. Surgery is a safe and effective treatment option for this benign lesion.

The Common

Rhabdomyosarcoma (RMS) of the biliary tract is a rare tumor that commonly arises from the common bile duct. The most common clinical symptoms are obstructive jaundice and abdominal pain. Although diagnosis is often difficult and is frequently made during surgery, diagnostic imaging techniques including ultrasound, computerized tomography scan, and magnetic resonance cholangiopancreatography remain useful in the diagnosis and evaluation of biliary tree anatomy. In order to improve prognosis, different rhabdomyosarcoma study groups have adopted multidisciplinary treatment approach. Herein we describe a case of three-year-old child with Embryonal rhabdomyosarcoma originating in the common bile duct who was treated with surgery, chemotherapy according to European soft tissue sarcoma group (EpSSG) protocol and adjuvant postoperative intensity modulated radiotherapy to surgical bed with 6 MV photons to a dose of 41, 4Gy in 23 fractions. One year and a half after the end of therapy, the patient is still disease free. Although Rhabdomyosarcoma of the biliary tract is a rare tumor, it should be considered in the differential diagnosis of patients who have obstructive jaundice and a cystic mass within the common bile duct. Once believed to be an incurable disease, the prognosis of patients with biliary rhabdomyosarcoma has improved with a multidisciplinary treatment approach.

Microsurgical Resection

Objectives: Cerebrospinal fluid shunting or microsurgical resection of the colloid cysts of the third ventricle have long been a standard treatment. The emergence of neuroendoscopy has lead to its application in various neurosurgical problems. Colloid cyst of the third ventricle is one such pathology where endoscopic treatment has been performed with great clinical success during the past decade. We now Although considered less efficacious than microsurgical excision endoscopic excision is less invasive and much simpler.Objectives: (1) to assess the extent of excision (2) to assess the morbid anatomy of the colloid cyst (3) to assess the risk of complications (4) to assess the functional outcome. Period: Eight years (Jul 2001-June 2009) Materials and Methods: Endoscopic resections of 15 colloid cysts of the third ventricle with obstruction of Foramina of Monroe in all cases. Results: Total removal was achieved in 10 (66.7%) cases. In 5 (33.3%) patients the colloid material was evacuated completely while the remnant of the capsule adherent to its origin was left behind. Two (13.3%) patients developed meningitis one week postoperatively and one diedsubsequently. Nine (60%) patients had excellent recovery as the symptoms were relieved during a period of 3 to 24 months. Five (33.3%) of the total patients required ventriculoperitoneal shunt for obstructivey drocephalus which developed with in 2 weeks after surgery. One out of the total number of patients deteriorated postoperatively on the existing neurological deficit. There has not been any recurrence until now with subtotal excision of the capsule. Conclusions: Keyhole surgery under endoscopic visual control offers an alternative, very effective minimally invasive approach for the excision of colloid cyst of the third ventricle and is likely to replace microsurgical resection as a standard procedure.

Persistent Headache

Headache is a common complaint during pregnancy and the puerperium. The differentiation between a benign headache and a headache that has an underlying more endangering cause, such as an intracranial tumor, can be difficult and often requires diagnostic procedures and brain imaging techniques. We report the case of an 18-year-old female patient who developed clinical symptoms—persistent headache followed by neurological deficit—in the last part of her pregnancy. A medulloblastoma (MB) was diagnosed and treated after delivery. We review 11 other cases of MB in pregnancy reported in the literature. The most common clinical manifestation at diagnosis was headache followed by neurological deficits. We discuss the association of brain tumor growth with physiological changes during pregnancy. We conclude that clinical features of intracranial tumors can be misinterpreted as pregnancy-related symptoms and should not be dismissed.
