Lhermitte-Duclos disease is a rare disorder characterized by a slowly enlarging mass in the cerebellum. The exact nature of this lesion remains unclear, but it has been variously characterized as hypertrophy, hamartoma or benign neoplasm. Single-photon emission computed tomography (SPECT) with (123)I-iomazenil and (99m)Tc-ethyl cysteinate dimer (ECD) display central benzodiazepine receptors tha...

Colorectal masses can be non-neoplasm, benign neoplasm and malignant neoplasm. Diagnosis of colorectal mass done by biopsy or surgery then followed histopathological examination. The aim this study was to described the histopathology feature in Anatomic Pathology Laboratory Arifin Achmad Regional Hospital Riau Province January 2015 - December 2019. This found 304 cases consisted men (55,6%) wom...

A solid pseudopapillary tumor of the pancreas (SPT) is alternatively called a 'Frantz tumor.' It was first named after its discoverer in year 1959. This has been previously designated as papillary epithelial neoplasm, low-grade and neoplasm pancreas. rare pancreatic neoplasm. typically affects young people female predilection. Its histogenesis rather debatable. Acinar, endocrine, ductal...

Adenoid cystic carcinoma (AdCC) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). About 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). Three clinically obvious characteristics of AdCC include slow growth rate, perineural invasion and high incidence of distant metastasis (1). The most commonly-affected sites of...

Background: Choriocarcinoma is a rare highly malignant trophoblastic neoplasm. It can be preceded by any form of gestation including a complete or a partial mole, miscarriage and normal pregnancy. Simultaneous intraplacental choriocarcinoma involving both mother and infant is extremely rare. Hepatomegaly, anemia, elevated ßHCG is the diagnostic triad. Here we report a 6 weeks old Afghan girl in...

Neuroimaging, an important diagnostic tool frequently used in the evaluation of patients with epilepsy, has mainly the aim to identify structural abnormalities needing a treatment and to contribute to the definition of the aetiology. Brain magnetic resonance imaging (MRI) in epilepsy is more sensitive than computerized tomography (CT) scan for detecting abnormalities. Status epilepticus (SE) an...

Background: Tuberous sclerosis (TSC) is inherited as an autosomal dominant disease, characterized by skin lesion and tubers in vital organs, especially brain in three categories including subependymal nodules, cortical tubers and subependymal giant cell astrocytoma. Subependymal giant cell astrocytoma (SEGA) is an indolent neoplasm which usually arises at the cauda tha...

Advances in the fields of molecular and translational research, oncology, and surgery have emboldened the medical community to believe that intrinsic brain tumors may be treatable. Intraoperative imaging and brain mapping allow operations adjacent to eloquent cortex and more radical resection of tumors with increased confidence and safety. Despite these advances, the infiltrating edge of a neop...

Magnetic resonance imaging (MRI) provides detailed anatomic information of any part of the body. In this method a hybrid approach for classification of brain tissue in MRI based on Particle Swarm Optimization (PSO) and Support Vector Machine (SVM) wavelet based texture feature are extracted from normal and tumor region by using HAAR wavelet. These features are given as input to the SVM classifi...
