Hepatocellular carcinoma (HCC) rarely metastasizes to the extra ocular muscles (EOMs). We present a case of bilateral metastasis of HCC to the EOMs and focus on the magnetic resonance imaging (MRI) features. Orbital MRI revealed nodular enlargement of bilateral multiple EOMs, with isointensity on T1-weighted images and heterogeneous, intermediate-to-high signal intensity on T2-weighted images, ...

Gastric cancer with double metastasis to the orbit and duodenum is extremely rare. We report the case of a patient with gastric adenocarcinoma who presented with synchronous orbital and duodenal metastases at the time of initial diagnosis. A 60-year-old man presented with a 1-month history of visual disorder and pain in his right eye. He underwent ophthalmological examinations. The biopsy resul...

PURPOSE Malignant sinonasal tumors are clinically challenging due to their proximity to vital structures and their diverse histogenesis and biological behavior. To date, no animal models accurately reflect the clinical behavior of these malignancies. We developed an orthotopic murine model of sinonasal malignancy that reproduces the intracranial extension, bony destruction, and spread along neu...

REESE (1951) and other authors hold that, except when an orbital tumour is palpable, no surgery should be attempted unless a deep orbital tumour affects the function of the eye or the optic nerve. Reese recalled no case in which the orbit had been explored with benefit, merely because of an unexplained unilateral proptosis. Among my series of 130 cases of unilateral proptosis, mostly caused by ...

A huge retroperitoneal tumor with a right orbital mass was detected and proved to be an extragonadal nonseminomatous germ cell tumor on biopsy. BEP chemotherapy caused some regression in orbital mass however no change in retroperitoneal tumor size as well as serum tumor marker levels occurred. Herein, we present a rarely seen entity of extragonadal retroperitoneal nonseminomatous germ cell tumo...

Nasopharyngeal carcinoma (NPC) is one of the commonest head and neck malignancies in South East Asia. The tumor arises from epithelial layer nasopharynx, found most frequently at Fossa Rosenmuller (FOR). NPC can spread to its adjacent structures cause distant metastasis. However, occurrence dura metastasis uncommon despite being closely located. Consequently, a lesion may be misdiagnosed as men...

Introduction. A range of traumatic, vascular, inflammatory, infectious, and neoplastic processes can affect the orbit and its structures. In the area of otolaryngology, the rhino-orbital-cerebral involvement of invasive fungal rhinosinusitis can affect the orbit, which may look like initially a rhinosinusitis or even mimic malignancy. Case Presentation. Female patient, 32 years old, with headac...

Orbital metastasis of systemic cancer is rare and has fascinated the attention of both oncologist and ophthalmologists ever since the first description of a case report by Horner in 1864. The clinical characteristics of tumors metastatic to the orbit are related to primary tumor biology, and vary substantially among various primary types. The common known primary sites include breast, lung, pro...

PURPOSE Olfactory neuroblastoma (ONB) is a rare neuroectodermal malignant neoplasm that originates from the olfactory sensory epithelium. In reported cases involving the orbit, the primary neoplasms could invade the orbits through bone destruction or cranio-orbital communication anatomical structure. The present study reports a rare case of orbital metastatic tumor arising from an intracranial ...
