An unusual case of orbital tumor with high renin content and severe hypertension is described. The patient was a 15-year-old girl with juvenile hypertension (200-140 mmHg) associated with right exophthalmos and hypokalemia. The patient showed extremely high levels of plasma renin activity and plasma aldosterone concentration. No difference was present in plasma renin activity from either side o...

Dear Editor, Orbital metastasis infrequently occurs in breast cancer (1); however breast cancer is the most common cause of orbital metastasis (2-5), followed by lung, prostate, gastrointestinal tract, and skin (melanoma) cancers (6, 7). Definite diagnosis of an orbital lesion includes an orbital biopsy (either FNA or open biopsy). However, in patients with known metastatic cancer, CT scan or M...

Metastasis to the eye is rare, it can affect almost all ocular tissues. The association of metastasis to the optic nerve and lens dislocation in the same orbit is exceptional. We repport a 63 years old man presented with blindness due to a lens dislocation in the left eye. One month later, he presented a right hemiparesis. Brain magnetic resonance imaging (MRI) showing brain and intra orbital m...

Orbit has a complex anatomy with multiple structures embedded in it. Primary malignant tumors of the orbit are rare. Orbital neoplasms are usually multifaceted and require an interdisciplinary approach. They occur in adults over the age of 60 years. But benign orbital conditions can occur at young age [1]. After confirming the diagnosis of orbital tumors; various treatment methods performed are...

METASTATIC orbital tumours are relatively rare. This may be, as Giri (1939) has suggested, because of the difficulty encountered by blood-borne emboli in entering the right-angle bend from the internal carotid artery to the ophthalmic artery. The registry of Ophthalmic Pathology of the Armed Forces Institute of America included about 4,000 melanomata in 1958, but there were only 133 metastatic ...

Orbital apex metastasis from adenoid cystic carcinoma (ACC) is rare. We present a patient with known metastatic ACC presented with a rapidly declining vision with visual acuity oculus dexter (OD) equal to counting fingers at two feet. On imaging, she was found to have a right orbital apex tumor causing compressive optic neuropathy. She received the intensity modulated radiation therapy (IMRT). ...

Hepatocellular carcinoma rarely metastasizes to the orbit. We report a 45-year-old male, HBV+, HIV+, with a past history of a liver transplant for ELSD (end-stage liver disease) with hepatocellular carcinoma and recurrent HCC, who presented with proptosis and diplopia of the left eye. CT scans of the head revealed a large, irregular mass in the left orbit causing superior and lateral destructio...
