UNUSUAL CLINICAL COURSE OF NEUROSARCOIDOSIS MANIFESTED WITH ACUTE HYDROCEPHALUS.

Approximately 5% to 15% of patients with systemic sarcoidosis develop neurological complications. However, the actual prevalence of subclinical disease may be higher. Symptoms are not specific, and may resemble those of other neurological diseases. Hydrocephalus occurs in 6% of patients with neurosarcoidosis. Acute hydrocephalus is extremely rare and when it occurs, it is usually difficult to diagnose, thus leading to possible complications. We present a patient who developed acute hydrocephalus due to neurosarcoidosis, for which he had to be operated on; soon after the operation, cranial infection developed that required definitive drainage system and ventriculoperitoneal shunt had to be implanted. In further complicated clinical course, after four years on corticosteroid therapy (corticosteroid dependent sarcoidosis), he had to be urgently operated on because of significant ventricular catheter adhesions, but several days after the operation he died in coma because of progressive brain edema not responding to treatment. As hydrocephalus due to neurosarcoidosis has high morbidity and mortality, early diagnosis and proper treatment are of utmost importance.

Spinal epidural granulocytic sarcoma in non-leukemic patient.

A previously healthy 24-year-old male presented with a 3-month history of progressive backache and weakness in both legs. Magnetic resonance imaging of the spine showed a large soft tissue mass infiltrating paraspinal musculature of lumbosacral area, sacral laminas, last lumbar and all sacral vertebra, protruding into the spinal canal, and with propagation into pelvis. Baseline laboratory data were normal. Decompressive laminectomy and tumor removal were performed resulting in neurological improvement. Histological examination identified granulocytic sarcoma (GS). Bone marrow biopsy showed normal findings. The patient underwent adjuvant chemotherapy and radiotherapy, resulting in the elimination of residual lesion, followed by autologous transplant. Immediate diagnosis and adequate systematic treatment are essential to achieve optimal results in patients with isolated GS. The patient is alive and free of the disease 14 months from the diagnosis.
