Acute subdural hematoma: Outcome and outcome prediction

Patients with traumatic acute subdural hematoma were studied to determine the factors influencing outcome.Between January 1986 and August 1995, we collected 113 patients who underwent craniotomy for traumatic acute subdural hematoma. The relationship between initial clinical signs and the outcome 3 months after admission was studied retrospectively.Functional recovery was achieved in 38% of patients and the mortality was 60%. 91% of patients with a high Glasgow Coma Scale (GCS) score (9–15) and 23% of patients with a low GCS score (3–8) achieved functional recovery. All of 14 patients with a GCS score of 3 died. The mortality of patients with GCS scores of 4 and 5 was 95% to 75%, respectively. Patients over 61 years old had a mortality of 73% compared to 64% mortality for those aged 21–40 years. 97% of patients with bilateral unreactive pupil and 81% of patients with unilateral unreactive pupil died. The mortality rates of associated intracranial lesions were 91% in intracerebral hematoma, 87% in subarachnoid hemorrhage, 75% in contusion.Time from injury to surgical evacuation and type of surgical intervention did not affect mortality. Age and associated intracranial lesions were related to outcome. Severity of injury and pupillary response were the most important factors for predicting outcome.     

The bipartite tarsal navicular bone: Radiographic and computed tomography findings

Two cases of bipartite tarsal navicular bone are presented. The radiographic and computed tomography (CT) findings of this anatomical variant are described. Correct recognition of this entity is important, both because it may be the cause of symptoms perse, and because it may be misdiagnosed as a fracture. When plain films are not diagnostic, CT scanning is helpful in distinguishing between a fracture and this variant.     

Rupture of the posterior tibial tendon: CT and surgical findings

Computed tomography (CT) was performed in 42 patients with 49 clinically suspected tears of the posterior tibial tendon. Twenty-eight of the 49 suspected tears were subsequently surgically explored and repaired. Three patterns of tendon abnormalities were recognized on CT scans: type I-intact, hypertrophied, heterogeneous tendon; type II-attenuated tendon; and type III-absence of a portion of a tendon. Types I and II correlated with partial rupture seen during surgery, and type III correlated with complete rupture of the tendon. CT findings were accurate in 96% of the patients who underwent surgery. In four cases (14%), tendon rupture was seen on CT scans, but the extent of the injury was underestimated and the rupture was misclassified. Reactive periostitis of the distal tibia was seen in 71% of diseased tendons and may represent an important factor in the diagnosis of tendon rupture.

Isolated sphenoid sinus abscess: clinical and radiological failure in preoperative diagnosis. Case report and review of the literature

BACKGROUND: Isolated sphenoid sinusitis and abscess formation is a rare entity, which can lead to misdiagnosed or improperly treated patients and an unfavorable outcome. Invasion of the skull base and cavernous sinus usually causes cranial nerve palsies, suggesting a neoplasm at the initial presentation. CASE DESCRIPTION: A case of isolated abscess in the sphenoid sinus is reported. The complete destruction of the clivus and its unexceptional radiological data, in addition to the absence of clinical and laboratory evidence of infection, led us to misdiagnose a possible clival chordoma during preoperative evaluation. The patient underwent an endonasal-transsphenoidal procedure for diagnosis and surgical removal. Surgical drainage and prolonged antimicrobial treatment resulted in complete clinical recovery. CONCLUSION: Its close proximity to vital structures and slender bony structures may allow the infection to disseminate, with serious neurological complications. On the other hand, the variable clinical presentations and radiological data usually cause delayed or missed diagnosis in these cases. This emphasizes the importance of documentation of this unusual entity and its radiological manifestations.
